The invention provides an inertial electrostatic confinement air suction type electric thruster which is characterized by being composed of an anode grid mesh, a cathode grid mesh, a grid mesh fixing piece, a shell, a transmission set and a gas distributor. Wherein the anode grid mesh and the cathode grid mesh are connected together through the grid mesh fixing piece; the shell is composed of a shell front end, a shell rear end and a thruster fixing piece, the thruster is sealed, and the thruster is fixed to a satellite through the thruster fixing piece; the transmission set is an opening structure of a thruster shell and is controlled by a motor, the motor drives two connecting rods to open the thruster shell when air suction is needed, and the shell is closed when air supply is needed; and the gas distributor uniformly transports the introduced gas into the thruster. The working mode of the inertial static constraint thruster is added, so that the thruster is better applied to a low-orbit satellite, the application range of the thruster is widened, and the working life of the thruster is prolonged.
本发明提出一种惯性静电约束吸气式电推力器,其特征在于:由阳极栅网、阴极栅网、栅网固定件、外壳、传动组以及气体分配器组成;其中,阳极栅网和阴极栅网通过栅网固定件连接在一起;外壳由外壳前端、外壳后端和推力器固定件组成,对推力器进行封闭,通过推力器固定组件使推力器固定在卫星上;传动组是推力器外壳的开启结构,通过电机控制,当需要吸气时电机驱动两个连杆打开推力器外壳,需要供气时则关闭外壳;气体分配器将通入的气体均匀运输进推力器中。本发明增加了惯性静电约束推力器的工作模式,使推力器更好的应用于低轨道卫星,增加了推力器的使用范围与工作寿命。
