The invention belongs to the field of aircraft structure design, and particularly relates to a plug-in type strake wing leading edge. Comprising an edge strip wing leading edge, an inner side wall plate, an outer side wall plate and a framework, the inner side wall plate is attached to the outer surface of the framework, the edge strip wing leading edge is integrally formed and comprises an upper wing surface, a lower wing surface, a flash, a cavity and an edge strip, the area, matched with the flash, of the inner side wall plate is provided with a sunken part, the upper wing surface is fused with the edge of the flash, the flash is locally widened, and the edge strip is arranged in the sunken part. A groove is formed in a matching area of the inner side wall plate and the upper wing surface, the groove is used for being matched with a widened area on the flash edge, the edge strip wing front edge is arranged between the inner side wall plate and the outer side wall plate, and the outer side wall plate and the framework are fixed in a riveting mode. The structural form is good in structural rigidity and convenient to connect with the side wall plate of the fuselage. And after being influenced by aerodynamic load, the edging wing is not easy to deform, and the aerodynamic shape of the front edge of the edging wing can be well ensured.
本发明属于飞机结构设计领域,具体涉及一种插接式边条翼前缘。包括边条翼前缘、内侧壁板、外侧壁板和骨架,所述内侧壁板贴合在所述骨架外表面上,所述边条翼前缘一体成型,包括上翼面、下翼面、飞边、空腔和缘条,所述内侧壁板上与飞边配合的区域设有下陷,所述上翼面与飞边边缘融合,飞边上局部加宽,所述内侧壁板与所述上翼面配合区域设有凹槽,所述凹槽用于与所述飞边上加宽区域配合,所述边条翼前缘设置在所述内侧壁板与外侧壁板之间,所述外侧壁板与所述骨架采用铆接固定。此种结构形式结构刚性较好且便于与机身侧壁板连接。受气动载荷影响后,不易变形,可以较好的保证边条翼前缘气动外形。
