I've watched half dozen of your videos and I've officially subscribed and thumbs up. Your editing and commentary are solid and worth investing in. Many thanks for your hard work, effort and delivery!
Imagine if Dorothy Vaughan or Dr. Emeagwali was on it. No offense, but when just one type of people, work on something, they usually end up with something like the Atomic Bomb or Nuclear Power Plants. Nothing good for the Earth.
Great video and super interesting, but I really wish they touched on the headwinds (pun most definitely intended) they’ll face trying to limit how loud the sonic booms would be from hypersonic jets. Would love to be proven wrong (or dumb), but I can’t imagine people would be happy with 200 dB booms raining down on them every time one of these jets flies over them.
I'd love to see you do a video on reaction engines. Alan Bond has been chipping away at zero to hypersonic since the 70s but is really starting to get there.
Did they build the hypersonic engine or are they still trying? Love the fact that a lot of this endeavor is talking about the way you need to take to get somewhere instead of how they are going to make this hypersonic work. This shows the world we are living in. Thanks for the share, good work ✌️
So they have made a ground tested version of there engine that has been tested at hypersonic airflow speeds. The next step is making a airborne engine using lightweight materials
Adiabatic heating. That's what will kill this project. A big breakthrough is needed to build a hypersonic vehicle that flies more than once. My bet is transpiration cooling. Otherwise what are they going to do? Spray it with a fresh coat of ablative cooling paint before every flight? Even transpiration cooling will add significant weight and complexity. If they were using cryogenic fuel, they could circulate that through the leading edges I suppose.
Funny how most of your videos start with something i absolutely don’t know anything about, and end up being much more interesting than the subjects I usually watch. The storyteller is at least as important as the story itself !
Nicely done John and team. As I have pitched you in the past, Destinus is a European startup based in Switzerland in the business of ultra high-speed, green air transportation using hydrogen and ramjet engine tech with proprietary afterburners. You might be interested to compare the different paths between the US and EU with respect to hydrogen infrastructure and regulatory approvals. Destinus has a very aggressive time scale for proof of concept.
The Concorde flew passengers at mach 2 on January 21, 1976 for the first time. It has been 48 years since then. I don't get why they wouldn't work flying passengers.
You don't really see flight trajectory mentioned anywhere, likely because it's probably, questionably, the achilles heel of the entire project. With that air breathing engine, and that speed, they're not going to be able to get high enough to get above the Tom Cruise Darkstar problem. Not without taking significant amounts of heat damage. That's a massive logistics problem for commercial airline services turnaround times.
excellent! to bad the video didn't mention the "Leduc 022" or the "Nord 1500 Griffon". two french planes that flew with hybride ramjet propulsion in the 50's ;)
Is this an Aerospike engine? Is the vehicle a SSTO, is that its ultimate goal? What is the motor's Specific Impulse (I^sp)? I don't recall them saying.
22:15 in before we hear them say the actual goal of the company. They're trying to be a defence contractor, but promote some lofty goals to revolutionize civilian air travel to guarantee they get their slice of the US military budget. We'll see hypersonic cruise missiles long before you ever get to fly from LA to TYO in three hours.
Hypersonic Air Force One… On one of the Episodes of the “Six Million Dollar Man” TV series, Oscar Goldman travelled in an F104 Starfighter. There could be a hypersonic vehicle to get a President, Cabinet member or General quickly somewhere. Good idea
I understand when tech people say "Let's break things and move fast", but when engineers say "We basically jump off the cliff and build a plane while falling" it is not encouraging at all.
I love how all these "Startups" trying to get a piece of the arms sales pie, keep telling us how their technology could change the world, end conflicts and help the world for the better, while all it does is help armies bomb some villages in Iraq or Afghanistan.
A good friend of mine works there as a propulsion engineer and I’ve met the CEO. In just about every startup there’s going to be some hype, but from what I can tell they have solid resources, talents, and contracts to make it happen.
At 11:54, this video states that transitioning from a turbo jet engine at low speed to a ram jet engine at high speed has never been done in flight. I thought the SR 71 did that routinely starting in the 1960s?
Selling the idea of need of pocket Concord for 20 ppl in the era of facetime meetings around the globe sounds bit obsolete to me. Especially in the post pandemics era. Yep we need such propulsion but I see most of it use in the military area.
Can you please make video on G20 In India and Indian government's stance on Muslims and current geopolitical challenges for the country Also: please cover bbc ban in india
The video forgot to mention that Russia has Two Hypersonic attack Missiles and is the only country with Air defense that can take out Hypersonic Missiles. Russia is in a race to build Hypersonic Planes and drones at the moment. I can't understand why hermius isn't getting funding from the start?
Kids in a candy store with "Other people's money." We barely have reliable hypersonic rockets, let alone a plane, LET ALONE a plane that will haul a few hundred people that won't haul them to their deaths. I see nothing but very pumped-up enthusiasm here, not any outstanding engineers or physicists. MACH FIVE for a plane carrying humans that would be over a hundred feet long?? ANOTHER thing is, the word, "Revolutionary." Let's think about that one: Who will be able to afford a flight on this plane? Only C.E.O.S and other extremely wealthy people. It will revolutionize the top 1/50th percent of the business class. I see bankruptcy and failure first, if not, TITAN type of headlines all over the media involving this.
Mr koshla is smart! There is a standing need for jet engine demand from India both military and civilian, and we are sick of legacy manufacturers! We need cheaper faster better.
This seems way more of a military use thing. Rather than a commercial travel use thing? Who knows? Maybe they will find a way to change the way things function? Will see..
I don't think mach 5 passenger travel is economically feasible. Military may be more Interested but satellites do a good job compared to planes so it would not justify its use.
Cool video, as always. But two things really strike my nerve.. 1) _”We’re gonna build a commercial plane. (few moments later:) We’re building a next generation warplane!_ 2) Who the hell, besides the rich, needs commercial hypersonic flight?? What problem does it solve? Sounds purely counterintuitive when it comes to climate change!
It's great to see this hypersonic technology, but I think efficiency and safety will be affected. It's better to build a commercial aircraft that travels at 1500km/hr, with more efficiency than today, that's almost double the speed of what today's aircrafts fly.
Wonder how efficient this will be and what environmental impact this would have if we used these to speed up the world 5x... or whether they've thought of how to actually make this work in an environmentally friendly manner. Otherwise it's probably just more the 0.1% burning more to do things faster for themselves.
I have not watched the whole video, but I was thinking the same thing. Flights are already crazy expensive, most of the time, for any halfway decent airline. On top of this, all we hear in the news cycle, is about how we have to stop using fossil fuels. I have a feeling that this tech will end up being used by the wealthy, like you said.
The good news with something like this is that because of the way that ramjet technology works, once it's up to speed (roughly, over mach 3), it's actually more efficient than a turbojet. Although you would make a lot more individual flights with a small craft like this as opposed to bringing an entire group of people at once, the aircraft would spend a much greater percentage of time in a higher efficiency mode. So overall, you're saving fuel and burning it cleaner as well as saving time. Honestly, if this works, it will revolutionize international travel beyond what this video even implies.
90 minutes? what the heck am i going to do sitting in a chair for 90 minutes? i want teleportation! 🙂 i want to get where i'm going instantly....so i can waste hours watching youtube when i get there. oh wait...i could watch youtube on the plane...
The SR-71 had a turboramjet back in the sixties, it took off as a turbojet and transisioned to ramjet. THE FUCK YOU TRYIN TO SAY IT HASN'T BEEN DONE BEFORE?
this video is gushing with finance bro hype and filler gargon and ZERO any technical insight as to what makes them any different/better from everything that came before and exists now.
I've watched half dozen of your videos and I've officially subscribed and thumbs up. Your editing and commentary are solid and worth investing in. Many thanks for your hard work, effort and delivery!

