Abstract

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.
