Abstract

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.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a propulsion system, method and spacecraft. Background technique [0002] The propulsion system of the spacecraft is used as an actuator to provide control torque for the satellite to perform satellite attitude and orbit control tasks. Therefore, the reliability and control accuracy of the propulsion system are particularly important. [0003] In related technologies, the propulsion system of the spacecraft uses multiple nozzles to meet the multi-directional propulsion requirements, such as the 8-nozzle setting for the six-axis attitude control of the micro-nano satellite, and the 10-nozzle setting for another example. However, too many nozzle settings make The structure of the propulsion system is relatively complex, which is not conducive to processing and assembly, and the pipeline is too long, which easily increases the pressure loss along the process, resulting in reduce...
