The invention discloses a regional cooperative type two-phase mixed space propelling system and method. The regional cooperative type two-phase mixed space propelling system comprises a propellant supply system and a chemical-electric composite thruster. A propellant II in the propellant supply system can be used as an electrical substance; the chemical-electric composite thruster comprises an electric thruster and a chemical thruster which are coaxially arranged from inside to outside or from outside to inside; 4m chemical thrust subareas are uniformly distributed in a throat pipe and a diffuser pipe of the chemical thruster along the circumferential direction; 2m baffles capable of rotating are arranged at the front end of the throat pipe; the electric thruster can be partitioned or not partitioned as required; when the grid electrode is partitioned, 4n grid electrode insulating partition plates are additionally arranged in the grid electrode, so that the grid electrode is uniformly partitioned into 4n grid electrode sub-regions in the circumferential direction, and each grid electrode sub-region can be independently subjected to power-on control. According to the invention, on the premise of sharing one set of propellant supply system, alternate work of two modes of chemical propulsion and electric propulsion can be realized; and the thrust can be controlled in a regional manner, so that the requirements of different space propulsion tasks are met.
本发明公开了一种区域协同式两相混合空间推进系统及推进方法,包括推进剂供给系统和化电复合推力器;推进剂供给系统中的推进剂二能作为电工质;化电复合推力器包括从内至外或从外至内同轴布设的电推力器和化学推力器;化学推力器的喉管和扩喷管内沿周向均匀布设有4m个化学推力子区;在喉管前端布设2m块均能转动的挡板;电推力器根据需要可以分区或不分区;当分区时,通过在栅极中增设4n块栅极绝缘隔板,从而将栅极沿周向均匀分隔为4n个栅极子区,每个栅极子区能单独进行通电控制。本发明能在共用一套推进剂供给系统的前提下,实现化学、电推进两种模式交替工作;还能实现对推力分区域式控制,从而满足不同空间推进任务的需求。
