转移轨道航天器深层充放电效应仿真分析
Simulation of Deep Dielectric Charging for Transfer Orbit Satellite
摘要
Abstract
In order to acquire the charging characteristics and assure the long-period stability of electronic devices in transfer orbit satellites, a model is established based on FLUMIC model of ESA about electrons in radiation belt, which is used in dynamic electron environment evaluation. A model based on RIC model and Geant4is also provided in computer simulation to analyze the mechanism and physical process of internal charging. The features of GTO and phasing orbit internal charging are analyzed for the first time. It can be concluded that transfer orbit satellites experience severe environment change when passing through the radiation belt, while instantaneous flux shows obvious fluctuations. This fluctuation can increase the charged potential and the risk of internal charging. It is shown that the internal charging risk in the center of radiation belt is higher than that in other areas in normal case.关键词
