Cross-sectional shape of an aero- and hydrofoil which sets a fluid into motion or which is set into motion by a fluid

摘要

The invention relates to a wing form or vane form by means of which thrust and lift can be aerohydrodynamically optimally exchanged between the fluid and the form. To this end, the form, with its partially concave top side, optimizes the pressure differences between underside and top side of the blade (vane). The thin trailing edge (tail) oriented in the direction of movement contributes to the reduction of the ((induced) form) drag.
