The invention belongs to the field of engine throttle control, and relates to an aero-engine throttle fault state control method, which comprises the following steps that: a state increasing switch and a state reducing switch are arranged in a cabin, a state increasing identifier and a state reducing identifier are arranged in a controller, and the controller acquires throttle lever data of the state increasing switch and the state reducing switch in real time; when the state increasing switch or the state decreasing switch is switched on, the timer starts timing, and whether the state increasing switch is pressed for a long time or a short time is judged according to timing time; control is carried out according to long pressing and short pressing and different accelerator speeds; and when the state increasing switch or the state decreasing switch is withdrawn, keeping the final state of the switch corresponding to the disconnection moment for continuous oil supply. And under the condition of'minimum cost '(only two switches and two cables are added), the state of the engine is controlled when the control accelerator breaks down, and the accidents of machine destruction and human death caused by small-probability events of the control accelerator fault are avoided.
本申请属于发动机油门控制领域,为一种航空发动机油门故障的状态控制方法,在座舱内设置状态增加开关和状态降低开关,在控制器内设置状态增加标识和状态降低标识,控制器实时采集状态增加开关和状态降低开关的油门杆数据;当状态增加开关或状态降低开关接通时,计时器开始计时,根据计时时间判断状态增加开关为长按还是短按;并根据长按和短按按照不同的油门速率进行控制;当状态增加开关或状态降低开关退出时,保持断开时刻对应开关的最终状态持续供油。在“最小代价”的情况下(仅增加2个开关和2根线缆即可),实现了控制油门故障时发动机状态的控制,避免了由于控制油门故障小概率事件导致的机毁人亡事故。
