The invention discloses a propelling system and method, and a spacecraft. The propelling system comprises: a propelling body, wherein a propellant is arranged in the propelling body, and a nozzle is arranged on the propelling side of the propelling body; a driving assembly used for driving the nozzle to deform; and a control assembly used for controlling the driving assembly to drive the nozzle todeform according to the propelling task, and controlling the nozzle to spray the propellant after the deformation is finished and the spraying direction of the nozzle reaches the target spraying direction corresponding to the propelling task. According to the propelling system, the spraying direction is changed based on nozzle deformation, the structure is simplified, the machining and assemblingdifficulty is reduced, meanwhile, the spraying direction accuracy is effectively guaranteed, and the reliability of the propelling system is improved.

    本发明公开了一种推进系统、方法及航天器,其中,推进系统包括:推进本体,推进本体中设置有推进剂,其中,推进本体的推进侧设置有喷嘴;驱动组件,用于驱使喷嘴产生形变;控制组件,用于根据推进任务控制驱动组件驱动喷嘴产生形变,并在形变结束,使得喷嘴的喷向达到推进任务对应的目标喷向后,控制喷嘴喷射所述推进剂。根据本发明的推进系统,基于喷嘴形变改变喷向,精简化结构、降低加工装配难度的同时,有效保证喷向的准确度,提升推进系统的可靠性。
