Due to special function requirements of a certain type of airplane, a flap cabin adopts a sealing plate structure. During the outfield flight, the flap cabin sealing plate has cracks.
When the aircraft takes off or lands, the flap deflects downwards, the baffle deflects upwards, the flap cabin sealing plate, the baffle and the flap leading edge form a narrow slit channel together, and airflow flows from the lower wing surface to the upper wing surface through the slit channel. In the process, as the airflow is blocked under the flap, part of the high-speed airflow enters the inside of the flap cabin through the slot, and strong broadband pressure pulsation is formed. The pressure pulsation acts on a clapboard and a covering of the flap cabin. When a certain order of main vibration modes of the partition plate, the web plate and the skin fall within the frequency band range of air pressure pulsation, continuous excessive vibration is generated under continuous excitation of the pressure pulsation, and finally high-cycle fatigue damage of the sealing plate of the flap cabin is caused.
