Analysis on space plume contamination of retro-rocket combustion products
摘要
Abstract
The separation between satellites and rockets is usually provided by a reliable separation power from the retro-rocket mounted around the rocket body. During the working progress of retro-rocket, the solid propellant burns to the high temperature and high pressure gas which is ejected from the nozzle outlet and results in the separation force. However, the emitted gas would form a significant contamina-tion field of gas mixture plume in the vacuum environment due to its change from a high-density contin uous medium to a rare gas free molecular flow with very low density, which could have a negative impact on the cleanliness of the satellite surface. In this paper, the parameters affecting to the formation of the plume contamination field were investigated for a certain type of retro-rocket. With the numerical simula-tion of the spatial plume, the installation position and angle of the retro-rocket were obtained, as well as the corresponding relationship between the two factors and the spatial plume contamination. The research results provide a reference for the corresponding separation design between the satellite and the retro-rocket.关键词
