HELICOPTER WITH COUNTER-ROTATING COAXIAL ROTORS WITHOUT CYCLIC VARIATION OF PITCH, EQUIPPED WITH MEANS FOR AERODYNAMIC CONTROL OF ATTITUDE AND FLIGHT PATH

摘要

means 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 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.
