How can you have laminar flow when you need highly compress air jet mixing with ambient air to generate flow induction? This is nonsense they are just stringing together buzzwords to fool investors.

Unless I am mistaken the entrainment function merely uses a small high speed stream to accelerate a larger low speed stream, but it does not create any additional thrust. It is hard to see how this could be more efficient than a propelller driven plane, as the propeller directly creates a low speed stream without needing to accelerate the air around it.
That's why they cleverly don't claim that. If you listen carefully they claim to be superior to small jets system. I imagine it's pointing to small ducted fans like E-fan airbus electric plane, or small turbo jets. Not propellers. The entrainment causes more flow around the motor so more lift for the box. I think it's a good compromise of compacity and efficiency and safety against multirotors or tilting multirotor + small wings.
Maybe sometime someone makes this effect into the wing itself so the whole surface is both propulsion and lift. Also this plane has a rather small intake at the top, this might be the limiting factor for its total power.
Actually, entrainment experiments 100 years ago in Scotland using solid rockets to give the core gas stream, showed a thrust amplification of around ten. The idea is to tailor the exit speed of the mixed flow so that it leaves the rear of the aircraft at exactly the same speed that the aircraft is moving forward: thus, the exiting flow leaves with zero speed relative to the atmosphere so has zero wasted kinetic energy remaining in the exhaust. Ergo, big improvement in efficiency.
Simple and elegant... hopefully it will work and come to market soon. That bladeless propulsion looks like magic to me. What amazing minds to discover this technology. BRILLIANT!
Great video, I look forward to hearing more about this concept. The idea of a more simple VITOL craft is needed. The viability of the small electric craft makes it quite interesting and makes it more financially viable. I really hope this development works. It is easy for those with a negative mind to sit there and say it won't work, but developers like this need as much encouragement as possible...... Keep going Jetoptera!
I'd like to see the calculations for their propulsive efficiency. There may be an augmentation effect (similar to ejector pumps as you pointed out) but the efficiency of the gas generator must also be factored in.
It's nice too see them doing what I had wondered about. Using 'blade-less' lifter engines. I think they will stand well for low velocity cruiser aircraft.

This same principle is used by some camping beds and beach couches where you gently blow into the inflation tube which is specially designed to multiply the air, and it blows up the whole couch. Your breath creates a pressure difference and a flow which pulls in the surrounding air to fill the entire thing with very few breaths. Pretty cool. That’s just a simple way to see this principle in action with your hands and your own breath. It’s pretty magical when b you see it work! One breath and the bed is almost full! It’s pretty crazy… science is awesome

He showed similarities between a Copus blower and Henri Coanda's air foil aircraft design, to this design. both operate similar to how the Dyson blower works. Copus blowers have been used for years for confined tank enclosures and for drying or cooling inside of tanks. We used ours to cool down the shaft furnace at our copper refinery just before a furnace rebuild.

