Quad Cyclocopter Demo

Flight test video of a remote-controlled 25 kg quad cyclocopter.

AVFL graduate student Ramsay Ramsey designed and built this vehicle for his Master's thesis.

Awesome! The "youtube experts" underestimate the difficulty of one of these projects.

A cyclorotor jetpack would be cool to have.

[xchad]

reminds me of a Voith-Schneider propulsion system used in tug boats, ferries, and semi-submersible ocean platforms

[NathanBowman]

Amazing. Would love to see the airflow/wind tunnel on this.

Also, the outer support spokes... Could they be turned into props to further push air to the center? The fuselage could then incorporate structure to redirect air downward.
Just thinking out loud.

It looks self destructive while still being safer for the pilot if it does fly apart.

[Tech_Planet]

Looks good! Wings look like carbon fiber?

[jumpAmonkey]

Great teaching project to show why you don't see these. They're terribly inefficient. Now, modifying an AutoGyro with revolutionary changes that improved efficiency would be a breakthrough.

[selfaware]

Struggled- no payload but good thinking that’s how breakthru’s happen.

[BenjaminGoldberg]

If you had one on each side instead of two, and the diameters were larger, they could run at a lower rpm and would be more efficient.

They would need to counter rotate to avoid creating unwanted roll.

I'm amazed that people are still playing around with this idea nearly 100 years after the first attempt. It's really cool that modern computing allows this type of flight to be possible, but I just can't understand why it's advantageous to add multiple points of failure to an aircraft.

[ColonelKilgore]

nice execution of the cyclorotor concept. on what consideration was 6 blade setup chosen?

[MichaelSkinner-ej]

What about putting a cage around it, like one of those cylindrical caged quad copters? That way you don’t have to worry about bumping into anything and it’s just Smoother?

[donavonlarney]

variable cammed pitch adjustment .... blade top dead centre no thrust pitching as it rotates enclosed in barrels with directional nozzle...

[myperspective]

It almost seems like it could use an act spinning stabilizing gyro.
Maybe placed in a lower position.

[calvinflager]

The noise for extended use, either time or numbers, would be unbearable.

[eCitizen]

It beats the air into submission. Much like the first helicopters did.

[spudnickuk]

No way on earth would I get on that unstable contraption.
And if the owner does then he should get an award.

[Jkauppa]

try ducted shutter directional output impeller instead, you dont have to actively move the blades, just spin the air pump with the shutters in the thrust directions, mostly down

[jeremybowen]

Add fenders to it and it will direct the air flow below it flared open to the rear and more forced air for more forward power,

[AMPProf]

Now Reduce geographic disturbance, cabin vibration and noise
