Research on Static Stability of Lunar Lander with Legs

Abstract

Abstract: Stability margin is used to describe the static stability.The mathematical relationships between the static stability characteristics and the geometry and ubiety parameters of lunar lander with legs were derived.The effects of parametric quantitative change on static stability characteristics were analyzed.The static stability characteristics of lunar lander with three legs and four legs were compared.The results show that the lunar lander with four legs is more steady than the lander with three legs.The lunar lander with legs was designed and optimized based on these mathematical relationships and results.

Key words: Snubber, Structural design, Static stability, Stability margin, Lunar landing module
