HYBRID HELICOPTER INCLUDING INCLINED PROPULSION PROPELLERS

The present invention relates to a hybrid helicopter comprising a fuselage, a main rotor, two wings situated on either side of said fuselage, and two propulsion propellers situated respectively on each wing. Each propulsion propeller is inclined, and when it rotates it generates a thrust force (Fd,...

description	The present invention relates to a hybrid helicopter comprising a fuselage, a main rotor, two wings situated on either side of said fuselage, and two propulsion propellers situated respectively on each wing. Each propulsion propeller is inclined, and when it rotates it generates a thrust force (Fd, Fg) along a thrust axis (Pd, Pg) that is inclined relative to a longitudinal direction (X) of said hybrid helicopter. As a result, a longitudinal component and a transverse component of said thrust force (Fd, Fg) of each propulsion propeller act, during hovering flight of said hybrid helicopter, to generate respective torques that combine to form a moment (Mstat) opposing a yaw torque (CR) of said hybrid helicopter.
