The invention discloses an earth static rail communication satellite prototype sample star electric propulsion system comprising an electric star electric propulsion system and a structural star electric propulsion system. The electric star electric propulsion system comprises an ion thruster unit S1, an ion thruster unit S2, an ion thruster vector regulating mechanism S, a pressure regulating module, a flow control module N1, a flow control module N2, a flow control module S1, a flow control module S2, an electric propulsion power supply processing unit 1, an electric propulsion power supply processing unit 2, a pipeline and a cable. The earth static rail communication satellite prototype sample star electric propulsion system disclosed by the invention can be used for realizing function check through a relatively simple prototype sample electric propulsion system; the configuration and technical state of the prototype sample star electric propulsion system are determined according to check requirements of electric propulsion performance, and a scheme which is simplified as much as possible is utilized on the premise of sufficiently carrying out test program check; the prototype sample star electric propulsion system can finish the function check of all communication satellite electric propelling systems, besides an ignition function of the thruster; and the ignition function of the thruster needs to be carried out in vacuum, and the whole star test does not have a test state.
Description
technical field [0001] The invention relates to a prototype satellite electric propulsion system of a geostationary orbit communication satellite. Background technique [0002] The development of the initial sample of the satellite includes the development of the electrical star and the structure star. The purpose of developing the initial sample satellite is to verify the correctness of the satellite design scheme, and to solve the exposed design problems. [0003] Electric propulsion technology is an advanced spacecraft propulsion technology that uses electric energy to accelerate the propellant to achieve high specific impulse. Under the same propellant quality, the total impulse output of electric propulsion is several times or even dozens of times that of conventional chemical propulsion systems. . The high specific impulse advantage of electric propulsion can reduce the quality of the satellite platform, increase the lifespan, and increase the payload capacity. On t...
