Finally, a clip with sound. Another reason why the flying car is only a niche product is the noise ( besides drag and efficiency). Flying cars are a substitute for helicopters, not for cars.
Always been the case. Hovering technology is the only substitute for cars because you'll only need to be a few centimeters off the ground so you can easily go over different surfaces without damage. Flying cars is a fantasy that really isn't that innovative

@@graffiti4christ956 he said it looks like a flying car, thos other ones are just upscaled quadcopters, this one with the diferent propeller look like wheels
Honestly with the purpouse of use on transport that uses traditional propellers, there's no real need to make them quieter. Theres a reason that no manned aircraft has made good use of toroidal propellers or these. Also it means that its limited to being used by drones since it faces perpendicularly to the flow of air so it cannot be used on a 'forward travelling' aircraft like a plane.
Because tip rotor speed is much less, the noise is less high-pitched, which is far less intrusive. It also provides far more responsive thrust control in any direction
@@Fold-103 Not really, if anything making drone based 'flying cars' is a terrible design choice in terms of energy efficiency. Forward travelling aircraft like planes are much more efficient as they use lift and forward motion to keep them in the air whereas you must be using a high rate of power from quad rotors to be able to move slowly. While yes, it makes sense for compact areas where short take off and landings are needed, in any range its better to use a car or train, or take a plane
Could the rotors act as wheels on the ground if rubber was added or if the blade structure was 3D printed similar to the new type of wheels that don't require tubes?
Would be interesting to know some of the specs on this type of rotor, like how much energy is required to make it perform . In what ways might it be better than traditional methods of flight. It's great to see new ideas explored , but are they more practical in every way to what we have now?
Fascinating. Had a question while I was watching - What emergency option would pilots of this kind of aircraft have during loss of power? Without wings in a conventional sense, I don't imagine gliding is possible. Are cyclo-rotors capable of some form of autorotation that would give them unpowered descent capabilities akin to a helicopter? If not, what would the general plan be for operators in the event that the motors failed? Thanks!
Ballistic chute. Ultralight aircraft have them as well. I still think they have to add a wing surface of some sort. The advantage in this case would be the transition to forward flight will become easier.
Besides up and down can it move in other directions, how does it do this? I'm thinking by changing speeds of individual rotors? Also what happens when losing one or more rotors/blades can it auto rotate or glide to safety?
That is the advantage of the cyclogyro concept. It changes pitch of each blade at different times in the overall revolution to instantly vector thrust along any direction in 360 degrees.
Energy lift and mass. How does it stack up? Energy consumption versus mass lifted. Those rotors have a lot more mass than the props used in more common drones. So how much lift are you getting for the amount of energy it takes to spin that much extra mass? I have a feeling it's more of a gimmick than practical.

