FIELD: motion in air medium at subsonic speed; subsonic flying vehicles, high-speed ships, trains and trucks.
SUBSTANCE: proposed method consists in change of state of boundary layer of transport facility by smoothly heating of at least 70% of surface of transport facility at permissible temperature gradient of ±20°C to temperature not below 60°C connecting the engine plant of transport facility, air intake or compressor by means of mains with passages adjoining from the inside to external skin of transport facility. According to one version of method, heated mixture of air and combustion products is additionally locally blown out through permeable porous inserts on surfaces of transport facility into air flow around it at definite velocity of this flow. Device proposed for realization of this method includes body of transport facility, engine plant 1 and system for change of state of boundary layer formed by air intake or compressor connected with engine plant of transport facility by hermetic mains 5 provided with passages adjoining from the inside to external skin 9 of transport facility body. According to other versions, mains are also brought to porous inserts 11 of skin 9.
EFFECT: enhanced efficiency.
