noise reduction systems for retractable auxiliary wing wings of the wing leading edge of an aircraft wing assembly

摘要

it is a noise reduction system, which provides noise reduction for a wing assembly supplied with a front edge auxiliary airfoil, and includes an elongated protection element, which is disconnected, but positionable, adjacent to a trailing edge lower edge of the auxiliary airfoil along its length, and a support strip, which has a distal end attached to the protective element, and a proximal end capable of being attached to a hidden surface inside the airfoil auxiliary edge adjacent to an upper trailing edge thereof. the support strip will therefore allow movement of the protective element towards and away from the lower trailing edge of the edge auxiliary airfoil, between an operating position, where the protective element is positioned adjacent to the trailing edge bottom of the edge auxiliary wing along its length and in an inoperative position, in which the edge auxiliary wing is away from the trailing edge of the edge auxiliary wing and positioned in its hidden region, respectively.
