Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The lifting surface of an aircraft, according to claim 1 , wherein the lifting surface is a horizontal stabilizer. 3. The lifting surface of an aircraft, according to claim 1 , wherein the cross-section of the retractable cover element follows the shape of the cross-section of the leading edge. 4. The lifting surface of an aircraft, according to claim 1 , wherein the third wall of the notch comprises a streamlined shape. 5. The lifting surface of an aircraft, according to claim 1 , wherein said notch does not extend beyond a front spar of the horizontal stabilizer. 6. The lifting surface of an aircraft, according to claim 1 , further comprising an actuation mechanism for retracting said retractable cover element. 7. The lifting surface of an aircraft, according to claim 1 , wherein the aspect ratio chord/span of the notch is greater than 1. 8. An aircraft comprising the lifting surface according to claim 1 .
