FIELD: transport.SUBSTANCE: invention relates to aviation, in particular, to vertical take-off and landing aircraft designs and methods. Flight method includes creation of air flow directed downwards by means of coaxial propulsors with counterrotating blades. The blades are capable to rotate around their longitudinal axis with angle of incidence change. By changing angle of rotation of propulsor blades within period of each revolution, thrust vector horizontal component and flight stabilisation are provided. Horizontal thrust in steady horizontal flight mode is created by jet propulsor. By turning propulsor blades up to angle of incidence of 0° in the mode of prolonged horizontal flight, closed aerofoil is created - rotating wing with possibility of lifting force creation. The propulsors are connected with engine via drive - reducing gear system. Propulsor blades are connected with tilt system, gyroscope and control system.EFFECT: higher manoeuvrability, speed, efficiency of aircraft in the mode of horizontal flight.2 cl, 3 dwg |
