Flow dynamic surface, particularly carrier, guiding and control surfaces of aircraft, water craft, drive propeller, fan, helicopter and wind-power plant, has free point arranged at surface

摘要

The flow dynamic surface (2) has free points arranged at the surface. A turbine (6) drives a propeller (9) by a gear (8), with a firm conversion, into the peripheral vortex (4) against set rotating direction (10). The propeller is arranged against incident flow before the flow dynamic surface.
