Propeller with self regulated pitch

[ballistic900]

Hello!

Does anyone has information or links about propeller which could adjust the blade angle with own forces acting on blade and change the pitch in the best position?

Thanks;
Michael

Ballistic may be looking for alternatives to the common form of the constant speed prop or the governing mechanism. If that's the case, try first the Patent Office

http://www.uspto.gov/

because many variations of the idea have been tried over the years. Springs, flyweights, hydraulics, pneumatics, electric motors, you name it, I bet it's been tried.
