Aircraft wing with high swept back leading edge, particulary delta wing

摘要

The aircraft wing (3) has sharply swept-back leading edges (7). A conical vortex forms on the suction side (5) when air flows over the wing. There is at least one guide surface (11) for this vortex, forming an angle ( delta ) to the normal to the aircraft's longitudinal axis (2) of not more than 85 degrees . The guide surface runs parallel to the axis (12) of the conical vortex and between it and the leading edge.
