Numerical simulation calculation of ejection seat´s stability at the phase of ejecting from cabin

Stability is one of the performance indexes of ejection seat. The certain type of ejection seat is regarded as the subject studied. Based on analyzing the motion law of ejection seat ejecting from cabin, a computational model of stability has been established. By theoretic calculating and test verification, this model can describe the stability of the phase that the ejection seat ejection ejecting from cabin accurately, and provide a reference for stability research of ejection seat at the other complicated situations.
