FIELD: aeronautical engineering.
SUBSTANCE: proposed method consists in taking preheated gas from gas source and bringing it to flying vehicle surface followed by blowing-out jet of preheated mixture of air and combustion products of engine plant at subsonic velocity through local blowing-out zones on lower and/or upper surfaces of flying vehicle wing into external incoming air flow. Besides that, air is taken from air intake or from engine plant compressor and is fed over hermetic mains through adjusting members at supersonic velocity through supersonic nozzles which are flat in configuration from leading edge of wing over lower surface in way of wing chord, thus overlapping the subsonic gas jets escaping from local blowing-out zones by high-velocity air flow at Mach number more than 0.7. Device proposed for realization of this method has fuselage, power plant, engine plant, fuel system, wing and control profiles. Engine plant is connected by hermetic lines with local blowing-out zones located on surfaces of wing and control profiles. Mounted on leading edge of wing lower surface are supersonic nozzles whose external surfaces are located at level of wing surface.
EFFECT: increased lifting force.
