An ionic liquid electrospray thruster suitable for a high-pressure storage and supply module is characterized in that one end of a thruster shell is sleeved with an emitting electrode to form a cavity structure; the thruster shell is fixedly connected with an electromagnetic valve butt flange through an insulating column; the capillary tube is used for spraying a propellant into the cavity structure to form a fog cone; bubbles are separated out from the propellant remaining in the capillary tube under the vacuum condition, and the bubbles are utilized to divide the propellant in the capillary tube into a plurality of cavities, so that an insulation effect is achieved; the thruster shell is fixedly provided with an extraction electrode, and the extraction electrode is grounded and does not make contact with the emitting electrode; the emitter is fixedly connected with an emitter electrode; and a vent hole is formed in the thruster shell. The electrospray thruster can be in butt joint with a high-pressure propellant storage and supply system to supplement propellants, the service life of a single thruster is prolonged, and optimal utilization of the propellants in a propelling system is achieved. The butted propellant storage and supply system disclosed by the invention can continue to use parts such as an existing non-toxic single-component propellant storage box, an electromagnetic valve and the like.
一种适用于高压贮供模块的离子液体电喷雾推力器,包括:推力器外壳的一端套装发射极,形成腔体结构;推力器外壳通过绝缘柱固定连接电磁阀对接法兰;毛细管用于向腔体结构内喷射推进剂形成雾锥;毛细管内部残留的推进剂在真空条件下析出气泡,利用气泡将毛细管内的推进剂分隔为多个空腔,起到绝缘作用;推力器外壳上固定安装有抽取极,抽取极接地处理且与发射极之间不接触;发射极上固定连接有发射极电极;推力器外壳上加工有通气孔。本发明所涉及的电喷雾推力器可对接于高压推进剂贮供系统以补充推进剂,延长单台推力器的寿命,实现推进系统中推进剂的优化利用。本发明对接的推进剂贮供系统可沿用现有无毒单组元推进剂贮箱、电磁阀等零部件。
