Embodiment
[0014] This circuit can be used when the command ejection system is in two-state start control. When the switch K1 is turned into a closed state, that is, the ejection of the front seat is started, and the electric detonator of the front seat is fired immediately to complete the restraint function of the front seat occupant. The ejection start signal is transmitted to the rear seat, and the rear seat initiates the ejection and executes the ejection control program.
[0015] If the ejection of the rear seat is started, that is, when the switch K2 is turned into a closed state, the ejection of the rear seat is started and the ejection control program is executed. Ejection control program for front seat.

The invention belongs to the field of airplane life saving, and relates to a starting signal mutual transmission circuit of a double-seat machine instruction ejection system. The circuit comprises a hardware circuit installed on a seat A and a seat B, and a transmission cable connected with the two seats A and B; the hardware circuit installed on the seat A and the seat B comprises a capacitor andan optical coupler, the input end of the optical coupler is connected with seat capacitors in series, and the output end of the optical coupler is connected with an ejection starting switch of the other seat in parallel through the transmission cable. According to the circuit, the problem that previous fuel gas transmission of ejection starting signals needs to consider the influence of internalpressure of seats and cockpit pipelines is solved, the weight of machine mounting is reduced, and the use maintainability is improved.
Description
technical field [0001] The invention belongs to the field of aircraft lifesaving, and relates to a starting signal mutual transmission circuit of a command ejection system of a two-seater aircraft. Background technique [0002] The electronic command ejection system mainly realizes the automatic control of the sequence and time interval of emergency ejection of the occupants of the two-seater fighter. In the dual state, as long as there is an ejection start signal between the front and rear seats or the side-by-side seats, the other seat will receive the ejection start signal and perform corresponding control. The active rocket ejection seat command ejection system uses gas as power when it works, and the gas transmission is realized by adding explosive bombs, and the ejection start signal is transmitted to another seat. Adopting this method requires arranging corresponding pipelines and installing detonation bombs and delay bombs in the aircraft cockpit, which not only red...
