摘　　要：高速保护功能作为主动控制技术之一,已在当代电传民机上广泛应用。结合空客电传民机设计实例,首先分析了该功能的必要性和设计目标;其次探讨了该功能的设计考虑,包括高速保护裕度考虑、高速保护方案考虑和故障情况下的考虑;最后阐述了高速保护与其它包线保护功能的关系,包括与滚转角保护的关系、与俯仰角保护的关系和与法向过载保护的关系。As one of the active control technology function, high speed protection has been widely implemented in various modern commercial airplanes. Starting from Airbus real design example, the necessities and design targets of high speed protection function are analysed. And some detail design considerations are elaborated which inclu-ding speed margins between VC and VD, control law design schemes and failure conditions. Finally, the relation-ship between high speed protection and the other envelop protection function including bank angle protection , pitch attitude protection and normal load factor are discussed.
