FIELD: aviation. SUBSTANCE: aircraft has aerodynamic surface mounted on casing 1 which is round in plan. Upper part of this surface has form of horizontal lifting plane 2. Aircraft is provided with jet engine whose nozzle guide vanes have circular slot 3 with shoulder 10 above center portion of plane 2 so that annular gas jet gets in contact with its peripheral portion only. Mounted below and around plane 2 is partition 4 having cylindrical surface for separation of gas-and-air flow formed by gas jet from space above plane 2 due to avoidance of ejection of air from under plane 2. EFFECT: increased lift force. 5 cl, 2 dwg
