Skipping too many details - such as the crash flight having missing landing gear spacers, meaning it drifted off centerline and hit the debris that had fallen off a US aircraft. If it ran down the centerline, it would never have hit the debris. The US regulators and the Noise - Concorde was nowhere near as loud as maade out - the 'tests' that 'proved' the noise of sonic booms were done with a fighter jet at low level over a major city, and not at the Concorde's 60,000ft flight level, or over the farmland it was to fly over. Those 'tests', were biased through Boeing's interference and 'funding', because Boeing had already failed at making a US SSC.
Right now all resources should be focused on how to provide green air travel rather then pursue a supersonic plane thats highly unlikely to be commercialised and if it is will only be used by the very wealthy
I worked on the Concorde as a Braniff flight attendant because Braniff had a promotional interchange with Air France and British Airways in the late 70s. Braniff only flew it sub-sonic and we only flew it between Dallas and Washington DC. The week that I worked on it the flights were always brim-full. I sat in the aft jump seat (facing aft) and take-offs were especially thrilling. It felt and sounded like a rocket ship with my body thrown against the seat harness! Because we remained sub-sonic over the US, even at our cruising altitude the plane never leveled off. Pushing those carts uphill from the aft galley was a bit of a chore. No, really, I was very lucky to experience the Concorde!
The effects of sonic booms on the public was first tested in Tulsa, Oklahoma. After blowing out windows and tearing roofs off houses. The AIr Force moved just North of Oklahoma City for further testing. Now the Mojave desert is the only legal place to break the sound barrier in the states.
I got the same here. The audio recorded inside the plane sounded like his microphone was inside a cushion. Not good at all, quite annoying to try to understand. Even his studio audio is extremely bass-heavy. Very unusual for this channel - it’s normally fine.

I recall the TU144 was incredibly loud inside, so much so that you could barely have a conversation. And the air show crash was actually a result of a French surveillance airplane flying above (it was he reason the TU144 take off was delayed as the French had to wait for the surveillance airplane to get in position). When they climbed, their radar sounded a collision warning causing them to level off abruptly, stressing the plane beyond its design. The French and Soviets settled the case quietly as it was an embarrassment for both.
As someone with a toddler and family 4,000 miles away cutting the travel time down from 4 hours to two is a big deal. Though as someone with a toddler I might not be able to afford it...
Everytime I think of the Concorde, I think of "The Parent Trap" with Lindsey Lohan. They used the Concorde to get to London faster than the regular airline and profess his love for their mom.
Sonic booms are not the problem, the problem is with GHG restrictions we will be using less dense energy sources ( compare the best battery in w/kg to regular gas ) and Since the kinetic energy increases with the square of the speed, an object doubling its speed requires four times as much energy.
That’s just for static drag. If you include the supersonic drag, power is more like velocity cubed. That’s why supersonic flight is a dead-end. The amount of extra power required to go supersonic is just stupid and makes it horribly inefficient.

As long as the flight is long enough to justify it, the fuel burn rate wouldn't necessarily be hugely different if the plane were higher up - most of the fuel burn on the Concorde was keeping that speed up against the friction of the atmosphere - fly higher, less friction. Only works for long flights, though....
I spent most of my high school years of 1967-60 in San Diego, when military jets at Miramar and North Island regularly broke the sound barrier over populated and non-populated areas. It was the height of the Cold War after all. Learning to drive with the occasional sonic boom rattling my nerves was a hazard on top of the no seatbelts cars we had then. But I want to tell you about the 1967 trip I took to the Expo 67 Worlds Fair in Montreal Canada. A model of the Concorde was of course prominently displayed at the French and British pavilions, but it was there that the Russians made known that they would be building one too. I saw their Model TU-144 and did not expect that it was a real project. After all I had seen their display of color TVs that were built around an export version of the RCA shadow mask picture tube that also had been the basis of the Hitachi color TV I saw in a bar in the Tokyo Ginza in 1963 when there with the U.S. Navy ship I served aboard. The U.S. pavillion had a model SST too, as I recall, that could have solved the profitability issue, should it have been built. Swing wing, for much better landing and take-off performance, and 300 passenger capable, at least on paper. It represented our American pride of aerospace primacy. But for our government to build and test such a beast back then was going to impact that other program we had been spending roughly 4% of our GDP upon, the Apollo manned missions to the Moon. We did not want to fail at that one. So maybe that prohibition against supersonic overflights had been a product of of a governmental ruling with ulterior motives. It was well known that the airlines flying the Concorde hoped to add several inland cities on both sides of the Atlantic to their flight plans for it, which would have meant around a hundred of them being built. Had those factors have been possible, we might still be seeing them in the skies today.

