- In this video we look at 11 high speed VTOL companies that have been selected by USAF to compete for the challenge.
The challenge is to produce an aircraft that can reach speeds of up to 400 knots with VTOL capability. The energy can come from any source - Наука та технологія
i like the ducted fans. Less drag from vortices on the rotor tips and better lift/kw burn ratio than one or two giant rotors.
My money is still on Jetopteras design. I think it suits both the military and non-military requirements. All of the bladed designs are too loud Jetoptera runs ~30Db quieter than their counterparts. And the lack of open bladed fans it is much safer to be near. Theirs is the design that we will eventually see in the skies.
so its 30Db when flying in the air up high? what about taking off and landing sound like?
@@MSaleh-vy8rr That is a great question. I have not seen anything other than what I said here. It would be good to know those sound differences at take-off, but also what about at comparable power output? I don't know what they used for comparison. What I can say, though, is that drones are loud due to the high velocity open blades. With an internal impeller design, there should be a reduction in external noise at any level, wouldn't you agree? Just the physical shielding of the blades should reduce the noise.
Jaunt's slowed rotor compound design is the only option shown that has real world proven potential. The slowed rotor system has been proven with two separate 4-place flying prototypes that reached speeds of over 300 kph and 18,000 ft. R&D on the concept began in 1994 by "Cartercopter LLC".
This channel continues to amaze me with the transition to an all electric economy and transportation system the content is going to be awesome and I can’t wait until most short hop flights are electric as well .
i love your stuff, I feel like i watch it every week it comes out!

Thanks for doing it
I love this channel! Something with so many facts and figures could be really dull, but you manage to keep it so interesting even to someone like me who has no background in engineering or aviation. It would be great if you could add your own subtitles as the automatically generated ones get less of the technical terms than I do
Glad you enjoy it! OK. Good suggestion
Man I have learned so much about fluid dynamics from this channel
Love this video and we need more conversations like this. However, you called the V-22 the “Bell V-22 Osprey” when it should be the “Bell Boeing V-22 Osprey”. Boeing designed half of it an manufactures half of it. There is many good men and women at Boeing who work hard to produce this aircraft that deserve credit. I am only saying this because I know many of those people so I just want to make sure they get credit. Overall you do great work and keep it up!
The slowed-rotor, high aspect-ratio wing design is my favorite. Parachutes notwithstanding, the auto gyro is the best assurance of a safe landing in an emergency. I wouldn't care to fly in many of the other designs. Too much risk. Too little consideration of safety.
True that
Concur.
I've always been confused why autogyros have not become more popular particularly for private owners. Safer to fly than both fixed wing and helicopters and and both easier to learn to fly and simpler in terms of licensure than fixed wing and helicopters. Autogyros should be more inexpensive to purchase and operate than fixed wing, although I havent checked the priced on newest autogyro designs.
@@jpslayermayor9293 , agree with what you say. I've offered to help out the Electric Aviation channel do some design analysis as my masters involved helicopter rotor and fixed wing design analysis. What I already found was that autogyros are slightly less efficient than helicopters at cruise, and this gets worse at low speed. Mostly due to propeller efficiency from reduced air mass flow. And of course autogyros can't hover, which is the main reason that they fell out of commercial use. But electric aviation might offer them a way back as you can design a safe to operate machine with extreme STOL characteristics which typically suits batteries better than VTOL (in my opinion). Put wings on it for high speed and you can unload the rotor to reduce drag. But I think the Jaunt is a powered rotor - they don't give much way on the website.
This is the first that I've heard of this USAF tender. Nice!
The Piaseki design reminds me of the Bell X-22A Ducted Fan Tilt-Wing concept that the US Navy tested for about twenty years before rejecting it for excessive noise from the ducted fans. Helicopter rotors are loud enough, but ducted fans amplify the souynds by a factor of at least three to one, making them fly at triple the noise levels.
Thank you for this overview, Sir !
My pleasure!
Personally, the Guardian hover-jet design was the most interesting to me. Very clean lines.
Same here!
Interesting vid, as usual.
Thanx
My pleasure!
The PA-1459 design looks like it could meet what I imagine would be the military requirements.
Great post my friend. Always very very interesting.
Thank you! Cheers!
Fantastic video as always. The best designs in my opinion are the jetoptera and transcendair… more simple but effective designs.
Glad you like them!
I find Jaunt concept to be the best all around .Being an autogyro, the spinning large prop as it spins at low speed could generate electricity in forward flight. Make it Hybrid with an Achate diesel engine. Less batteries . The props are run on electricity.
Big fan of Jaunt system as variations on the autogiro never really saw their high speed capability realised before. I did like the Sikorsky X2 demonstrator too, although perhaps that concept is not fast enough for this challenge. Low disk loading and plenty of system safety is what you need. Laterally symmetrical tiltrotors are gaining infamy for their tendency for asymmetric vortex ring state accidents when pilots are holding for landings - not good at all.