These thrusters rely on turbulent mixing of the driving jet with the secondary airflow. They can not enhance thrust over the entire flight regime - maybe they can enhance static thrust. I am sceptic.
I think this is an amazing exercise in thought and I wish them all the luck. The design is very close to what I am trying to accomplish myself. I am very excited to watch their progress and very thankful that the time and money isn't mine wasted in this pursuit. I almost certainly guarantee that they will find that these principles do not apply and are very ineffective at scale to lift something vertically like a passenger vtol. But that being said I pray I am incorrect. And if anyone reading this associated with this project I would be interested in offering my game changing energy storage systems.
F4E Phantom used blown leading edge flaps. Lowered take off and landing speed by 15-20 kts. Used lots of compressed air but J79 had plenty to serve up.
In these VTOL 'demonstrations', did they actually match the scaled weight and weight distribution modeled for a unit equipped with a gas turbine and fuel against the scale adjusted thrust expected from said turbine system? Because I can strap a single LiPo battery and enough high power ducted electric fans to a toilet, and burn through the LiPo's power to get it in the air for 20 seconds, but that doesn't mean a toilet is a valid aircraft, jet engine or not.
Often "startup" companies do just that. Feed you some serious 'crap' while getting a crap idea to partially demonstrate, then fleece dumb investors, flounder, and act like they don't know what happened with the 'new technology' not working out. Oh yeah, all while the founders make millions on failed ideas.
@@life_of_riley88 And fanboys keep drumming the thing further. Like with this video, hey look electric flying car! It can easily be made electric... when battery technology advances further.. so not in several decades and i would be even less interested in this flying coffin than EV, since with EV you wont probably... maybe die when batteries crap out.. with this yeah no.. With jet engine this might have some sense, but vtol is always hard thing to build since you need lots of computers to assist even professional pilot.. One computer crapping out can easily lead disaster with vtol. Also as mentioned duckted fans are now flying the test platform, but we have no idea what ever this actually works in real world aircraft and will it be powerful and practical enough. Its interesting concept, just hate how EV fanboys start drumming for shit like this, even before there is model version flying and even then scaled weight of the aircraft seems to be forgotten on test for looks of it.
@@Hellsong89 What do you mean "like with this video"? The video is fairly informational and doesn't act like the technology is right around the corner. The guy isn't drumming anything up. I get how annoying the current tech climate is with people like Musk and his cult but that doesn't make it a good idea to take the polar opposite stance. Yes, the technology is being looked into. That's all the video really says while breaking it down into examples how how the tech is used today as well as proofs of concept in the past. Nothing wrong with taking a look at previously mothballed technology with a fresh pair of eyes as long as no one's being conned, which this video doesn't appear to be attempting to do.
@@bikebrains another person posed the idea of making a smaller bladeless system for a boat, imagine a bunch of STEM students designing, printing and using a system like that on a kayak via 3d printing.
One huge advantage of this concept for application to flying cars and urban air mobility is the lack of exposed rotors/propellers. Designs like the Ehang 216, for example, feature exposed rotors that are hazardous to life and limb, limiting flexibility for boarding, and operations around people.
Without question, this technology will revolutionize every day travel. Wishing you great success with this project. Hopefully in the near future people will be transported using a clean, non carbon based furel systems.
I'm interested to know how exactly entaining more air through the rear cowl actually results in more thrust, or even more air flow over the wings, since it looks like the air will be entrained through the cowl father than around it, and any air flow at the back looks like it will be behind the wings altogether.
One reason is that the wings can be laminar flow with no engine cowlings interfering with airflow over the surfaces, in addition the intake of air increases the flow over the wings, creating more lift.
@@scotthill2230 but how does the intake increase the air over the wings? I would get it if the cowl inlet started behind the wings, or if it finished in front of the wings, but I really can't see how its meant to be moving any more over the wings at all.
@@benwilms3942 Wouldn't the accelerated air that's rushing back create an area of lower air pressure in front of the cowl causing the air in front to get sucked in and accelerate over the wings in the process?
@@benwilms3942 The thrust provides forward movement, which in turn provides faster and faster flow of air over the wing as the ground/air speed increases. The wings themselves passively provide lift by virtue of their shape. Therefore it matters not what airflow is produced behind the wings by entrainment, other than to provide thrust for forward movement.
Many technologies have been out for many years but we just couldn't make them into a viable product due to our limited understanding. Once the right breakthrough is achieved and financial backing is secured can it materialize to something. Note that this can happen multiple times until said product is commercially viable. (VR comes to mind). We see this in science too. We're aware of quantum physics for a hundred years and our most brilliant minds have been working on it since, yet this is still the case: "If you think you understand quantum mechanics, you don't understand quantum mechanics."
@@635574 Yep going with your average football shaped blimp with a large propulsion ring right around the mid section, or perhaps slightly toward the back to reduce drag. Would love to see how it performs in a computer simulation