Single engine transatlantic flight may be another hurdle. Regulations for Transoceanic flights for twin engine jet passenger aircraft had to be carefully drafted after reliability of twin engine jets proven. Single engine is a whole nuther issue for passenger service. “ETOPS, originally short for Extended-Range Twin Operations Performance Standards, or more recently just plain Extended operations, is the rating that allows twin-engined aircraft to fly long distances; particularly over large bodies of water like oceans.”
I'm more interested in electric planes. Quick swappable Aluminium Air batteries could make long distance EV planes viable. The battery is very light making it perfect for planes, just split it in many small modules so that swapping them out is easy. Charging a plane takes too much time anyway so battery swapping is the way to go.
Batteries are secondary stored energy and therefore always for inefficient than direct energy production. But, if government grants are your objective, battery powered planes can be profitable. If you're on Mars, battery powered might be more efficient than carrying your own solar panels.
@@friendlyone2706 Depends on where you get the energy from. Sure, putting a generator and a battery between an engine and the wheels doesnt make sense most of the time. But if you want to use other forms of energy (be it renewables (sun, wind, water, waves, biomass), or other types of fuels that cant be used for mobile applications (coal, trash, nuclear power)), a battery is often more efficient than power to fuel applications. Even here on earth.
One word: Starship. All of these developments are truly exciting, but by the time it arrives commercially, Starship will be whizzing 800 people at a time around in a fraction of the flight time, and since it's designed to be massed produced at a crazy scale, it'll probably even be cheaper! And you get to float in outer space for a few minutes as the cherry on top!
Watching this video I couldn’t help but think of two options. The expensive supersonic aircraft would be for low volume passengers. The ultra efficient aircraft would be for everyone else. In the future I could see the blended wing body with very high bypass ratio geared turbofans being possible. Both could possibly utilize rotating detonation turbines for the power section. The blended wing body might have a contra-rotating bypass fan like the NK-93 for maximum efficiency. The NK-93 was never funded enough to reach market but highlighted a possible path forward solving the noise issue of the CFM RISE and other propfans.
To increase fuel efficiency pilots throttle back slightly in a tailwind and throttle up slightly in a headwind affecting true airspeed, (TAS) accordingly.
I can see Hermes becoming a VIP Superjet. Maybe for the Sultan of Brunei or King Abdula of Abu Dhabi. Such a jet is as much statement of wealth as it is a strategic military transport.😊
My dad went on the first commercial flight of Concorde ie hired rather than a scheduled flight, think they flew over the Bay of Biscay and then back to Heathrow. Seriously jealous to this day as it was massively expensive by the time I could afford to travel and now not an oiption.
SpaceX released a UA-cam video in 2017, "Starship | Earth to Earth," suggesting much faster possible transport: less than an hour between any 2 places on the planet - half an hour for most trips. might be worth a look.
Apart of the technical issues (ie noise emissions, safety) My understanding on what partly of not almost entirely killed the supersonic travelling was just fuel cost and operation cost. Now there's additional carbon tax. I am not sure how commercially viable is this idea.
Exactly but one of the reasons it economically failed was because the US and several other countries restricted the route that a super sonic plane can travel due to sound complaints from residence (during the testing) with this new nasa method we could open lot more routes on top of that i think they might initially start as luxury type of plane marketed for rich people who by saving few hours of travel time could earn several times the ticket price......well just my guess but these planes atleast at the beginning might be exempted from carbon tax and hopefully one day bio fules become cheap alternative for petrol as electric planes are almost impossible within this century
@@bearcubdaycare yea but honestly I think that's just bs atleast for now the only way they could do that at present is using bio fules but the cost will shot up the roof adding it on top of the high fuel expense of supersonic jets.....it's suicide for any real company so i think it's either just marketing gimmick just like how Elon promising self driving cars for 10 years 😅
@@bearcubdaycare Meaning only those with private jets will experience reliable, fast travel to anywhere they choose. The rest of us will stay home, taking their word for what is happening elsewhere -- happy little ostriches with restricted flight options.
Keep in mind, we have CFD and better material science now compared to the 60s. We also have more mature engines like ramjets, scramjets and rotating detonation engines.
