FIELD: aircraft industry.
SUBSTANCE: invention relates to special design body of forced flow-air jet engine which has section made square to install rotary shutters on hinge joints with long rods. Section of reaction nozzle is also made square, and rotary plates are installed in nozzle at different levels in horizontal plane to cut off thrust at takeoff and landing of aircraft through air duct for forming air cushion under lower plane of flat fuselage and, in process of landing, to direct vector of thrust opposite to direction of flight for deceleration.
EFFECT: improved operating characteristics of aircraft owing to effective control at takeoff, landing and cruising.
