Abstract
A lifting surface of an aircraft, comprising a leading edge and a notch located in the leading edge. The notch comprises two walls adapted to be parallel to the direction of the incident flow to the lifting surface and a third wall adapted to face the incident flow to the lifting surface when it is in flight. The lifting surface also comprises a retractable cover element, the notch and the retractable cover element being configured such that when the retractable cover element does not cover the notch, the notch is exposed to the incident flow generating a vortex which increases the lift force of the lifting surface, delaying stall.

A lifting surface of an aircraft, comprising:
- a leading edge and
- a notch located in said leading edge,
- the notch comprising two walls adapted to be parallel to the direction of the incident flow to the lifting surface and a third wall adapted to face the incident flow to the lifting surface when it is in flight,
- the lifting surface also comprising a retractable cover element,
- the notch and the retractable cover element being configured such that when the retractable cover element does not cover the notch, said notch is exposed to the incident flow generating a vortex which increases the lift force of the lifting surface, delaying stall, wherein the retractable cover element is retracted toward the tip of the lifting surface and is placed above the leading edge of the lifting surface when retracted.
