Synchropter helicopter.

Is anybody building a synchropter?
Has anybody any technical info on this kind of helo?

I want to know!

Anything new???

New project; ~ ELECTROTOR.

The electric motors are an integral part of the rotorhubs. Rotor
Like all ideas, this has it's pros and cons.

Envision a flying skin that transitions by drooping its foreskin.

This is not a bunch of hot air. It is the Flying Foreskin

Yes we already discussed of that; the problem is located on the battery!...
The best for the moment is to have an electric motor on the tail rotor of a "monorotor" helo as electricity could be drawn from the thermic engine itself!!!(as from an hybride engine...)

Come on André ... there's a huge hole in this "best for the moment" claim based on the power utilization of a heavier than air flying machine vs a car in city traffic. Why aren't hybrids a good choice for long trips on a freeway?

OK OK, Rooter I have to ask, Why did you choose a name like "Flying Foreskin" ?
Made me laugh but probably not the best publicity for something you want ppl to buy. LOL

Larry, i mentioned the hybrid engine to show what could be the generator which could be used to feed the tail electric rotor!...The batteries are used only for short time buffering.
Yes, the hybrid car saves only the energy that you usely waste during all the slowing and braking drive...So, yes, an hybrid car is useless (for savings) if you use it for long highway trip!!! Nevertheless, there are savings which come from the aerodynamic shape of the hybrid car!...
So, I never spoke of an hybrid helicopter...only of generator which could be integrated in the engine...so light enough for the power which could be drawn!...

[quadrirotor]

Dave, there is a lot of energy which is wasted in heat!...the efficiency of the electric engine (at best!) 88%!!! ... generation+motorization=~80%...so 20% of the energy of the engine is wasted in heat...
But you could use electric engine for prerotation as described earlier!

Ranger,

Your'e correct, 'Flying Foreskin' is a little too sexual.

Perhaps 'Flying Carpet', but it may be a little too religious.


Perhaps there is something political.


quadrirotor,

Thanks for the links.

looks like that flyin carpet pilot is experiencing 'light flack'
