An electromechanical aircraft ejection seat program controller and control method

Abstract

The present invention provides an electromechanical aircraft ejection seat program controller, which includes an electronic part 10 and a mechanical part 20 . The electronic part 10 senses the dynamic pressure q from the pitot tube of the aircraft by the differential pressure sensor 101 c The airspeed value V is collected and calculated in real time by the microprocessor measurement and control component 102, and the microprocessor measurement and control component 102 starts timing and completes the delay control after obtaining the “seat ejection command”: according to the preset seat ejection control law, delay time T V Adapt to airspeed V, delay T V Then output the drive control signal to make the electromagnet 103 work and release the primary brake 201; the mechanical part 20 feels the atmospheric static pressure Ps from the altitude capsule 202, and the mechanical displacement of the altitude capsule 202 is related to the air pressure height in real time. When the atmospheric static pressure Ps Greater than the set value Ps 0 Finally, the mechanical limit mechanism of the height bellows 202 releases the restriction on the secondary brake 203, and the power spring mechanism 204 outputs mechanical power immediately after the double restrictions of the secondary brake 203 are all released. The controller system works stably and reliably, and is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of ejection control of aviation lifesaving systems, and relates to an electromechanical aircraft ejection seat program controller and a control method. Background technique [0002] At present, there are mechanical and electronic controllers for aircraft ejection seats, and the electromechanical controllers are few and simple. The mechanical ejection seat program controller has air pressure altitude and airspeed control, but the existing mechanical airspeed control part has low precision and cannot be adjusted after the control law is fixed, which cannot meet the system requirements. And because the mechanically controlled ejection seat program controller has the advantages of stable and reliable operation, the aircraft system also needs an adjustable control law, and the demand for an electromechanical ejection seat program controller is proposed. Therefore, it is necessary to provide an electromechanical ...