I have an idea for an electric beetle that I have not seen anywhere else. It uses the airframe combined with distributed propulsion but I have no means to take my idea to the next level :-(
You will have to validate from basic equations that it will be able to fly. You work out engine / motor sizes, total weight with energy system, L/D ratio etc. If it meets the basics, than its a valid design
Build a scale concept model. Say you're thinking a craft that's 40 feet (L) x 20 feet (W). So your model might be 1/5 (8x 4). You can sort out all kinds of issues doing this. You can also do it over a period of time (at your "leisure"). Time-wise & investment-wise. You can also build a cockpit mock-up. Really helps get a handle on the placement/visibility of your essential instrumentation displays. Flight controls. Radio. Good Luck! :)
nice video!
Thanks for the visit
I think Transendair is the best one,. love the accent by the way,. love your works,. can you please do a video on the Jet pack? There seem to be quite a few new developments these days,. would love your insight on Jet packs,. peace Thanks Bless.
Here is a video I did earlier this year
ua-cam.com/video/bQxbmMUijGU/v-deo.html
Excellent stuff bro
Thanks for the visit
This will become an Air Force controlled support asset, if it exceeds the propeller forward powering weapon system (aircraft/helicopter).
I’m surprised you haven’t covered the PteroDynamics VTOL yet. They have a very unique design and working drones.
PteroDynamics will be covered in my up coming video
Bell seems to be the obvious and realistic choice. A Military organization needs to be able to fully trust the material that they are using.
Still, the Guardian Hover Jet looks very promising.
Is it achievable?
Take care and keep it going ✌️
I have my doubt about Guardians VTOL capability
Everything flyes in a screen. Nothing but reality to come true.
Great vid.... Great designs... the footie is now....ish.....
Re-design fighter aircraft like the Harrier jump jet that can hold passengers get rid of rotors, and only use jet engines
Jaunt is my favorite for safety and long range, though not for heavy duty usage.
i like the Lillium! it is great and it is real.
I'm having a hard time reading the knots and km/hour pop-up text. Please consider leaving them on screen for longer in the future 👍🏻
OK sure. Good point
Why you did not included the most advanced and cool one? LILIUM.
Can we have a future video exploring the concept of battery electrifying an already proven VTOL design like the new Cabri G2 helicopter? There seems to be a lot less happening in this space than I would expect. Although far from laminar flow the rotor power does reduce from hover in forward flight, so for sanity check calculation assume 1/2 hover power at 1/2 the stated top speed. Goes up to x2 hover power at stated top speed. Rough numbers but Glauert flow probably beyond what you want to present. I think the range might actually surprise...
I'm pretty busy, but maybe I could generate some numbers or a useful spreadsheet? MSc thesis in helicopter aerodynamics.
Thanks for the tips. Will look into it
@@ElectricAviation , just reached out to you. I've got some spreadsheets I can repurpose to help you generate realistic estimates for performance. I'll deliberately keep them straight forwards, but based on sound principles. I really like the sanity check calculations on this channel. It's what's missing for a lot of projects and will help the best ones to get the investment.
My vote is for Lillium.. . Hold on, they are not in the list??
They cannot do more than 200 knots
@@ElectricAviation maybe at some point they can. not sure if all on the list do more than zero knots.
Because they are real, not just renderers.
I think Joby should be on the list
I think most of these aircraft will not suit the challenge of 400 knots, some attractive proposals such as Jaunts Gyrodyne or Fairey Rotodyne rip would make very successful platforms as we can see by the range, and offer a considerable lift in safety. These machines arent represented because theyre expected to see 400 knots, but they are the opposite of the tilt tip rotor type which I expect will be the first to be discounted due to safety/complexity. The high speed end would be set by the mission profiles considered, and I assume there is a very good grasp of that already, its difficulty is in meeting a speed/range/load solution, and Guardian comes closer to what I would envision here.
Ultimately, the successful configurations are somewhat set in stone, as we already know that the conventional tail tractor has provided us with very good service, so it is true for hovering types being best sufficed by tailrotor helicopter planforms. I would think modest steps from this would suit us all best, so work towards an offset wing Gyrodyne which we already know can service 330 knots +. That said I still want to see that Rotodyne fly
Fluid dynamics
The USAF has not initiated the HSVTOL Challenge to replace the CV22, which it only operates in small numbers and which still have a lot of service life left. This is long-term technical demonstration programme, which means it will piss away a few million dollars to a group of EVOTL startups, then be cancelled with nothing to show at the end.
If you are going to do a comparison with the CH53 family, then surely the CH53K is the correct one to choose?
The military are incredibly conservative. It has taken 30 years for tilt-rotor/tilt-engine to be accepted. It may take another 30 years for EVOTL type aircraft to be accepted.
