摘要

摘要:
主翼面与可动翼面之间的缝隙会对飞机飞行性能造成一定影响，缝隙封严结构的应用会改善机翼的表面光滑性，同时达到增升减阻、优化操纵等效果。基于此，对5种封严结构设计形式进行对比，并将封严结构的设计分为依靠机构和依靠材料2类，分析了其优缺点。比较了4家航空配件公司的封严结构产品，分析了耐磨自由端细节设计。给出了快速拆装修理、限制结构刚度范围、设计时仿真与试验相结合等设计建议。

Abstract:
The gap between the main wing surface and the movable wing surface might have a certain impact on the flight performance of the aircraft. The application of the gap-sealing structure will improve the surface smoothness of the wing while achieving effects such as increasing lift, reducing drag, and optimizing operation. This article compares various sealing structure design forms and divides them into two categories: relying on materials and relying on mechanisms. The benefits and drawbacks of each category are examined.The sealing structure products of several aviation parts companies are compared. Analysis is done on intricate designs like wear-resistant free ends. Design suggestions are provided at last, such as rapid disassembly and repair, limitation for the range of the structural stiffness, and a combination of simulation and experiment while designing.
