Abstract

The embodiment of the invention discloses a wing structure. The wing structure comprises a wing body, an upper skin, a lower skin and a leading edge patch, wherein the upper skin is attached to the upper surface of the wing body, and the lower skin is attached to the lower surface of the wing body; and a groove is formed in the leading edge patch, the leading edge patch is arranged on the wing body in a sleeving mode through the groove, and a joint of the upper skin and the lower skin is located in the groove. The wing structure can reduce the probability of delaminating or cracking at the joint of the upper skin and the lower skin of the wing.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a wing structure. Background technique [0002] In recent years, unmanned military equipment has penetrated into almost every field of the battlefield space. UAVs have become an important and even key force affecting the combat process and have been valued by more and more countries. The military departments of many countries have put UAVs as Development is given priority. [0003] At present, the composite material wing structure basically adopts the structure of upper and lower skin + skeleton. There are problems of delamination and cracking at the junction of the upper and lower skins of the leading edge of the wing during use. [0004] Therefore, it is necessary to develop a wing structure that can reduce the probability of delamination or cracking at the junction of the upper and lower skins of the wing. [0005] The information disclosed in the background of the present invention...