The ban on supersonic travel in the USA is an example of bad law making. The supersonic travel isn't a problem, the sonic boom was. So instead they should have banned travel that created more than x amount of noise.
as someone that does the london to LA trip more often than I thought I would, I wouldn't mind doing london to LA in under 6 hours, that's fro sure, I'm also down to have planes with fewer seats crammed in
A good exercise to figure out the issues so I wish them luck. The real problem will be economic feasibility for the operating airlines given the much reduce occupancy. Concorde had very limited routes and a great many airports that could not accommodate it, besides the very expensive ticket cost. Now we have virtual meetings and many fewer people that must travel.
my hopes and dreams are with Hermeus. Real Engineering did a vid on their engine and why its "only mach5, but around the world in few hours, flying on the edge of space sounds hella fun :)
14:03 Scaling up - Yep, once it's flyable and flying, Lockheed probly start looking at scaling up. Hmm... here's radical idea! Put passenger seating below and forward of pilot (in 747 deck configuration) ! Be a Monster, though!
Great job Ricky, but I feel if you’re going to adjust for today’s dollars. Fuel cost should be adjusted as well. zero chance a Concord and a 777 both cost the same per passenger mile. The slide before gave the 777 4.7x passenger mile advantage!
Could we get a video about the actual engineering? I really want to know exactly how that long nose and other parts of the engineering make a quieter supersonic boom. Good video, just didn't think I would get a video about history.
The fuel cost may not be what you think it will be. Consider the idea of the current adaptive cycle engines coming online for military jets, they make supersonic flight possible without using afterburners or even better fuelless engine designs using heat exchangers instead of dumping masses of fuel into the airstream.
@@simontillson482 I am not saying supersonic flight would be less energy-intensive than subsonic flight, just his baseline comparison looking at Concorde consumption levels vs the technological advancements we have today is off and will not be as prohibitive as he imagines.
@@thehobbyguy7089 Very true. The gap with modern technology is narrower, but it’s still wide enough to make it impractical. As mentioned in the video, even military jets only use supersonic flight to avoid interception and avoid it for cruise wherever possible, because it reduces their range so drastically. Honestly, I can’t see any reason for commercial supersonic flight. It just makes no sense. For long haul flights, the actual flight time is not a big proportion of the door-to-door time anyway, so even for business class, the cost/benefit ratio is very poor. It’s pretty much a gimmick at this point and will probably remain that way due to increasingly tighter controls on emissions and efficiency.
@@simontillson482 You remind me of the college professor who said we didn't need a new delivery service whose motto was "When it absolutely, positively, has to get there overnight." The professor was wrong. The student became rich. Sometimes people absolutely, positively have to get there faster.
@@friendlyone2706 Good point. Maybe it does make sense for the ultra-rich or executives with unlimited expense accounts. I did deliberately use the business class in my discussion for this reason. I ignored the idiot class deliberately… 🤓
Wondering if speakers, mounted on the exterior of the plane can provide a sound cancelling effect. Perhaps, it might be no good for propagating shock waves.
Surprised that the Concorde got canceled, after the crash and high prices for running it, why they didn't try to update it with new engines and new tech?
The real problem of today's air travel is that check in takes over 1h and requires you to strip to your underwear. And often the airport is hours away. So 1h flight time comes with 4h pre and post flight time.
You are correct. It is half that distance, so 7000 miles round trip. Ultimately the limited range was the main reason no American airline purchased it. It could not go from London to Texas directly and it was a business failure.
audio is muffled. and for the "get better speakers! change your settings!" rebuttals. i can just open up any other video produced by twobitdavinci and they are markedly better, as are every other normal video i watch right now, same setup edit: clears up a bit with more higher frequency at about 8:10
All the projects for supersonic planes you mention are for business jets. Not sure you'll get to do your supersonic flight if these go into service, even at $14000. Plus, what would be the point anyway in supersonic airliners for the masses? NY to LA: 1 hour travel to airport, check in 2h before flight, fly 2.5h, 1 hour travel from airport to city = 6.5h. On a far cheaper subsonic flight, that would be 9h. Is that really worth the expense if you're not super rich?
Business flight: Helicopter from downtown Manhattan to JFK, 5 minutes ($200). no TSA, arrive moments before flight, 2.5 hour flight time, helicopter to destination from airport, another 5 minutes depending on destination. Less than 3 hours not 6.5
The Concord was the perfect epitome of class domination. If you can afford a $14,000 ticket you can burn carbon with a fraction of the efficiency of a normal airplane and as an added bonus you get to let all of the peasants beneath you know with an annoyingly loud boom. The next generation of supersonic jets do largely the same thing, except this time they create venture capital fueled financial bubbles as well. This entire project is a sick joke, especially in a country whose railways are slower now than they were a century ago.
