Provided is a flight efficiency improving system for a compound helicopter (1) comprising a rotor (3) and fixed wings (4). In forward flight of the compound helicopter (1), the flight efficiency improving system does not perform a cyclic pitch control of the rotor (3) so as to allow a difference in lift generated by the rotor (3) between an advancing side and a retreating side of the rotor (3), or the flight efficiency improving system performs the cyclic pitch control to an extent that does not completely eliminate the difference. The fixed wings (4) are provided respectively on left and right sides of a body (2) and are asymmetric to each other so that influence of an aerodynamic interference between the rotor (3) and the fixed wings (4) is reduced.
