The invention provides an aircraft landing gear emergency release system which is designed for redundancy insurance arranged in a large aircraft. Comprising a front unlocking mechanism used for unlocking a nose landing gear lock, two rear unlocking mechanisms used for unlocking a rear landing gear lock, a handle mechanism for an aircraft driver to manually operate and unlock, a main linkage mechanism and an auxiliary linkage mechanism, and the main linkage mechanism and the auxiliary linkage mechanism are used for driving the three unlocking mechanisms to synchronously unlock. An aircraft pilot can manually operate through the handle mechanism, the main linkage mechanism and the auxiliary linkage mechanism which are connected with the handle mechanism drive the three unlocking mechanisms to act at the same time, locks of the front undercarriage and the rear undercarriage are unlocked at the same time, then the three undercarriages can be put down under the action of gravity, and therefore emergency putting down of the undercarriages is achieved. And when the original control system fails, the landing safety of the large aircraft is ensured.

    本发明提供一种飞机起落架应急放系统,为设置在大型飞机中的冗余保险设计,包括用于将前起落架锁具解锁的前方开锁机构、用于将后起落架锁具解锁的两个后方开锁机构、供飞机驾驶员手动操作解锁的手柄机构、以及用于带动三个开锁机构同步进行开锁的主连动机构、副连动机构,因此在原控制系统失效时,飞机驾驶员可通过手柄机构手动操作,通过与之连接的主、副连动机构同时带动三个开锁机构动作,同时将前、后起落架的锁具打开,随后三个起落架就可在重力作用下放下,从而实现起落架的应急放下,在原控制系统失效时保障大型飞机的降落安全。
