摘　　要：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。This paper introduces three protection functions for brake system of commercial aircrafts. They are the touchdown protection, locked wheel protection and hydroplaning protection. Though the three functions are parts of antiskid protection, they significantly affect the safety and operability of the aircraft. This paper analyzes the purposes of its establishment, the working phases, the principle and control logic for the three functions , and gives the proposed value of the control logic. Furthermore, the Functional Hazard Assessment （FHA） requirements are analyzed because of the important safety effect. Meanwhile two control schemes are compared and analyzed for the complexity of locked wheel protection , and the conclusion was given.
