FIELD: aviation.
SUBSTANCE: the device is designed for a flight vehicle having a fuselage, jet engine, fuel system, carrying planes and control sections. The device has a source of offtaken gas, which through sealed lines is connected to the zones of local blowing-out of gas to the boundary layer of air flow on the surfaces the flight vehicle. Each zone of local blowing-out of gas is made on the surface of the carrying plane or fuselage, or control sections with a penetrable porous insert with a cross-sectional area of the ducts in the porous insert within 50 to 60% of the area of the insert proper by 10-15 times less than the distance between the adjacent inserts, a flat rectangular slot for a break of the boundary layer is made before each insert and in parallel with it.
EFFECT: reduced drag force and fuel consumption.
