ashraf micheal, e-mail, 18.10.2007 21:18 I think the aim of combining the features of A helecopter and a fixed wing aircraft is to have an aeroplane capable of taking off vertically and at the same time have a high forwared speed . This aircraft can successfully take of verically , but the question here is how fast can it fly forwared . the rotor of a helicopter has to give the craft lift and thrust at the same time which poses high stress on the blade ( This the first limit to high speed in helicopters ) . The second limit is that you have to operat the blade at higher angle of attack if you want to increase the forwared speed. Increasing the angle of attack is limited by the angle of stall .
