The invention belongs to the field of thrusters, and particularly relates to a novel electrostatic thruster. The electrostatic thruster mainly comprises a supporting device, an electrode grid, a liquid storage device, an emitting electrode and a transmission pipe, the emitting electrode is made of a porous material, comprises emitting tips and is arranged on the outer top of the liquid storage device, and the electrode grid comprises a plurality of through holes evenly distributed in the electrode grid. The through holes are in one-to-one correspondence with the emitting tips; in the prior art, the propellant is naturally sucked out to the emitting tips by directly utilizing the porous material attribute of the emitting electrode, but the conveying pipe is arranged and arranged at the preset position, preferably, the propellant is conveyed to the position near the emitting tip from the interior of the liquid storage device through the conveying pipe, the capillary stroke of the propellant in the porous material is reduced. Therefore, the propellant can be further sucked out and rapidly conducted to the emitting tip through the capillarity, the propelling efficiency is improved, and the ionization degree can be conveniently and automatically controlled.

    本发明属于推进器领域,尤其涉及一种新型静电推力器。本发明的静电推力器主要包括支撑装置、电极栅、液体存储器、发射极和传输管,所述发射极由多孔材料制成,其包括发射尖端,并且设置于液体存储器的外顶部,所述电极栅包括在其上均匀分布的多个贯穿孔,该贯穿孔与所述发射尖端一一对应;现有技术均直接利用发射极的多孔材料属性使推进剂自然吸出至发射尖端,但本发明设置传输管并将其设于预定位置,优选通过传输管将推进剂从液体存储器内运输至发射尖端附近,减少推进剂在多孔材料中的毛细行程,以便于进一步利用毛细现象使推进剂被吸出并快速传导至发射尖端,提高了推进效率且便于自动化控制电离程度。