At least they are honest about the noise - which seems to be not extremely loud. Are the going to develop a larger model for the second test pilot? LOL
Great, you can use this for vertical take off and landing, for traveling purpose gliding is far more efficient. By this technology now you can use your rotors as tyres
Gliding doesn't work in crowded city spaces without large airports. This technology is meant to provide solutions for crowded spaces. Imagine landing spaces in a park near your house and another at your work. You could have aerial buses where your commute is cut in half and pollution is eliminated.
i’m wondering about the wear factor on those blade mounts - constantly rotating at such high rpm? by comparison a helicopter blade hub is under much higher load but very low rpm
Working on magnus effect vehicle for senior design and cant tell you one rotor going outs gonna mean a crash and a hard one at that(hard dive to a corner and flip over). Also definitely requires more power than a standard prop plane of equivalent size bc the rotors have to provide the lift whereas a prop plane the forward motion creates a lift. What I'm curious to see here is how they achieve a somewhat efficient directional motion seeing as the rotors mostly just provide lift.
Like Regenerative Braking in EVs, you should be able to spin the propellers in the opposite direction while grounded to capture wind all day to store in it’s battery for later use.
What are the drawbacks? I’m sure there are some - probably efficiency. A larger propeller without the confines of being in a cylinder must be way more efficient.
I'm curious about the power plant for this machine. I'm guessing that it's electrically powered, but I'm more curious about the weight of this testbed and how much power it takes to get airborne and fly. Unfortunately, I don't work with metric measurements much, so if someone can give me information in Imperial units, I'd very much appreciate it. Thanks! This looks like it could be a very promising technology -- certainly better than the "head trimmer" designs based on more conventional RC VTOL drones.
It is noisy.. possible to make it silent? But it is good... some room for improvement. I am thinking how much energy it needs to use to fly several kilometers. How about under rain and wind? Need safety test.
efficiency??? basically, if aerodynamics is not the main scope one can fly a door with a powerful power motor. Same goes for fancy blades like this one.
I'm skeptical. Flying a light prototype is one thing. Scaling this up to the size and weight for 2-3 passengers is going to be a huge challenge. I expect they will be going for investors based on this prototype.
The ability to change the direction of thrust without turning the propeller is obviously the main scope of the mission. They probably didn’t think that they needed to explain it to anyone
@@Judo-l8d this concept also have spoilers or fins inside that rotating drum and they tilt them also . in this design the fins are parallel to the axis of rotation. i think you have get the whole idea wrong.
I have to admit, to me - it gives the impression of many of the fancy early airplane prototypes. Where innovators had gone at length in a certain design direction - and against conventions. I am not an expert or engineer, but I seriously doubt this propulsion design will be standard. Rotors in some sort of gyro suspension just seems more logical, safe abd with better maneuverability.
If you put a tyre on the rotors you could drive it on the road after you landed perhaps incorporating u the rotor adjustment mechanism for damper/suspension.
Unfortunately, there are few who work fruitfully in this direction. But the fact that this team is working on creating a cyclogyro even according to the old aerodynamic design of 1909 is also very cool!
Remarkable! It’s about time somebody took aviation to the next level. (Sikorski was treated as a crackpot when he developed the helicopter. History repeats itself, right?)
Dr Ignaz Semmelweis was also considered insane for suggesting washing your hands before delivering a baby would reduce infections. This is a cornerstone in multiple industries today.

Cool. Moving around in 3D like in "The Fifth Element" is near.
These rotors have been used in vertical axes wind mills for at least 50 years... but because the paddles basically only derived force from reaction they could not get above a theoretical efficiency of around 40%, where as an aerodynamic propeller harnesses bother reaction and impulse from lift created by the blade shape, in theory up to 80% efficient. I would be interested to see efficiency comparisons between your rotor energy consumption per volume of air moved compared to a well designed propeller, after all if energy limitations did not exist many more things would be made to fly!
Check out the first flight of the CycloTech technology demonstrator. The Austrian company based its "CycloRotor" propulsion system on the Voith Schneider Propeller design, which has been used in maritime applications for decades.

so why is nobody sitting on top of this ? as kids we used to have kites hat worked on the same principle with light plastic wings made with two rotating leaves . hey were noisy too!
these fan are very noicy.. but a good concept. would love if that also could be used to windpower house (in reverce mode). duing night time there the sun is down and solar do not work.

Im not a mechanical engineer... also differential torque would cause it to nose up or down...? im a software guy im just curious what code would look like to control these surfaces. I think it would also have issues banking and with yaw. Pretty cool looking.

I think the propeller idea is cool and it looks safer than swinging a giant sword around
Except when the engine goes out you can land that giant sword with auto rotation, while this falls like a brick.
And Rotors at the height of a human are obviously more dangerous than a „giant sword“ rotating way above your head
when you fold up the prop, could you turn the cyclorotor like a tire so that it can run on the road as well?
Smooth landing !
Those rotors are already safer for people around, just looking a the shape they have.
Congratulations to the team!!!
Great, you can use this for vertical take off and landing, for traveling purpose gliding is far more efficient.

What are the drawbacks? I’m sure there are some - probably efficiency. A larger propeller without the confines of being in a cylinder must be way more efficient.
These are better and safer than propellers.
How does it do yaw control?
For military aircraft, you would need barrels that are bigger and longer, that way they can bite/ displace more air
I assume the blades could be semi hidden with screens that would allow air flow but act as a guard.

If you lose one spool, the fall will be immediate. By reducing the wing length, noise increases. It is unlikely that the development will reach civilian use
Actually if three of the wheels are strong enough it could technically stay up. Unlike a quadcopter.
If by lose one spool you mean one motor on one rotor breaks, there's an easy way to mitigate that risk.
Simply link the rotors together with axels to a single motor (or tandem motors for redundancy) and a drive shaft with a transfer case like an AWD car
Next step, hide the rotors inside the frame and you have a futuristic flying car with no wings or visible propellers. F35 vtol style
