气球落舱内试验平台的高微重力水平分析
ANALYSIS OF HIGH QUALITY MICROGRAVITY ABOUT BALLOON-RELEASED TEST PLATFORM
【摘要】 研究了一种新型高微重力水平气球落舱内试验平台的动力特性,考虑了稀薄气体的影响,建立了落舱及平台的动力学方程.通过数值计算获得了平台微重力水平与落舱控制精度、平台与落舱的分离时刻、真空舱内真空度的关系.
【Abstract】 Some dynamic characters of a new balloon-released test platform in capsule with high quality microgravity are studied in this paper. The dynamics equations are obtained by considering the effect of the rarefied gas and the free molecular flow in vacuum chamber. The relationship between microgravity and control precision, detach time of platform from capsule, and pressure of the vacuum chamber are obtained by simulation.
