The sealing plate structure mainly includes the upper sealing plate and the lower sealing plate two parts, in the process of aircraft operation mainly play a sealing aircraft structure, to ensure that the aircraft surface flatness, resistance to aerodynamic forces on the aircraft operation process interference, and stabilize the normal flight of the aircraft. In order to ensure the high-speed operation of the aircraft, the overall quality of the sealing plate is required to ensure the safety performance under the premise of as low as possible, and at the same time to meet the requirements of its high strength, high stiffness. And also to have a large deformation, high resilience, good abrasion resistance and other characteristics to cooperate with the operation of the part of the many moving institutions.

The sealing structure developed by the company has the characteristics of high strength and high rigidity to withstand strong aerodynamic suction to maintain the aerodynamic seal between the main wing and aileron. At the same time, it has the characteristics of large deformation, high resilience and good abrasion resistance to match the operation of the many moving mechanisms in the part. And the sealing structure material should also have anti-fatigue, high and low temperature resistance, long life and other requirements.