This is the 'cleanest' propulsion system I've seen. The e-aircraft with zillions of often vertical facing 'propellers' simply look chaotic. And each propellor unit needs a motor thus upping the cost and potential reliability. This system, on the other hand, is relatively simple, and, I've read, quiet. It looks much better than the Cityhawk thing too. I hope it gets made.
Fully agree. If this "multiplies flow", then just route the output of one such "jet" back into itself, or through a chain of them, and voila - infinite energy. This might be just another of those beautifully-rendered graphics presentation.
@@markozagar The catch to that, in practice, is that flow multiplication relies on high pressure at the intake, and low pressure at the output. If you create a circular chain of these, then taking an arbitrary start/end point along the circle, the pressure will be LOWER at the intake of your "start" point than at the outlet, because the pressure will consistently drop across each propulsor in the loop. Kinda like the time zones need to reset at the International Date Line because they can't keep going backwards forever. So the physics of the idea is sound, but putting them in a loop to create infinite energy is not.
@@markozagar The issue is that this kind of device is great for moving air around a room and for propelling a model aircraft, but the physics does not scale up very well. Doing something like this for propulsion of an aircraft that can carry a person would use way more power than a conventional propeller that's electrically driven. I just cannot see something like this being efficient enough to knock other modes of propulsion of their throne.
The box wing concept was used in the Synergy aircraft design that looked promising a few years ago, but its development doesn't seem to have gone anywhere recently. Hopefully the Jetoptera design will be able to take this idea forward to something realisable at full scale.
That is too cool! I bet it's going to be extremely quiet compared to a standard jet engine. And you're really good at explaining it all. You've got a new subscriber
As much as I like him debunking stuff, dude has a big hate boner with alright projects like from TESLA and SpaceX. Otherwise, he's an alright skeptic. It just gets annoying when he does it again and again.
@@RandomnessCreates i stopped watching the dude years ago because hed make the video after video on the same idea with slightly different words or order of pictures. not only that, but he would repeat the same point 4 times in a single video.
Yeah we will just encircle the sun with dyson sphere panels then transmit power to air vehicles... energy density problem solved ! Should be up an running any time now....lol
anything will work on batteries if the energy density is high enough! Even then I still think other ways of generating thrust are more efficient than Jetoptera's claims.
This is absolutely AMAZING. We are living in incredible times. We are looking at this technology I'm sure the way the wright brothers looked at the technology they crafted. I'm so excited to see the future. 👍👍
"bladeless" - except for all the blades in the compressor feeding this system..........It seems nobody ever learns from history. The Americans and Canadians found that the "coanda effect" doesn't scale up to aircraft size after spending millions of dollars.
this IS coanda effect obviously, and im NOT seeing any benefit from this particular configuration. If it was integrated into the wing chord for added lift it would make more sense.
The model at least seems to be flight worthy. And there are already aircraft using the exact same transition method, albeit with classic jet or prop engines. It really only depends on being able to generate enough forward thrust to reach sufficient aerodynamic lift through airspeed before losing vertical lifting capabilities.
@@kalliste23 I agree that it is all but trivial. But the principle has been proven to work in certain aircraft already in use (e.g. Osprey or other tilt-rotor-aircraft). That doesn't make development of this concept any easier, but it shows it could be done.
@@JescoLincke Osprey is a good example - go back and check out the history of the development of the Osprey and the mind boggling amount of money that involved.
I have been flying Electric RC, planes, both propeller and ducted Jets, Helicopter’s for about 20 years. My buddy Matt flys Turbine jets. Very fast and cool, but the cost is way more than I would like to afford. This is very interesting, subbing.
I love this. Please stop talking about flying cars. You dont want one. Go fly an airplane some, and understand, one cant pull over if there is a problem. So the reliability MUST be very high. Cars breakdown all the time. You never want an airplane to break down.
William Pierce It seems like people don’t really give these kinds of things a lot of critical thought. They just fall in love with the idea & stop right there..
The canard and the front fans need to integrated into one design, I am sure the front fans could act as canards without the complication of being stowed.
No, the problem is, once they stop producing the thrust for VTOL, any sort of open ended tube like that (of almost any cross section and wall profile) will then produce a tremendous amount of drag. In fact it usually produces more drag as an open tube than it would, were the opening completely capped (a solid profile from the front).
Surely I'm not the only person who's noticed they're "successful" flying model is using simple in-housed fans? "Our engines work! See how these normal fans lift our prototype airframe? There you have it!"
@@plvmbvm513 Got no problem with that. My problem is the backbone of their business model is their engine, and not every investor or creditor might get that a successful airframe doesn't mean successful capture of their target market. Not saying these guys are frauds, just saying this is how ARCAspace's flight of the aerospike and Nikola's hydrogen trucks fleeced their backers.
Interesting concept, I wonder if this could be applied to boats, with an electric fan. I’m thinking particularly to the small dingy and kayak/ trolling sectors where hands and animals proliferate.
That is actually a very good idea. I am sure people looking at submarine propulsion would be extremely interested and even boats