One thing to remember @TwoBitDaVinci is that a lot of this research is funded by oil companies, especially those in Dubai, to justify and continue fossil fuel extraction. The question is, do we need super sonic flight when we could be investing this wealth and human power into more sustainable tech. Remember, sustainable tech isint sexy or exciting, but it means we get to live another day, and I much rather have that then a drug filled crazy party one night, and a burning world the next.
While it would be foolish to say "never", I can't see it being anything but a tiny niche for the foreseeable future. When all you could do on a plane was read or watch movies or sleep, people would be willing to pay a fair amount more for a quicker flight. Now that you can do most anything on a computer during a flight, paying much more for a quicker flight just isn't worth it. Sure, maybe some people will do it occasionally. But again, almost certainly nothing but a tiny niche for the foreseeable future.
Wow, I still need a $14,000 ticket to fly at the speed of sound. No way Mr Two Bit Da Vinci! Perhaps the military is interested in this technology & perhaps even funding it. Look at rotary combustion jet engines to learn about a less expensive way to travel at the speed of sound.
I think SpaceX will achieve point to point commercial services before quiet supersonic planes imo. NY to LA in 2 hours? How cute. Starship will do US to the other side of the world in 90 mins.
0:39 in and already wrong. Supersonice flight has been continuing since the concord was retired. F-18, F-15, F-16, B-2, F-22, F-35, and the coolest of all the SR-71. All supersonic. And I think there are even SR-71 has a couple still in service and I think the A10 tank killer is super sonic but I'm not sure. Supersonic passenger flight is a different story. The Concord was a very odd bird and had several problems to start with. Since before it retired there have been attempts to make a better supersonic jetliner but there were several challenges to overcome. I know, I worked on the High Speed Civil Transport project before it died in the '90s. It will be interesting to see how those challenges are met and interesting if you know any of them.
The engineering aspect is interesting, but why are we still putting so much into more CO2 emissions? We need to work on making an electric propulsion that can go fast and far, not more of the same costly burning we've been doing for years.
These projects are cool and all but I am most interested in hydrogen and electric aircraft. Both the adapted reuse of existing airlines refitted for hydrogen like Universal Hydrogen is proposing but also new designs that incorporate it from the get go... Most of the new blended body aircraft including the Bombardier Ecojet design are counting on this being the future of aviation... And I kind of hope it is!
It seems feasible but if if used nuclear fuel, which would not be much. Sure it does come with some risk but there is less chance for an explosion and would be much safer.
I think it will be cheaper to build trains ..China already is coming out with trains that will run 1000km/h ...And the semi vacuum tube system with 4000km/h is planned... 3.2 times the speed of sound... Unless you can build planes faster and cheaper ....Furthermore train stations are more convenient than airports
They can only minimize it. Boeing's Sonic Cruiser concept in the 90's of going to high subsonic speed. But they still couldn't solve the fuel burn issue.
how is the sonic boom an issue over land if a plane has control of its speed. heres an idea, dont go fast over land until you are over sea. then hit the gas and boomboomboom lets go back to my room.
From an engineering standpoint of course all of this is fun and impressive. We live in a new reality though where we have to decarbonise to the point of zero emissions so inefficient fuel hungry aircraft like that don't have a place anymore. I can't see these pipe dreams becoming a reality.
It is certainly a nightmare situation and yes unfortunately the crisis is self inflicted but there is nothing to wake up from unless of course you think it's all fake or overblown, then unfortunately you would have to wake up.
@@ronankierans1600 I woke up long ago and have been watching the characters trying to change the world to their wishes. CO2 is an important gas that's necessary for life on the planet. We're at a near all time low and if it gets much lower, we'll be in trouble. While temperatures here ARE increasing, the activists are approaching things from the wrong direction. But they're getting quite wealthy while doing so.
Bro, I forgot you were an aerospace engineer. Have you seen the latest developments in Carbon Fiber Batteries? Also, my latest video proposes an alternative way to take off, for electric flight. Would love your thoughts on that - would mean a lot to me, as I am a huge fan. And on that, yet another great video and thank you for keeping us all informed with the positive developments out there and inspiring us all. 🙏
NASA MAY have! MAY HAVE found ONE solution to ONE specific problem. And there are LOADS more problems to be solved before sustainable supersonic passenger service is available. Sonic booms over land is the one they MAY have found an answer too for a given CONFIGURATION. Is that configuration usable by commercial airlines? We will have to wait and see. The bigger issues fall into the realms of systems management (Efficient aerodynamic load control), logistics Engine maintenance and parts) and economics (Fuel costs and useful load)! These are the money shots! Anyone saying different is selling swamp bottom land. The Concord never made a dime in its life. It was a money pit.
