The invention provides a spacecraft thruster fault handling method. The spacecraft thruster fault handling method comprises the steps that a small geostationary orbit satellite is transferred to a geostationary orbit from an earth transfer orbit through three stages; the small geostationary orbit satellite comprises an orbital transfer chemical thruster, an attitude control chemical thruster and an electric thruster, and in the second stage of transfer of the small geostationary orbit satellite, a fault coping scheme is started according to a fault coping strategy of'first electric propulsion, then orbital transfer chemical thruster and then attitude control chemical thruster '; the fault coping scheme comprises the steps that when the electric thruster breaks down, the orbital transfer chemical thruster is started; and when the electric thruster and the orbital transfer chemical thruster both break down, the attitude control chemical thruster is started.
本发明提供了一种航天器推力器故障应对方法,包括:通过三个阶段将小型地球静止轨道卫星从地球转移轨道转移至地球静止轨道;所述小型地球静止轨道卫星包括变轨化学推力器、姿控化学推力器及电推力器,其中,在小型地球静止轨道卫星转移的第二阶段,依据“先电推进、再变轨化学推力器、再姿控化学推力器”的故障应对策略启动故障应对方案,故障应对方案包括:当电推力器故障时,开启变轨化学推力器;当电推力器和变轨化学推力器均故障时,开启姿控化学推力器。
