Abstract

The invention provides an aileron cabin sealing structure, which is used for connecting and fixing the rear edge skin (21) and the aileron skin (22), and the shell one (3) and the shell two (4) are fixedly connected to the fixed trailing edge At the two ends of the same side of the skin (21), a rotating bearing one (5) and a torsion spring one (7) are installed inside the housing one (3), and two rotating bearings (6) and Torsion spring two (8), rotating shaft (1) one end passes through rotating bearing one (5) and torsion spring one (7) successively, and the other end passes through rotating bearing two (6) and torsion spring two (8) successively, is arranged on Between shell one (3) and shell two (4), one side of the steel film is fixedly connected to the rotating shaft (1), and the other side is connected to the pressure piece (9) and the aileron skin (22) by fasteners. )between. The aileron compartment sealing structure provided by the present invention optimizes the sealing form of the aileron compartment, avoids twisting and tearing of rubber sealing profiles, improves aerodynamic sealing efficiency, and reduces maintenance costs.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and in particular relates to an aileron cabin sealing structure. Background technique [0002] In order to ensure the flight quality, a rubber strip is installed on the fixed trailing edge of the wing, which is pressed against the leading edge of the aileron to prevent airflow from entering the aileron compartment. There is a certain amount of interference between the rubber strip and the leading edge of the aileron. After the aileron is deflected many times, the rubber strip is prone to twisting and tearing, which affects the sealing effect. In the actual design, in order to avoid interference with the aileron suspension arm and actuator when the aileron rotates, several openings are designed on the leading edge of the aileron. When the aileron deflects back again, the edge of the aileron opening and the rubber strip interfere to generate a force along the course, causing the rubber str...
