Abstract: The effects of deceleration parachute of ejection seat on ejection trajectory were analyzed under low velocity condition. Through trial method and simulation, delay time of parachute opening was optimized in terms of maximum mobile load and maximum velocity. The results showed that the curve-optimized of delay time was positive correlated with maximum velocity of rescue parachute. Collectively, the curve -optimized of delay time may be used in the area of engineering instruction.