@@DuckyIsLiveI got 1.5k 👍🏽, for noticing what the narrator, missed. In 2-3 days.
this is the kind of content I want. Well done John,
This was beautiful
This is an awesome video showing not just the technology but the steps and challenges development hast to go through
Great video and super interesting, but I really wish they touched on the headwinds (pun most definitely intended) they’ll face trying to limit how loud the sonic booms would be from hypersonic jets. Would love to be proven wrong (or dumb), but I can’t imagine people would be happy with 200 dB booms raining down on them every time one of these jets flies over them.
There is actually a NASA Project running that does research around the problem of super sonic booms. Its called X-59. Pretty cool
Another home run episode John. Thank you for thorough journalism showcasing the pioneering work others are doing.
John always keeps coming back with extraordinary analysis we missed you John ❤❤
I'd love to see you do a video on reaction engines.
Alan Bond has been chipping away at zero to hypersonic since the 70s but is really starting to get there.
I respect this man's work 🙏🏾
Did they build the hypersonic engine or are they still trying?
Love the fact that a lot of this endeavor is talking about the way you need to take to get somewhere instead of how they are going to make this hypersonic work.
This shows the world we are living in.
Thanks for the share, good work ✌️
They seem to. From what I understood the real challenge is to make a commercial version that is cheap and reliable
So they have made a ground tested version of there engine that has been tested at hypersonic airflow speeds. The next step is making a airborne engine using lightweight materials
I remember hearing about this hypersonic plane 32 years ago, its about time!!
Keep waiting
Great video as always man, I don't understand how your channel isn't way bigger. Keep at it and I promise you'll get there

What did Concorde do about this issue?
@@jonathanvanwersch8500 they didn't, Concorde wasn't a hypersonic aircraft.
Funny how most of your videos start with something i absolutely don’t know anything about, and end up being much more interesting than the subjects I usually watch. The storyteller is at least as important as the story itself !
For the first time combination of inventors and inovators that really want to make practical change and profit not just the money.
Fantastic!!!
Best info and presentation on hypersonics ;
And LOVED you had Alex Hollings from Sandbox in this vid!!

