介绍了民用飞机刹车系统的三个保护功能,即接地保护、锁轮保护和滑水保护功能,这三者虽然是刹车防滑功能的辅助功能,却对飞机的安全性和操作性有着重要影响。针对三个保护功能,分别分析了其设置目的、工作阶段、作用原理和控制逻辑,并给出了控制逻辑的建议值。鉴于其重要的安全性作用,进行了定性的安全性FHA需求分析。同时,对于控制逻辑相对复杂的锁轮保护功能,对比分析了两种不同控制方案,并给出了结论。
The three protection functions of the civil aircraft braking system are introduced, that is, the grounding protection, the lock wheel protection and the water slide protection function. Although these three are auxiliary functions of the brake skid function, they have an important influence on the safety and operability of the aircraft. According to the three protection functions, the purpose, working stage, action principle and control logic of the three protection functions are analyzed separately. The recommended values of the control logic are given. Given its important safety role, a qualitative safety FHA requirement analysis was conducted. At the same time, two different control schemes are compared and analyzed for the protection function of lock wheel with relatively complex control logic.
