Propellors
(OP)
I'm looking for information on any types of experimental propellers/propeller systems. Hybrids, fans what ever.Thanks in advance

RE: Propellors
My concept was actually designed to be an ultralight type aircraft with a max gros of about 500lbs. It was basically a flying wing (lifting body) with a vectorable ducted fan that was not designed to actually hover, but could possibly be hovered in a light to moderate headwind. (I called it accellerated hover.)
If you aren't looking for speed, a large diameter ducted fan (prop) is capable of producing a large amount of static thrust out of a relatively small engine and can be lighter than a rotorcraft because you don't usually need a reduction gearbox. The only problem is that the duct that helps you create all that static thrust is going to be very draggy at high speed.
It just depends on how fast you want it to go, how much takeoff room you have, and how badly you need it to hover. Hovering is the hardest part of vertical flight. If you can get away with a very short take-off and landing with the ability to hover in a headwind I can show you something interesting. Mike C.

Contact me at micallahan@worldnet.att.net and I'll try to get you some rough drawings and digital pics of the 3'x4' 1:4 scale R/C model I built. I never flew the model, but I built a 12"x14" 1:12 glider with the duct and same basic geometry and it flew great. Mike C.