Pump-jet on watercraft have quite a few similarities.
Tom Clancy wrote about such a submarine drive in The Hunt for Red October, in the 80's.
It will be interesting to see how the thrust-to-weight ratio works out for the full-scale, manned and fully-equipped aircraft.

Exceptional video! I've never seen this channel until today, but was elated to find that although you have an accent the content was very good. I've seen people with accents believe they can never do things like RUclips because of it, but I think videos like yours are proof that it's all about the quality of the content.

As a sub contract industrial designer in Calgary I had a brief pleasure of working on a few components of Apteras electric car. It also uses Laminar surface tech, The look is very much of the same designers so I'm betting heavily its the same visionaries. Congratulations and I hope your strategy for business gets you there faster, into your rightful place in history. First place conceptually.
He showed similarities between a Copus blower and Henri Coanda's air foil aircraft design, to this design. both operate similar to how the Dyson blower works. Copus blowers have been used for years for confined tank enclosures and for drying or cooling inside of tanks. We used ours to cool down the shaft furnace at our copper refinery just before a furnace rebuild.

These thrusters rely on turbulent mixing of the driving jet with the secondary airflow. They can not enhance thrust over the entire flight regime - maybe they can enhance static thrust. I am sceptic.
it is supposedly meant to increase lift on the wings... at least that's what it looks like to me.
Just a picky note: you meant "skeptic". Sceptic means a blood infection.
@@2degucitas maybe thats what he meant, maybe he has a blood infection

