AIRCRAFT WITH COAXIAL COUNTER-ROTATING SUSTAINING ROTORS WITHOUT CYCLIC CHANGE OF PITCH EQUIPPED WITH MEANS OF AERODYNAMIC CONTROL OF POSITION AND TRAJECTORY OF FLIGHT

摘要

An aircraft with preferably coaxial counter-rotating sustaining rotors (4,5) comprises in combination: means (21, 27, 24, 25, 29, 34) for variation of the collective pitch, i.e., for applying simultaneously one and the same variation to the incidence of all the blades of said rotors; and means (1, 2, 3) for controlling the attitude and direction of flight, which by generating appropriate aerodynamic forces via the sustaining rotor wind eliminate the need for the presence of means for variation of the cyclic pitch of the blades of the rotors themselves.