No mention of the sonic boom problem?
What a great investment pitch... did you buy?
It's that kind of hypersonic plane taking flight for the first time, for all its expense, that will truly make the world that much smaller.
I've been looking forward to the Coogan X Hermeus video for awhile, let's go!
Not this again....Hypersonic engine sure, but commercial planes with these engines is not going to work if you want to fly at M5
The Concorde flew passengers at mach 2 on January 21, 1976 for the first time. It has been 48 years since then. I don't get why they wouldn't work flying passengers.

That's a massive logistics problem for commercial airline services turnaround times.
The thing is they need to make the plane cheaper so the tickets are low enough that everyone can fly supersonic
What about fuel usage for same distance compared to an ordinary passenger plane?
I just found your channel tonight, I've watched a lot of the videos on binge, really good content! Keep it up, man!
This was an unexpected video but very very cool.
John Coogan did not mention Boom Supersonic, a real contender to Hermeus!
Incredible information! Incredible innovation!
Awesome Video !!!! Keep these videos' coming
excellent! to bad the video didn't mention the "Leduc 022" or the "Nord 1500 Griffon". two french planes that flew with hybride ramjet propulsion in the 50's ;)
What about the scary sonic boom? Wasn't that the main problem of Concord??
Is this an Aerospike engine? Is the vehicle a SSTO, is that its ultimate goal? What is the motor's Specific Impulse (I^sp)? I don't recall them saying.
Bro just did spaceman "you got peanut butter in my chocolate"
What about all the fire? That’s what engines do. They make a fire. Priceless. 😅
Very inspiring to see fellow Yellow Jacket PhDs doing incredible work!
i feel it's a scam but let us see what will happen.....
thanks for the amazing video as usual .. perfect
it seems like more people are interested working for NASA and other big companies like this just to have it on their résumé.
Nice PR video

Hypersonic Air Force One…

Great video! Teaching engineering, business, and politics this way will be much more helpful and motivating.
Speed is money. I see blackbirds turbo ramjet engines in these designs mixed with XB-70 Valkyries compression lift theory in wing droop design.
"This technology is already existed for decades"
*proceeds to show supersonic technology instead of hypersonic technology*
I understand when tech people say "Let's break things and move fast", but when engineers say "We basically jump off the cliff and build a plane while falling" it is not encouraging at all.
the SR-71 or commonly known as the blackbird actually used a ramjet-turbojet combo

Waiting for a DEBUNKED / BUSTED video from thunderf00t in order to understand whether it is HYPERSONIC OR JUST HYPE
A good friend of mine works there as a propulsion engineer and I’ve met the CEO. In just about every startup there’s going to be some hype, but from what I can tell they have solid resources, talents, and contracts to make it happen.
I want thunderf00t as my CTO
@@3nityC Yep, he will save us alot of money
I smell failure.
Got it been thinking of this since 8-9 years old(1970-72) still have not seen it yet within combustible limits
This is an Ad for the company producing the plane. Bought and paid for presented by John Kooken.
Best content around 👌
SpaceX starship: hold my beer
At 11:54, this video states that transitioning from a turbo jet engine at low speed to a ram jet engine at high speed has never been done in flight. I thought the SR 71 did that routinely starting in the 1960s?
So how did you showcase the ramjet at the party with static plane?
Top Gun Maverick enabling engine tech right here 😎
where would you store the fuel though?
Selling the idea of need of pocket Concord for 20 ppl in the era of facetime meetings around the globe sounds bit obsolete to me. Especially in the post pandemics era. Yep we need such propulsion but I see most of it use in the military area.
Is that the Indian guy who invested in Virgin Galatic but in the end proved to be rotten? Be careful guys.
Khosla reminds me Spock. Same mannerisms, and same facial structure.

He quit NASA to build a UA-cam channel. Oops, wrong guy.
John what are the posters in your background?
Red flag: not once talking about mitigation of sonic boom. Or did I miss it?
Would love this to be real, but they give me a OceanGate × Nikola vibe.
💯
it sounds like the concept is almost identical to what the Nord 1500 Griffon used....
Did I just see "Airpower" in there 😂

Good. Now SpaceX can fade away into obscurity and Hermeus can take their spot. Thats what I hope, at least.

💀 Imagine this plane getting hijacked... 9/30.....
i guess there will be a higher background verification for traveling in this...
What a fluffy bootstraps story. Really selling it
Never knew i had any interest in this company, in hypersonics, or any of it.... until now. Lol
'the worlds largest bureaucracy ' haha the world's on fire, any body got the VC firm list?
Military application? Yes. Civilian/passenger application? Dont think so. Been there, failed that.