@@doctor_moodm9536 Which makes the cartoon of using them as VTOL lifters dodgy.
I think this is an amazing exercise in thought and I wish them all the luck. The design is very close to what I am trying to accomplish myself. I am very excited to watch their progress and very thankful that the time and money isn't mine wasted in this pursuit. I almost certainly guarantee that they will find that these principles do not apply and are very ineffective at scale to lift something vertically like a passenger vtol. But that being said I pray I am incorrect. And if anyone reading this associated with this project I would be interested in offering my game changing energy storage systems.
It's like a cross between a Hawker Siddeley Harrier and the Red Baron's Triplane!
This is one of the coolest videos I have ever watched on RUclips...
So I take it you have never seen many youtube videos
A concept that may become a landmark to aviation. Interesting. Keep it up.
So where can I invest in this unproven tech based on a novelty fan? Cause flying cars are a good idea.
😏
flying cars are a terrible idea: the sky will soon be as overcrowded as the roads are now.
we need flying busses, trains,...
@@darkswami Lol its crowded because you are limited to roads. No lanes in the sky...
Flying cars have existed for over 100 years. They are called airplanes.
@@darkswami flying busses already crowd the skies. They are called jumbo jets
F4E Phantom used blown leading edge flaps. Lowered take off and landing speed by 15-20 kts. Used lots of compressed air but J79 had plenty to serve up.
shinmawa US2 stol seaplane , also uses a turbine for force assist flow over flaps ,
Those systems were low airspeed lift augmentation designs and horribly inefficient. They did their job, though.
Your explanation of the principle of operation of this aircraft is underrated, keep up the good work
In these VTOL 'demonstrations', did they actually match the scaled weight and weight distribution modeled for a unit equipped with a gas turbine and fuel against the scale adjusted thrust expected from said turbine system?
Because I can strap a single LiPo battery and enough high power ducted electric fans to a toilet, and burn through the LiPo's power to get it in the air for 20 seconds, but that doesn't mean a toilet is a valid aircraft, jet engine or not.
Often "startup" companies do just that. Feed you some serious 'crap' while getting a crap idea to partially demonstrate, then fleece dumb investors, flounder, and act like they don't know what happened with the 'new technology' not working out. Oh yeah, all while the founders make millions on failed ideas.
Sounds like a crappy way to travel.
@@life_of_riley88 And fanboys keep drumming the thing further. Like with this video, hey look electric flying car! It can easily be made electric... when battery technology advances further.. so not in several decades and i would be even less interested in this flying coffin than EV, since with EV you wont probably... maybe die when batteries crap out.. with this yeah no.. With jet engine this might have some sense, but vtol is always hard thing to build since you need lots of computers to assist even professional pilot.. One computer crapping out can easily lead disaster with vtol. Also as mentioned duckted fans are now flying the test platform, but we have no idea what ever this actually works in real world aircraft and will it be powerful and practical enough. Its interesting concept, just hate how EV fanboys start drumming for shit like this, even before there is model version flying and even then scaled weight of the aircraft seems to be forgotten on test for looks of it.
@@life_of_riley88 Tesla being one of the best modern examples of this lmao
@@Hellsong89 What do you mean "like with this video"? The video is fairly informational and doesn't act like the technology is right around the corner. The guy isn't drumming anything up.
I get how annoying the current tech climate is with people like Musk and his cult but that doesn't make it a good idea to take the polar opposite stance.
Yes, the technology is being looked into. That's all the video really says while breaking it down into examples how how the tech is used today as well as proofs of concept in the past. Nothing wrong with taking a look at previously mothballed technology with a fresh pair of eyes as long as no one's being conned, which this video doesn't appear to be attempting to do.
Great presentation. I learned a lot from your video. For the technology itself, this is huge. It looks to me like a future of flying.
This video should be sent to all STEM schools. The WOW factor could inspire students to study physics and a variety of engineering subjects.
@@bikebrains another person posed the idea of making a smaller bladeless system for a boat, imagine a bunch of STEM students designing, printing and using a system like that on a kayak via 3d printing.
@@bikebrains To learn how not to do it?
So much like the dyson bladeless fan, it uses more blades than a traditional fan, cool
One huge advantage of this concept for application to flying cars and urban air mobility is the lack of exposed rotors/propellers. Designs like the Ehang 216, for example, feature exposed rotors that are hazardous to life and limb, limiting flexibility for boarding, and operations around people.
This is an absolutely brilliant concept I really hope they can get this thing going with a full scale mock-up
Without question, this technology will revolutionize every day travel. Wishing you great success with this project. Hopefully in the near future people will be transported using a clean, non carbon based furel systems.
this channel is so well researched. great to watch
Much appreciated!
What !!!!
I'm interested to know how exactly entaining more air through the rear cowl actually results in more thrust, or even more air flow over the wings, since it looks like the air will be entrained through the cowl father than around it, and any air flow at the back looks like it will be behind the wings altogether.
One reason is that the wings can be laminar flow with no engine cowlings interfering with airflow over the surfaces, in addition the intake of air increases the flow over the wings, creating more lift.
@@scotthill2230 but how does the intake increase the air over the wings? I would get it if the cowl inlet started behind the wings, or if it finished in front of the wings, but I really can't see how its meant to be moving any more over the wings at all.
@@benwilms3942 Wouldn't the accelerated air that's rushing back create an area of lower air pressure in front of the cowl causing the air in front to get sucked in and accelerate over the wings in the process?
@@bokiNYC im not sure I follow, if the air is moving into the cowl, then I can't see the connection with air moving over the wings.
@@benwilms3942 The thrust provides forward movement, which in turn provides faster and faster flow of air over the wing as the ground/air speed increases. The wings themselves passively provide lift by virtue of their shape. Therefore it matters not what airflow is produced behind the wings by entrainment, other than to provide thrust for forward movement.
Great level of detail on your explanations, great to see someone actually go beyond the superficial marketing blah blah!
Much appreciated!
"There's nothing new under the sun." This was used years ago in the 50s with Jetex model rocket engines fitted with an augmeter tube.

