would this work or been done?

just wondering

To what extent would you expect this scenario to work?

There is a reason why the airfoil changes between two different types of aircraft.

It MIGHT work at a given speed and altitude but realistically NO.

Simply attaching a gyro rotor system on a helicopter won't work because of basic design issues.

Tim,

Chuck Beaty would be the one to ask, but I recall that when Ernie put a set of DW's on a Mini500, Chuck mentioned that he had to reinforce the blade roots and straps. A regular hub setup would have failed from the torque being applied.

Gyro rotors and hubs are not meant to be driven from the root end.

Animal,
Dragon Wings are standard on the Mosquito Ultralight helicopter. There are a few differences, but the airfoil is the same.

thats what I thought I had read somewhere before. but yeah I can see where they would have to be mounted with straps and not to the hub like on a gyro. I know the airfoil will work,as rotorway has offered both styles of airfoils, but I was not sure if you could adapt a gyro hub bar type mount to a trape type mounted Rotorhead.

AS you can see, with the blades mounted to a head like from the Choppy as shown, you have to either remove a bunch of bolts, or remove straps and all. if you remove the straps, you lose all you tracking adjustemts. not a good thing.

Don't worry I am not thinking of a Choopy head, way to small for my needs. just used it's pic so you could see the way the straps mount.
The mount is one main difference. They also have a bigger root doubler,larger tip weights, and no twist. They are also shorter.

I guess I wasnt clear.

A rotor system needs to be designed for the application. This would include the physical shape. Disk loading and strength would be taken into consideration.

So that being said. Airfoil, length, twist (if any), tip weight, and articulation would be factors.

Airfoil: Should be a zero moment airfoil

Articulation: It needs to have the capacity to pitch up and down. Lead lag, flap, feather, etc.

Can you make a gyro blade work on a helicopter? Sure. Can you strap a set of Dragon Wings on a Jet Ranger? No.