A windowless cockpit sounds very cool and sci-fi, but I can easily see that idea being ditched the moment someone remembers that it is actually possible for electronic systems to fail. Either that or after the first of those planes crashes, killing everyone aboard, because the electronics failed.

I'm more interested in electric planes. Quick swappable Aluminium Air batteries could make long distance EV planes viable. The battery is very light making it perfect for planes, just split it in many small modules so that swapping them out is easy. Charging a plane takes too much time anyway so battery swapping is the way to go.
Batteries are secondary stored energy and therefore always for inefficient than direct energy production. But, if government grants are your objective, battery powered planes can be profitable. If you're on Mars, battery powered might be more efficient than carrying your own solar panels.
@@friendlyone2706 Depends on where you get the energy from. Sure, putting a generator and a battery between an engine and the wheels doesnt make sense most of the time. But if you want to use other forms of energy (be it renewables (sun, wind, water, waves, biomass), or other types of fuels that cant be used for mobile applications (coal, trash, nuclear power)), a battery is often more efficient than power to fuel applications. Even here on earth.
@@justinterested5819 Batteries do have their uses. And going downhill can be recharged -- even on the moon and Mars.
One word: Starship.
All of these developments are truly exciting, but by the time it arrives commercially, Starship will be whizzing 800 people at a time around in a fraction of the flight time, and since it's designed to be massed produced at a crazy scale, it'll probably even be cheaper!
And you get to float in outer space for a few minutes as the cherry on top!
Watching this video I couldn’t help but think of two options. The expensive supersonic aircraft would be for low volume passengers. The ultra efficient aircraft would be for everyone else. In the future I could see the blended wing body with very high bypass ratio geared turbofans being possible. Both could possibly utilize rotating detonation turbines for the power section. The blended wing body might have a contra-rotating bypass fan like the NK-93 for maximum efficiency. The NK-93 was never funded enough to reach market but highlighted a possible path forward solving the noise issue of the CFM RISE and other propfans.
Keep up the great work on educating the public
Been waiting my entire aerospace career to build one. Alot of talk and demonstration happened since the 1990's
To increase fuel efficiency pilots throttle back slightly in a tailwind and throttle up slightly in a headwind affecting true airspeed, (TAS) accordingly.
I can't wait for the time when Hermeus and Starship Earth To Earth become competitors
I can see Hermes becoming a VIP Superjet. Maybe for the Sultan of Brunei or King Abdula of Abu Dhabi. Such a jet is as much statement of wealth as it is a strategic military transport.😊
My dad went on the first commercial flight of Concorde ie hired rather than a scheduled flight, think they flew over the Bay of Biscay and then back to Heathrow. Seriously jealous to this day as it was massively expensive by the time I could afford to travel and now not an oiption.
SpaceX released a UA-cam video in 2017, "Starship | Earth to Earth," suggesting much faster possible transport: less than an hour between any 2 places on the planet - half an hour for most trips. might be worth a look.
Apart of the technical issues (ie noise emissions, safety)
My understanding on what partly of not almost entirely killed the supersonic travelling was just fuel cost and operation cost.
Now there's additional carbon tax.
I am not sure how commercially viable is this idea.
Exactly but one of the reasons it economically failed was because the US and several other countries restricted the route that a super sonic plane can travel due to sound complaints from residence (during the testing) with this new nasa method we could open lot more routes on top of that i think they might initially start as luxury type of plane marketed for rich people who by saving few hours of travel time could earn several times the ticket price......well just my guess but these planes atleast at the beginning might be exempted from carbon tax and hopefully one day bio fules become cheap alternative for petrol as electric planes are almost impossible within this century
@@Life_is_miraculusBoom has said they're targeting 100% SAF (sustainable aviation fuel).
@@bearcubdaycare yea but honestly I think that's just bs atleast for now the only way they could do that at present is using bio fules but the cost will shot up the roof adding it on top of the high fuel expense of supersonic jets.....it's suicide for any real company so i think it's either just marketing gimmick just like how Elon promising self driving cars for 10 years 😅
@@bearcubdaycare Meaning only those with private jets will experience reliable, fast travel to anywhere they choose. The rest of us will stay home, taking their word for what is happening elsewhere -- happy little ostriches with restricted flight options.