Fan in wing has been tried before. Its a stupid idea - the wing has to carry around fans that are barely used. This also means you cannot use the wing for energy storage
If you can retractable landing gear , why not retractable VTOL thrusters ?
imagine what revolution in transportation when batteries have the same energy density as gasoline
Delta wing veto transport with two AV eight Harrier jump jet engines
The Valor is already in testing
My design is entirely different,
and should deliver competent results,
if it works.
Please share more when you can! Obviously, bearing in mind any need for non-disclosure of intellectual property. Maybe the tool set I'm pulling together for EA channel can help?
Drone aircraft seamlessly transition by simply tilting the whole aircraft. While some cargo wouldn't have problems, humans don't adapt as well. The real problem with tilt-rotors is their lack of sufficient lift. There's simply not enough margin when lift is 1.1-times aircraft weight. Pilots, especially combat pilots, need a huge margins of excess lift. This author's guess is that a successful design will not involve no tilting or ducting, rather an aircraft that wholly tips up 90° and lands like an Elon Musk reusable booster. Thus, the aircraft will land VTOL on its ass-end. Only in this way can sufficient excess lift be provided for combat ops.
RAJUMOHAN PRESS 💯💯💯💯🌍🇮🇳🇮🇳🇮🇳🙏🙏👌👌👌👍👍
All anyone needs to do, is take the X-19, and modernize it. It had Transmission and 'slow' flight-control-response issues, and, perhaps, weighed too much. All those things are solvable today!
An electric VTOL would be so quiet and advantageous for stealth. The range on that gyroplane is insane! How is that even possible?
look at Lillium
@@stefanweilhartner4415 Lillium is cool but the gyro plane in the video can hold 10+ soldiers so it could be used for stealthily deploying troops closer to target. That’s what impressed me
They can select and reject and project companies all day long. But that doesn’t change any of the basic physics. VTOL is intrinsically energy-intensive and inefficient. You can make somewhat capable vtol drones and camera platforms, but for actual cargo or bombing, not so much. Even the lauded Harrier could not take off straight up with both a full fuel and a full bomb load.
I like ur accent👍👍 r u from india?
No. From Pakistan
Brazlian drone vtol Tupan
Not round enough hehe.
Auto-gyro is good but it lacks the hovering capability of a true helicopter.
Not true. An E-VTOL version has electric motors that power the rotor when needed for full hover capability.
@@rodanderson8490 That would mean that it would be able to change the pitch of the blades.
Bell is the only company who knows what the military wants however with the economy the way it is I think they are all wasting their time.
Bell has the corrupt political connections that will likely get its design selected regardless of performance. I.e. they have the best lobbyist with the most money to donate for political reelection campaigns.
A lot these look like old propeller technology. I was hoping to see something new and innovative.
HORIZON AIRCRAFT and JETOPIERA are the best
If our military is going electric we're fucked
What about battery fires? Those would be fun at 25,000 ft.
Any load reduces range, significantly.
Batteries are too heavy to fly any useful distance.
Fun for hobbies, not practical.
Definitely an important consideration! Typically the risk with fires is in charging, or extreme current draw from say a short circuit. Modern gas sensors are starting to be able to detect the gasses associated with thermal runaway long before it happens. So it becomes a process of good FMEAs a and good testing to minimise the risk or contingencies should it happen. Current generation batteries would allow an e-STOL to do 500km, which would meet my needs for a hobby aircraft! Hopefully some of these calculations can appear on EA channel in future.
🟦 I will admit to being a bit confused about the JAUNT-Mobility Aircraft,....it looks to me to be a vertical-landing craft by virtue of the unpowered rotor, but apparently this craft does NOT possess vertical-takeoff capability!..... Which makes me wonder (& rightly So) WHY it's included in this list?......
Jaunt's design has full VTOL capability. The technology has been fully proven with 2 separate 4-place flying prototypes produced by Cartercopter LLC.
@@rodanderson8490:
🟦 Just looking at the aircraft I'm unable to see any part of it that supports VTO!!.... Is this capability perhaps granted by the rotor being powered during vertical takeoff?....That's the only way I can figure out where it could get lift as I understood from this video that the rotor was UN-Powered!!!?......
My design fly's for 24hrs and carrys 30 people at 600mph
...Not sure if I should call BS or ask to buy shares...
My design flies for 48hrs and carries 60 people at 1200mph

Seem like you need to post the criteria for selection as well as the official Request for Proposal/Requirement....Mixing Apple and Oranges...Is small lift, electrical battery and etc...bunch of non sense?
None of these ideas are going to work especially bell company's design the real working and tech advanced designs are not even revealed to usaf

At 7:13, you messed up the name of respected aircraft builder, PIASECKI.
Why did you do that? Why didn't you fix it during editing?
Why didn't you care enough to do it right?
If you don't care enough to say a name correctly, what other facts are you presenting incorrectly?
Get professional. CARE. Do it right, or don't do it. Sheesh!
I thought you learned this lesson some time back. Learn it again.
They're all junk. My design will scrap all of these next year by necessity since I've decided not to develop in 🇺🇲.
