Abstract
An aerodynamic surface, such as a wing, empennage, angle of drift, nacelle pylon and the like for an aircraft includes at least one lightening hole pertaining to the trailing edge of the underwing, at least one hinged baffle that can be mounted in the lightening hole of the underwing, whereby the chord thereof is equal to a several hundredths of the chord of the aerodynamic surfacer and an actuator for the moveable baffle so that it can rotate around the hinge line.
Claims11
An aircraft aerodynamic surface comprising a reduced-pressure face and a pressure face which are connected together, at the front, by a leading edge and, at the rear, by a trailing edge, and at least one moving deflector articulated via its front part about an axis at least essentially parallel to said trailing edge so as to be able to pivot about said axis of articulation under the action of actuating means, wherein:
- a chord of said at least one deflector is equal to a few hundredths of a chord of said aerodynamic surface;
- said at least one moving deflector is housed in a recess made in the thickness of said pressure face, forward of said trailing edge and extending as far as the latter, and said at least one deflector can adopt:
- either a retracted extreme position, for which said at least one deflector is fully housed in said pressure face recess, ensuring the continuity of said pressure face or any one of a number of deployed positions, for which said at least one deflector is turned with its rear part projecting from said pressure face recess, thus giving the trailing edge of said aerodynamic surface a parametrizable variable thickness.
