摘要

The wing (2) has a partial curve contour (1) whose free ends (8, 9) are provided in terminal points (6, 7) of the partial curve contour. Radius vectors (Ra, Re) are aligned and directed with each other along opposite directions. The radius vectors form right angles (e, e'). A front side (11) of the partial curve contour is equipped with an elliptical arc (4) that is activated at a concave circular arc (5). Radius of curvature (Ka, Ke) is equal/unequal to sections of the circular arc. The partial curve contour and the vectors form the right angles in the terminal points of the circular arc.
