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.
