The embodiment of the invention discloses a high-speed protection control method for a large amphibious aircraft, and the method comprises the steps: generating a high-speed protection pitch angle stabilization instruction according to the current pitch angle of the aircraft after the aircraft enters a high-speed protection state, the high-speed protection pitch angle stabilizing instruction and a high-speed protection pitch angle instruction generated based on the driving intention of a pilot are superposed to generate a high-speed protection pitch angle control instruction, and after the high-speed protection pitch angle control instruction is converted into a high-speed protection overload instruction, the high-speed protection overload instruction and an aircraft main flight control law instruction are superposed; therefore, a safe, efficient and stable high-speed protection control effect is realized. According to the technical scheme provided by the embodiment of the invention, the problems that the pitch angle of the aircraft is too large in the high-speed protection execution process by adopting the existing high-speed protection control mode, and the aircraft still flies at a relatively large pitch angle after exiting high-speed protection are solved; and the method is not suitable for large amphibious vehicles and possibly endangers the flight safety.

    本发明实施例公开了一种大型水陆两栖飞机的高速保护控制方法,包括:在飞机进入高速保护状态后,根据飞机当前俯仰角生成高速保护俯仰角稳定指令,所述高速保护俯仰角稳定指令与基于飞行员驾驶意图生成的高速保护俯仰角指令叠加后生成高速保护俯仰角控制指令,将高速保护俯仰角控制指令转化为高速保护过载指令后,与飞机主飞行控制律指令进行叠加处理,从而实现安全、高效、平稳的高速保护控制作用。本发明实施例提供的技术方案解决了采用现有高速保护控制方式在执行高速保护工作过程中可能会出现飞机俯仰角过大情况,并且在退出高速保护后飞机仍以较大俯仰角飞行,对于大型水陆两栖并不适用以及有可能危及飞行安全的问题。
