The clutch might probably be of the pulley type, as used today by Magni, ELA and Auto-Gyro. It's simple, reliable, and the torque transmitted is usually sufficient. The Weir W.3 used a 50-hp engine...

John, attached is my version of your project description form.
Slightly re-worded to allow a bit broader solution spectrum.

John, if your project is using a direct-drive type of motor system, you might want to include a 'recharge' / 'braking' component in the project.
Elaborating: the motor could eliminate the need for a rotor brake (weight reduction to compensate for motor system).

I did add a charging system to the jump-take-off. We will steal it and add it to the pre-rotator.