Keep in mind, we have CFD and better material science now compared to the 60s. We also have more mature engines like ramjets, scramjets and rotating detonation engines.
As a teenager in the '70s, I was in the ground relatively close to an aircraft breaking the sound barrier....a sonic boom is impressive....
The ban on supersonic travel in the USA is an example of bad law making.
The supersonic travel isn't a problem, the sonic boom was.
So instead they should have banned travel that created more than x amount of noise.
Since when do legislators have common sense?
@@OneWildTurkey since before they could be legally bought I guess. ;)
@@Robbedem 💯😃
Please pull this video and fix the audio and re-release I can't watch this. It looks like a great video.
Great video. Would love to see you break down the aerodynamic design used in formula one. How it works and what could it be like in the future.
Concorde, oh yeah
as someone that does the london to LA trip more often than I thought I would, I wouldn't mind doing london to LA in under 6 hours, that's fro sure, I'm also down to have planes with fewer seats crammed in
A good exercise to figure out the issues so I wish them luck. The real problem will be economic feasibility for the operating airlines given the much reduce occupancy. Concorde had very limited routes and a great many airports that could not accommodate it, besides the very expensive ticket cost. Now we have virtual meetings and many fewer people that must travel.
Hat tip to the jazzed-up intro!
my hopes and dreams are with Hermeus. Real Engineering did a vid on their engine and why its "only mach5, but around the world in few hours, flying on the edge of space sounds hella fun :)
14:03 Scaling up - Yep, once it's flyable and flying, Lockheed probly start looking at scaling up. Hmm... here's radical idea! Put passenger seating below and forward of pilot (in 747 deck configuration) ! Be a Monster, though!
Great job Ricky, but I feel if you’re going to adjust for today’s dollars. Fuel cost should be adjusted as well. zero chance a Concord and a 777 both cost the same per passenger mile. The slide before gave the 777 4.7x passenger mile advantage!
Could we get a video about the actual engineering? I really want to know exactly how that long nose and other parts of the engineering make a quieter supersonic boom. Good video, just didn't think I would get a video about history.
90 minutes across the pond...sounds awesome...until they tell you to arrive 3 hours early for international flights.
Ty for takin time to teach lil ones proper oral care
The fuel cost may not be what you think it will be. Consider the idea of the current adaptive cycle engines coming online for military jets, they make supersonic flight possible without using afterburners or even better fuelless engine designs using heat exchangers instead of dumping masses of fuel into the airstream.
No matter what engines you use, supersonic flight is always going to be way less efficient than subsonic. This argument doesn’t work I’m afraid.
@@simontillson482 I am not saying supersonic flight would be less energy-intensive than subsonic flight, just his baseline comparison looking at Concorde consumption levels vs the technological advancements we have today is off and will not be as prohibitive as he imagines.
@@thehobbyguy7089 Very true. The gap with modern technology is narrower, but it’s still wide enough to make it impractical. As mentioned in the video, even military jets only use supersonic flight to avoid interception and avoid it for cruise wherever possible, because it reduces their range so drastically. Honestly, I can’t see any reason for commercial supersonic flight. It just makes no sense. For long haul flights, the actual flight time is not a big proportion of the door-to-door time anyway, so even for business class, the cost/benefit ratio is very poor. It’s pretty much a gimmick at this point and will probably remain that way due to increasingly tighter controls on emissions and efficiency.
@@simontillson482 You remind me of the college professor who said we didn't need a new delivery service whose motto was "When it absolutely, positively, has to get there overnight." The professor was wrong. The student became rich. Sometimes people absolutely, positively have to get there faster.
@@friendlyone2706 Good point. Maybe it does make sense for the ultra-rich or executives with unlimited expense accounts. I did deliberately use the business class in my discussion for this reason. I ignored the idiot class deliberately… 🤓
Wondering if speakers, mounted on the exterior of the plane can provide a sound cancelling effect. Perhaps, it might be no good for propagating shock waves.
Surprised that the Concorde got canceled, after the crash and high prices for running it, why they didn't try to update it with new engines and new tech?
The real problem of today's air travel is that check in takes over 1h and requires you to strip to your underwear. And often the airport is hours away. So 1h flight time comes with 4h pre and post flight time.
Business flights (not business class) don't require TSA and helicopters aren't much more than the travel time cost plus the vehicle.
