Fore flap disposed on the wing of an aircraft

摘要

A leading edge slat arranged on the aerofoil of an aircraft. The leading edge slat is provided on the front of the main wing. The leading edge slat has a partially extended setting, with its trailing edge flat against the wing, and a further extended setting, with its trailing edge spaced apart from the nose of the wing to open a gap feeding high-energy air from the lower surface of the slat to the upper surface of the wing. The leading edge slat includes a body and a trailing edge facing the main wing, which can be bent around the spanwise direction of the slat relative to the body, and on which the trailing edge of the slat is provided, and which by means of a device generating a contact force is loaded for making contact between the trailing edge of the slat and the profile nose of the wing.

1. A leading edge slat arranged on an aerofoil of an aircraft, wherein
the aerofoil comprises a main wing with an upper surface skin, a lower surface skin, and a profile nose, and the leading edge slat is provided on the front of the main wing and has a profile nose directed forwards and a trailing edge directed rearwards, facing the main wing, and from a retracted cruise setting, in which the leading edge slat lies flat against the front of the main wing and supplements the profile of the latter to form a shape suitable for cruise flight, can be extended for purposes of increasing the lift with an increase in curvature and extension of a wing profile in the wing chordwise direction, wherein the leading edge slat in a first, partially extended, setting with the trailing edge lying flat against the main wing and in a second, further extended, setting with the trailing edge spaced apart from the profile nose of the main wing so as to open up a gap feeding high-energy air from the lower surface of the leading edge slat to the upper surface of the main wing, wherein the leading edge slat comprises a main body and the trailing edge part facing the main wing, which can be bent flexibly around the spanwise direction of the leading edge slat relative to the main body, and on which the trailing edge of the leading edge slat is provided, and which, by means of a device generating a contact force, is loaded for purposes of making contact between the leading edge slat trailing edge and the profile nose of the main wing, wherein the trailing edge part is connected with the main body of the leading edge slat via an articulation, in order that the edge that trailing edge part can be bent flexibly around the spanwise direction of the leading slat relative to the main body, wherein the articulation is formed by an elastic-in-bending element, wherein the elastic-in-bending element is formed by the trailing edge part itself, which, at least in a region adjacent to the main body of the leading edge slat, is formed by an elastic, flexible material, and wherein all of the articulation of the trailing edge with respect to a leading edge of the leading edge slat occurs within the elastic-in-bending element.
