Description

Electronic instruction ejection system for ejection mode switching control

Technical Field

The invention relates to an electronic instruction ejection system for ejection mode switching control.

Background

In three aircraft, the electronic command ejection system is required to have three command ejection control modes, namely a single ejection mode, a double ejection mode and a three ejection mode. Under different ejection modes, the timing of the taking-out of each seat is different. If the seat No. 3 is out of the cabin, the seat No. 1 and the seat No. 2 need to complete the conversion from the three-bullet mode to the double-bullet mode, so that the emergency ejection out-of-cabin time of a pilot is shortened, and the life-saving performance is improved. At present, the mode switching of the domestic electronic instruction ejection system is controlled by a switch, ground service personnel are required to lock the mode selection switch on the ground, and after the aircraft is on the day, the seats No. 1 and No. 2 can only carry out instruction ejection according to a fixed double-ejection mode or a three-ejection mode. The ejection mode switching method has the advantages of high labor cost, clumsy control method, possibility of causing ejection mode switching errors and reduction of life saving performance.
