[0002] The new generation of ejection life-saving systems generally adds a speed control life-saving function, which is realized by a speed control parachute-opening device. It can determine the safe unlocking time according to the flight speed, and can significantly improve the life-saving reliability. The delay mechanism of the speed control parachute-opening device needs to preset the timing power from the spring power mechanism in advance, and it needs to be carried out in advance before the speed control parachute-opening device is installed on the seat.
