HELICOPTER

PURPOSE:To accurately keep geometrical paths by providing other-direction thrust generating devices at different positions from a lateral thrust generating device provided a certain distance away from the center shaft of a main rotor, namely at the positions apart from the center shaft of the main rotor, and making it possible to control the thrust of both the devices separately. CONSTITUTION:A tail rotor 15 for negating reaction force in the opposite direction generated in the airframe 12 due to the rotation of a main rotor 11 is provided at a position a specific distance apart from the vertical shaft 20 of the main rotor 11, that is, at a tail 14. Further, other-direction) thrust generating devices 17, 18 for generating thrusts in different directions from the tail rotor 15 are provided at the different positions from the tail rotor 15, namely at the positions a specific distance apart from the vertical shaft 20 of the main rotor 11, on both sides of the airframe 12 in a state where they are supported by stays 16. The thrusts of the other-direction thrust generating devices 17, 18 and the tail rotor 15 are controlled separately to move the airframe backward and forward, sideways, and in oblique directions while the direction of the airframe 12 is kept constant.