Henri Coanda build the first UFO and he call it:
AerodineLenticulare .
Many technologies have been out for many years but we just couldn't make them into a viable product due to our limited understanding. Once the right breakthrough is achieved and financial backing is secured can it materialize to something. Note that this can happen multiple times until said product is commercially viable. (VR comes to mind).
We see this in science too. We're aware of quantum physics for a hundred years and our most brilliant minds have been working on it since, yet this is still the case: "If you think you understand quantum mechanics, you don't understand quantum mechanics."

@@geoffnottage8894 perhaps a point on Jetex fuel - it used Nitroguanidine, made from bat shit and nitric acid, if I remember right
I'd love to see what this type of propulsion could do wrapped around a blimps mid section
turtleairships has the same interest in the potential.....
I would be more interested in ridged airship applications, although without wings they would operate as thrusters. Perhaps an azipod for dirigibles ?
Do you mean the whole surface could propel it? Nice idea
Supersonic stealth blimp confirmed!
@@635574 Yep going with your average football shaped blimp with a large propulsion ring right around the mid section, or perhaps slightly toward the back to reduce drag. Would love to see how it performs in a computer simulation
Wonderfully explained. Such a calm and scientific manner of presentation 🙏🏾🙏🏾😌
Really well explained , thank you!
This is the 'cleanest' propulsion system I've seen. The e-aircraft with zillions of often vertical facing 'propellers' simply look chaotic. And each propellor unit needs a motor thus upping the cost and potential reliability. This system, on the other hand, is relatively simple, and, I've read, quiet. It looks much better than the Cityhawk thing too. I hope it gets made.
Needs lots of investors
Very well explained, with good visuals of how it works. Thank you for the information.
We need to bring Thunderf00t's attention to this.

@@DartTyler Biggest red flag
Fully agree. If this "multiplies flow", then just route the output of one such "jet" back into itself, or through a chain of them, and voila - infinite energy. This might be just another of those beautifully-rendered graphics presentation.
@@markozagar The catch to that, in practice, is that flow multiplication relies on high pressure at the intake, and low pressure at the output. If you create a circular chain of these, then taking an arbitrary start/end point along the circle, the pressure will be LOWER at the intake of your "start" point than at the outlet, because the pressure will consistently drop across each propulsor in the loop. Kinda like the time zones need to reset at the International Date Line because they can't keep going backwards forever.
So the physics of the idea is sound, but putting them in a loop to create infinite energy is not.
@@markozagar The issue is that this kind of device is great for moving air around a room and for propelling a model aircraft, but the physics does not scale up very well. Doing something like this for propulsion of an aircraft that can carry a person would use way more power than a conventional propeller that's electrically driven. I just cannot see something like this being efficient enough to knock other modes of propulsion of their throne.
Nice video! It would be interesting to see how performance changes with altitude.
6:26: this video Gets a LOVE. I don't get the principle behind it, but VT without visible downward facing thrusy just blew my mind.
I love this so much. I'm stoked to have found your channel!
Very interesting! *:D*
*I have a question:* _What is the noise level of this "Bladeless" technology?_
Inside the plane, with the motor in there, I'll bet it makes one hell of a scream, outside pretty quiet.
What's the noise from a Dyson room fan compared to one with blades ?
Thank you for sharing your concepts and explaining them so well. I hope you get somewhere with this.
I hope so too!
i was thinking about this last couple of week. it's like RUclips algorithm is in my brain.
The box wing concept was used in the Synergy aircraft design that looked promising a few years ago, but its development doesn't seem to have gone anywhere recently. Hopefully the Jetoptera design will be able to take this idea forward to something realisable at full scale.
Yes, I keep looking for progress on the Synergy. From what I can tell, it's a father and sons endeavor.
This is the Most Exciting Futuristic Airplane Design I have seen yet, it seems to have so much going for it. these Designers are so smart 🤓.
That is too cool! I bet it's going to be extremely quiet compared to a standard jet engine. And you're really good at explaining it all. You've got a new subscriber
Dyson bladeless fans are louder than cheap fans.
Dyson claims 60-70% nose reduction for their fans vs. Blades
@@myotherusername9224 at minimum speed vs blade fans at maximum. When full fledged they're noisy AF and don't even blow that much air
Amazing video as always. Really loving this channel! Keep up the great work!
Thanks, will do!
It will be extremely interesting to watch the development of this idea
In fact, this is a type of ejector. Ejector's efficiency is poor. And with high passive flow to active flow ratio it is poor twice.
poor twice sounds like my financial condition
But.... don't 2 negatives make a positive? 🤣🤣
@@rosebarnes9625 twice is a positive number.

