某大型水陆两栖飞机因为主起落架采用下位插销锁,放下时需要全过程有源作动,同时飞机下部为水密船身,安装空间紧张,传统的机械钢索应急放系统难以实现,所以设计了一套高压气动应急放系统,用于在正常放与备用放系统都失效的情况下放下起落架。 Because of the main landing gear with a lower latch lock, a large amphibious aircraft needs to be activated during the entire process when it is lowered. At the same time, the lower part of the aircraft is watertight. Due to the tight installation space, the traditional mechanical cable emergency release system is difficult to realize. Therefore, A high-pressure pneumatic emergency release system to lower the landing gear in the event of failure of both normal and standby systems.