I would never fly on the Concord. 1) too expensive, 2) too cramped
Absolutely love your channel... I don't think it's a 7000 miles from New York to Linda...
You are correct. It is half that distance, so 7000 miles round trip. Ultimately the limited range was the main reason no American airline purchased it. It could not go from London to Texas directly and it was a business failure.
Seems to me combining two shock waves out of phase 180 degrees is the only real solution. How this can be done is the challenge.
fly higher and no noticeable sonic boom on the ground.
a toothbrush with a fucking app. Hell nah.
audio is muffled. and for the "get better speakers! change your settings!" rebuttals. i can just open up any other video produced by twobitdavinci and they are markedly better, as are every other normal video i watch right now, same setup
edit: clears up a bit with more higher frequency at about 8:10
11:18 Proposed aircraft: With capacities under 15 or 20 people, they are merely executive jets that the general public will only see in magazines, &c.
All the projects for supersonic planes you mention are for business jets. Not sure you'll get to do your supersonic flight if these go into service, even at $14000. Plus, what would be the point anyway in supersonic airliners for the masses? NY to LA: 1 hour travel to airport, check in 2h before flight, fly 2.5h, 1 hour travel from airport to city = 6.5h. On a far cheaper subsonic flight, that would be 9h. Is that really worth the expense if you're not super rich?
Business flight: Helicopter from downtown Manhattan to JFK, 5 minutes ($200). no TSA, arrive moments before flight, 2.5 hour flight time, helicopter to destination from airport, another 5 minutes depending on destination.
Less than 3 hours not 6.5
Field momentum vehicles will out class any plane in the future.
Seems like the perfect solution for Taylor Swift. Cost is no object, room for one person. Perfect. She just needs to get certified to fly it.
The Concord was the perfect epitome of class domination. If you can afford a $14,000 ticket you can burn carbon with a fraction of the efficiency of a normal airplane and as an added bonus you get to let all of the peasants beneath you know with an annoyingly loud boom. The next generation of supersonic jets do largely the same thing, except this time they create venture capital fueled financial bubbles as well. This entire project is a sick joke, especially in a country whose railways are slower now than they were a century ago.
One thing to remember @TwoBitDaVinci is that a lot of this research is funded by oil companies, especially those in Dubai, to justify and continue fossil fuel extraction. The question is, do we need super sonic flight when we could be investing this wealth and human power into more sustainable tech. Remember, sustainable tech isint sexy or exciting, but it means we get to live another day, and I much rather have that then a drug filled crazy party one night, and a burning world the next.
8:00 apparently true for this video as well. 😅 love your stuff though but thought it was ironic.
While it would be foolish to say "never", I can't see it being anything but a tiny niche for the foreseeable future. When all you could do on a plane was read or watch movies or sleep, people would be willing to pay a fair amount more for a quicker flight. Now that you can do most anything on a computer during a flight, paying much more for a quicker flight just isn't worth it. Sure, maybe some people will do it occasionally. But again, almost certainly nothing but a tiny niche for the foreseeable future.
How long from NY to Sydney? NY to Delhi?
Audio sounds a bit like you recorded it under a blanket.
Environmental concerns will surely prevent these from coming to commercial production. To much CO2 added for to few people being moved.
Boom has said they're targeting 100% SAF (sustainable aviation fuel) for their aircraft.
Wow, I still need a $14,000 ticket to fly at the speed of sound. No way Mr Two Bit Da Vinci! Perhaps the military is interested in this technology & perhaps even funding it. Look at rotary combustion jet engines to learn about a less expensive way to travel at the speed of sound.
I think SpaceX will achieve point to point commercial services before quiet supersonic planes imo. NY to LA in 2 hours? How cute. Starship will do US to the other side of the world in 90 mins.
0:39 in and already wrong. Supersonice flight has been continuing since the concord was retired. F-18, F-15, F-16, B-2, F-22, F-35, and the coolest of all the SR-71. All supersonic. And I think there are even SR-71 has a couple still in service and I think the A10 tank killer is super sonic but I'm not sure. Supersonic passenger flight is a different story. The Concord was a very odd bird and had several problems to start with. Since before it retired there have been attempts to make a better supersonic jetliner but there were several challenges to overcome. I know, I worked on the High Speed Civil Transport project before it died in the '90s. It will be interesting to see how those challenges are met and interesting if you know any of them.
The engineering aspect is interesting, but why are we still putting so much into more CO2 emissions? We need to work on making an electric propulsion that can go fast and far, not more of the same costly burning we've been doing for years.
