Rotor for helicopters and model helicopters having controllable backpressure compensation, while at the same time increasing the forward propulsion speed

摘要

A rotor is described for helicopters and model helicopters, in the case of which rotor ram air, which is required specifically in each case, is produced in the rotor region by mechanical and/or electronic control, which ram air not only compensates for the difference in effect between rotor blades which are moving forwards and those which are moving backwards, but at the same time also makes it possible to increase the forward propulsion speed of the helicopter. These technical and design improvements and simplifications, by overcoming the asymmetric backpressure in the rotor region, but especially as a result of the additional capability to increase the forward propulsion speed as well, open up a considerably extended operational capability for helicopters in comparison with powered fixed-wing aircraft.
