Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, so as to more clearly connect the inventive principle and beneficial technical effects of the present invention.

[0047] Explanation of terms used in this article:

[0048] The extension direction of the anti-bird strike leading edge of the aircraft along the wingspan is called the longitudinal direction;

[0049] The direction perpendicular to the direction of extension of the leading edge is called transverse;

[0050] The direction between the upper side and the lower side of the leading edge is called the thickness direction;

[0051] In the transverse direction, the part adjacent to the front side of the leading edge is called "front";

[0052] In the transverse direction, the rear side adjacent to the leading edge is called "rear".

[0053] Such as figure 1 and 2 As shown, it shows a preferred embodiment according to the present invention. fi...

Abstract

The invention provides a supporting body for a bird strike-resistant aircraft leading edge. The supporting body comprises an auxiliary beam, a front beam and a leading edge cabin rib, wherein the auxiliary beam is positioned at the front part of the leading edge and stretches longitudinally; the auxiliary beam is corrugated and comprises a front surface side and a back connecting side opposite tothe front surface side; the front beam is positioned on the back part of the leading edge and stretches longitudinally; the leading edge cabin rib is positioned between the auxiliary beam and the front beam; the leading edge cabin rib comprises a front connecting end and a back supporting end opposite to the front connecting end; the auxiliary beam is attached to the back side of leading edge skinof the leading edge so as to form a cavity between the auxiliary beam and the leading edge skin; the back connecting side of the auxiliary beam is connected to the front connecting end of the leadingedge cabin rib through a connecting component; the back supporting end of the leading edge cabin rib is fastened to the front beam through a fastening component. The invention further provides the bird strike-resistant aircraft leading edge using the supporting body. According to the invention, the bird strike resistance of the leading edge of a wing is significantly improved.

Description

technical field [0001] The invention relates to an aircraft leading edge and a support body for the aircraft leading edge, in particular to an aircraft anti-bird strike front edge and a support body structure for an aircraft anti-bird strike front edge. Background technique [0002] The anti-bird strike performance of aircraft leading edge is a key factor to measure the success of an aircraft leading edge design. [0003] The leading edge structure used in early aircraft was mainly made of metal aluminum alloy. In order to improve the anti-bird strike performance, a large price was often paid for weight, such as B737, MD82, MD90 and other aircraft. Therefore, as composite materials are more and more used in civil aircraft, major aircraft manufacturing companies are considering the application of new materials to reduce structural weight while improving bird strike resistance. [0004] For example, the leading edge of the A320 empennage adopts a sandwich structure of honeyco...
