One of the new designs which may well influence future airplane design is the autogyro. This “flying windmill” in an invention of Senor Cierva of Spain. This queer machine with its huge vanes or sweeps gets off the ground in very short run. The blast of the propeller sets the sweeps to revolving and act as lifting surfaces. The machine can descend almost vertically. The engine is throttled and the machine slowly drifts down the sweeps acting almost as a parachute. The wing only serves to support ailerons.
