Abstract

Abstract: To control the stability of ejection-seat-pilot system, the distribution of combined gravity center of the system is studied. The distribution equations are derived and an elliptic distribution model is established. The results of being applied in the stabilization adjustment design of ejection-seat-pilot system show that the distribution model is accurate and effective, which supplies an effective criterion to stabilization adjustment during ejection seat development.

Key words: ejection seat, pilot, CG(center of gravity), distribution, stability
