The invention provides an electromechanical aircraft ejection seat program controller. The electromechanical aircraft ejection seat program controller comprises an electronic part 10 and a mechanicalpart 20. According to the electronic part 10, a differential pressure sensor 101 senses dynamic pressure qc from an aircraft airspeed head, and a microprocessor measurement and control assembly 102 collects and calculates an airspeed value V in real time. The microprocessor measurement and control assembly 102 starts timing and completes delay control after obtaining a seat ejection instruction: according to a preset seat ejection control law, the delay time TV adapts to the airspeed V, and after the delay time TV, a driving control signal is output to enable an electromagnet 103 to work and release first-stage brake 201; in the mechanical part 20, atmospheric static pressure Ps is sensed by an altitude capsule 202; the mechanical displacement of the altitude capsule 202 is associated withthe air pressure altitude in real time, when the atmospheric static pressure Ps is larger than a set value Ps0, the mechanical limiting mechanism of the altitude capsule 202 relieves limitation on the second-stage brake 203, and when double limitation of the second-stage brake 203 is completely released, a power spring mechanism 204 immediately outputs mechanical power. The controller system works stably and reliably and is convenient to implement.
本发明提供一种机电式飞机弹射座椅程序控制器,包括电子部分10和机械部分20。电子部分10由差压传感器101感受来自飞机空速管的动压q并由微处理器测控组件102实时采集和解算出空速值V,微处理器测控组件102在获得“座椅弹射指令”后开始计时并完成延时控制:根据预先设置的座椅弹射控制律,延迟时间T与空速V相适应,延时T后输出驱动控制信号使电磁铁103工作并释放一级制动201;机械部分20由高度膜盒202感受大气静压Ps,高度膜盒202的机械位移与气压高度实时关联,当大气静压Ps大于设定值Ps后,高度膜盒202的机械限位机构解除对二级制动203的限制,当二级制动203的双重限制全部释放后动力弹簧机构204立即输出机械动力。控制器系统工作稳定可靠,而且实施方便。