Russia just couldn't market their wins well enough outside of their close loop
Wow, why is the audio so duff?
MAKE NOISE TOLERABLE? SO AS LONG AS IT DOESN’T BREAK YOU WINDOWS
These projects are cool and all but I am most interested in hydrogen and electric aircraft. Both the adapted reuse of existing airlines refitted for hydrogen like Universal Hydrogen is proposing but also new designs that incorporate it from the get go... Most of the new blended body aircraft including the Bombardier Ecojet design are counting on this being the future of aviation... And I kind of hope it is!
It seems feasible but if if used nuclear fuel, which would not be much. Sure it does come with some risk but there is less chance for an explosion and would be much safer.
14k per seat in 1989? How was it not profitable?
Supersonic commercial flight is still 50+ years away.
You need to check your sound system before releasing the videos.
sonic boom was never that bad. i would bet if concorde had been a Boeing plane that regulation would never have happened.
SpaceX? 🤔 Speed and number of people in one flight? 🤔
I think it will be cheaper to build trains ..China already is coming out with trains that will run 1000km/h ...And the semi vacuum tube system with 4000km/h is planned... 3.2 times the speed of sound... Unless you can build planes faster and cheaper ....Furthermore train stations are more convenient than airports
And after the first tectonic plate shift, they can rebuild the tunnel.
I mean you can bring up the cybertruck but that seems like a TERRIBLE example.
9:32 About halfway through... So NASA has NOT YET solved the booming?
They can only minimize it. Boeing's Sonic Cruiser concept in the 90's of going to high subsonic speed. But they still couldn't solve the fuel burn issue.
They use 3X as much fuel per passenger. Check out "Climate Town, Saudi Arabia's plan to keep us hooked on oil" .
Ya, I didn't watch your entire vid Ricky. What are you selling now after getting STBD wrong!
how is the sonic boom an issue over land if a plane has control of its speed. heres an idea, dont go fast over land until you are over sea. then hit the gas and boomboomboom lets go back to my room.
From an engineering standpoint of course all of this is fun and impressive. We live in a new reality though where we have to decarbonise to the point of zero emissions so inefficient fuel hungry aircraft like that don't have a place anymore. I can't see these pipe dreams becoming a reality.
Eventually people will awaken from their self imposed nightmare and realize we're at a CO2 shortage.
It is certainly a nightmare situation and yes unfortunately the crisis is self inflicted but there is nothing to wake up from unless of course you think it's all fake or overblown, then unfortunately you would have to wake up.
@@ronankierans1600 I woke up long ago and have been watching the characters trying to change the world to their wishes. CO2 is an important gas that's necessary for life on the planet. We're at a near all time low and if it gets much lower, we'll be in trouble. While temperatures here ARE increasing, the activists are approaching things from the wrong direction. But they're getting quite wealthy while doing so.
Bro, I forgot you were an aerospace engineer. Have you seen the latest developments in Carbon Fiber Batteries?
Also, my latest video proposes an alternative way to take off, for electric flight. Would love your thoughts on that - would mean a lot to me, as I am a huge fan.
And on that, yet another great video and thank you for keeping us all informed with the positive developments out there and inspiring us all. 🙏
What the fuck did you use as the background music for the X-59? How horrifying is that?!
Can barely hear the audio
Good video but poor audio quality. You need to work on your microphone technique.
NASA MAY have! MAY HAVE found ONE solution to ONE specific problem. And there are LOADS more problems to be solved before sustainable supersonic passenger service is available.
Sonic booms over land is the one they MAY have found an answer too for a given CONFIGURATION. Is that configuration usable by commercial airlines? We will have to wait and see.
The bigger issues fall into the realms of systems management (Efficient aerodynamic load control), logistics Engine maintenance and parts) and economics (Fuel costs and useful load)! These are the money shots! Anyone saying different is selling swamp bottom land.
The Concord never made a dime in its life. It was a money pit.
Beleive it when i see it.
A windowless cockpit sounds very cool and sci-fi, but I can easily see that idea being ditched the moment someone remembers that it is actually possible for electronic systems to fail.
Either that or after the first of those planes crashes, killing everyone aboard, because the electronics failed.
Really mushy audio.
Supersonic travel died the minute they banned over land flight.
Only the rich will enjoy supersonic flight.
Konkordski in Russia was not breaking windows and disturbing da people?
this is such a random sponsor… I mean, just replace the word "toothbrush" by shmex toy and the advert even sounds more suiting 😂
