A review of nutation instability mechanism on spinning solid rocket motor flight vehicle
摘要
Abstract
The instability mechanism of nutation phenomenon which appears in the last stage of launching small satellite using spinning solid rocket motor was analysed. The nutational instability characteristics of flight vehicle were analysed according to practical observational flight data. Several kinds of possible instability mechanisms which result in lateral angle motion were given, and then they were analysed according to actual situation. The result shows that the main reason of the instability motion of flight vehicle is the interaction of the mass variation of flight vehicle and unsteady flow of interior gas and attitude motion of flight vehicle. The analysis result points out further research direction.关键词
