FIELD: aeronautical engineering; manufacture of helicopters with extended functional parameters. SUBSTANCE: helicopter, mainly co-axial helicopter, includes framework on which wing and main rotor system with main rotors mounted on it are installed. main rotors are provided with wobble plate. To increase speed and/or flying range of helicopter, its main rotor system is mounted on framework for inclination through maximum angles of attack of main rotors relative to direction of flight. Main rotor system may be mounted on helicopter by means of articulated point which makes it possible to incline main rotors through angle of attack of 90 deg. Controllability and stability of helicopter may be checked by means of wobble plate. EFFECT: increased speed and/or flying range of helicopter. 2 cl, 4 dwg