"Once the required energy density becomes available"

Yeah we will just encircle the sun with dyson sphere panels then transmit power to air vehicles... energy density problem solved ! Should be up an running any time now....lol
We'll have hover tanks once the energy density problem is solved.
anything will work on batteries if the energy density is high enough! Even then I still think other ways of generating thrust are more efficient than Jetoptera's claims.
Great! Now I just need to watch it 10 more times to understand it...

"bladeless" - except for all the blades in the compressor feeding this system..........It seems nobody ever learns from history. The Americans and Canadians found that the "coanda effect" doesn't scale up to aircraft size after spending millions of dollars.
60 years ago - maybe they have solved the issues.
@@daviddesjardins7751 those guys 60 years ago pretty much reached the physical limits of what is possible in regards to jets.
What are you talking about? I’m interested in learning. (:
The Avro Car? the US took it all from Avro and it went black so we on't know where it ended up.
this IS coanda effect obviously, and im NOT seeing any benefit from this particular configuration.
If it was integrated into the wing chord for added lift it would make more sense.
This all looks lovely in CGI but back in the real world these fall down when transitioning between flight modes.
It's still cool, if they are improving their design and working out the kinks
Even if in this case the kink is falling out of the sky
The model at least seems to be flight worthy. And there are already aircraft using the exact same transition method, albeit with classic jet or prop engines. It really only depends on being able to generate enough forward thrust to reach sufficient aerodynamic lift through airspeed before losing vertical lifting capabilities.
@@JescoLincke the transition is easy to do in CGI, or in a sentence, but it has to happen reliably in the real world. It is not a trivial problem.
@@kalliste23 I agree that it is all but trivial. But the principle has been proven to work in certain aircraft already in use (e.g. Osprey or other tilt-rotor-aircraft). That doesn't make development of this concept any easier, but it shows it could be done.
@@JescoLincke Osprey is a good example - go back and check out the history of the development of the Osprey and the mind boggling amount of money that involved.

I love this. Please stop talking about flying cars. You dont want one. Go fly an airplane some, and understand, one cant pull over if there is a problem. So the reliability MUST be very high. Cars breakdown all the time. You never want an airplane to break down.

Thank you, this was so interesting.
“I’m a ‘bladeless fan.’ Except I have blades.” Brilliant!
extremely informative video; thank you! New sub from me!
The canard and the front fans need to integrated into one design, I am sure the front fans could act as canards without the complication of being stowed.
No, the problem is, once they stop producing the thrust for VTOL, any sort of open ended tube like that (of almost any cross section and wall profile) will then produce a tremendous amount of drag. In fact it usually produces more drag as an open tube than it would, were the opening completely capped (a solid profile from the front).
@@daemn42 I'm wondering how they are powered. If by, say a PT6, then I hope they are cooled in the airstream prior to being stowed!
I like this design above all the others I have seen so far. It looks very promising.
Surely I'm not the only person who's noticed they're "successful" flying model is using simple in-housed fans?
"Our engines work! See how these normal fans lift our prototype airframe? There you have it!"
It doesn't seem that strange to test the airframe first and then worry about switching engines
@@plvmbvm513 Got no problem with that. My problem is the backbone of their business model is their engine, and not every investor or creditor might get that a successful airframe doesn't mean successful capture of their target market. Not saying these guys are frauds, just saying this is how ARCAspace's flight of the aerospike and Nikola's hydrogen trucks fleeced their backers.
I'm genuinely surprised at the quality of the video, great job!
