Traction kite with negative dihedral

摘要

The wing has a flexible airfoil (12) defined between two lateral ends (14A, 14B) and presenting a propulsive median section between the ends. The section is bordered on both sides by control sections that are located at the level lower than that of the median section. The airfoil presents a leading edge (20) at the front and a trailing edge (22) at the rear, where the trailing edge is concave shaped.
