The invention relates to a system and a method for blowing off residual propellant in an on-orbit supplementary pipeline of a spacecraft, wherein the system for blowing off residual propellant in an on-orbit supplementary pipeline for a spacecraft comprises: a gas supply unit, the The air supply unit is connected with the propellant output pipeline; the receiving unit is connected with the propellant receiving pipeline; the exhaust unit is connected with the propellant receiving pipeline, along In the direction of propellant replenishment, the connection position between the exhaust unit and the propellant receiving pipeline is before the connection position between the receiving unit and the propellant receiving pipeline. The gas supply unit and the receiving unit are used to recover the propellant in the propellant supply pipeline, and the purpose of fully utilizing the residual propellant in the pipeline is achieved. The propellant is not discharged outside the cabin, which effectively reduces the interference generated when cleaning up the residual propellant in the supplementary pipeline, reduces the impact on the attitude of the spacecraft, and avoids polluting the equipment outside the cabin and blocking the exhaust port.
Description
technical field [0001] The invention relates to the field of aerospace, in particular to a system and method for blowing off residual propellant in an on-orbit supplementary pipeline of a spacecraft. Background technique [0002] The on-orbit propellant replenishment technology is the core technology of the space station project and a necessary technology for the long-term operation of the space station. Russia has realized on-orbit propellant filling since 1978, and has successfully completed multiple on-orbit replenishment, while the United States has started research on on-orbit replenishment technology since the early 1980s, making this technology gain Fully developed and successfully implemented on-orbit demonstration verification. [0003] On-orbit propellant replenishment refers to two spacecraft with independent flight functions, establishing a propellant delivery channel in orbit, and transporting propellant from the propellant tank of one spacecraft to the propell...
