FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to rotorcraft lift development. This vehicle is composed of two disc-like surfaces arranged one above the other with clearance there between. Gas flow generator is built in at the centre of top disc, gas flow being forced in tunnels composed between top and bottom surfaces and separated by ribs arranged in radii from disc centre to periphery. Top surfaces of tunnels are provided with threads that make the brush-like surface directed downward.
EFFECT: enhanced applications.
