Custom Clutch for 80 kg Radial UAS

Hi Guys,

I am currently doing a final year aerospace engineering project at Carleton University and need some help designing a clutch for our drive system. It is a rotorcraft unmanned aerial system with a main rotor diameter of 3 meters. The engine we are using is the Moki 400 radial ~ 25 hp, idle at 600 rpm and max rpm of 3800.

For the clutch, I need it to begin to engage around 1000 rpm and am wondering if anyone has experience with the sizing and overall design. How large of a diameter should the clutch be? How thick?

Is there a commercial solution available on the market right now? I have done a lot of research and haven't found anything capable of this scale.

Any insight is appreciated!

Don't really know, but the first thing that crossed my mind was a clutch from one of the larger atv's. Good luck with your project. Ed
