FIELD: transport.
SUBSTANCE: invention relates to device intended for generation of propellant forces for vehicles. Proposed method is characterised by drag effects on wing front surface or screw front surface wherein ram inflow on plane periphery is turned and tangential flow is created on rear plane with speed smaller than that of ram flow. Flow on rear surface front edge is directed from the root to plane lateral edge and intersect it with flow swirled long lateral edge of the plane read surface for their interaction to create force oriented along the plane. Ram flow is used to stabilise boundary layer on the plane rear surface rear edge. In compliance with the first version, aircraft cuts in propellers. Peripheral plane of propeller blade accommodates the structure of profiles with its elements. Another version of aircraft comprises wings. Structure of profiles is located on wing plane periphery.
EFFECT: higher efficiency of converting drive power into propellant power.
