摘要: 为解决火箭弹射座椅在弹射出舱后的稳定性调节问题,对弹射座椅与飞行员系统组合重心的分布规律进行了理论研究,求解出了组合重心的分布方程,建立了组合重心的椭圆分布模型。研究结果已应用于弹射座椅与飞行员组合系统稳定性调节的工程设计中,应用实践表明所建模型准确、有效。

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.
