| Abstract: |
| A thruster configuration and optimization method for GEO satellite is proposed in this paper. All thrusters are installed on the back panel of satellite, which is not only compatible with the design of satellite subdivision structure, but also able to provide a large installation room for the payloads and components carried by the satellite. Chemical thruster and electric thruster were selected because they have complementary advantages and can effectively reduce propellant consumption. The working mode and tasks of the thruster were analyzed in detail for thruster configuration, which was optimized in order to minimize propellant consumption. Lastly, a GEO satellite thruster was configured and optimized using this method, with results showing that the method is feasible and effective, and consequently has value for engineering applications. |
