The invention discloses an array type micro-cathode discharge propulsion system in a three-dimensional vector direction. The array type micro-cathode discharge propulsion system comprises a power supply power control unit, a plurality of thrusters and a change-over switch module; the thrusters are fixedly installed at the edges in a cubic star structure, and the thrust output directions of the thrusters are the same as the length directions of the corresponding edges; at most two thrusters are installed on one edge of the cubic star structure, and the output thrust directions of the two thrusters are opposite; the power supply power control unit receives power supplied by a whole satellite power supply, receives a control signal transmitted by a whole satellite control system, and transmits switch enabling to the change-over switch module according to the control signal; and the change-over switch module receives the switch enabling transmitted by the power supply power control unit, and switches on or off of the thrusters according to the switch enabling. According to the array type micro-cathode discharge propulsion system, the thrust and the vector direction can be controlled onone module, and the attitude and orbit of the satellite can be directly and flexibly regulated and controlled without turning the direction of the satellite and other operations.

    一种三维矢量方向的阵列式微阴极放电推进系统,包括:电源功率控制单元、多个推力器及切换开关模块;推力器固定安装在立方星结构内的棱边处,推力器输出推力的方向与对应棱边的长度方向相同;立方星结构的一条棱边上最多安装两个推力器且两推力器的输出推力方向相反;电源功率控制单元接收整星电源的供电,电源功率控制单元接收整星控制系统传输的控制信号,根据控制信号向切换开关模块传输开关使能;切换开关模块接收电源功率控制单元传输的开关使能,根据开关使能,切换推力器的开关闭合或断开。本发明在一个模块上就可以实现推力大小以及矢量方向的控制,不需要卫星调转方向等操作就可以直接灵活实现卫星姿态及轨道的调控。
