Description

technical field [0001] The invention relates to a spacecraft propellant replenishment simulation simulation test system. Background technique [0002] The on-orbit propellant replenishment technology is one of the key technologies necessary for the construction of the space station. The propellant replenishment system currently used on the International Space Station is a Russian replenishment technology. The basic process is: Cargo spacecraft carrying propellant (replenishment Plus spacecraft) is docked with the space station (the added spacecraft), and the space station establishes a low-pressure environment for the bellows tank through its own compressor, and uses the pressure difference to transfer the propellant carried by the cargo spacecraft to the space station bellows tank. [0003] At present, my country is developing spacecraft propellant on-orbit replenishment technology. Among them, the implementation of propellant replenishment information exchange protocol, pr...

AI Technical Summary

Problems solved by technology

The existing technical means have the following problems: ① In the ground test stage, the most realistic verification effect can be achieved by conducting special tests on the supplementary information protocol and supplementary flight procedures in the state of the whole device, but this method requires a lot of manpower and time cost, especially when there are problems in the supplementary information protocol and program design, it will lead to the repetition of special tests and increase the workload; The transmission and the corresponding telemetry changes are simply simulated, but the slowly changing parameters such as temperature, pressure, and remaining volume, which play an important role in the judgment of key stages and key events in the replenishment process, cannot be truly simulated, and at the same time cannot be simulated for the replenishment process. Simulation of failure modes, lack of special supplementary simulation verification system

[0005] For the traditional ground test verification method, when there are problems in the supplementary information protocol and program design, the test will be repeated and the workload will be increased; at the same time, the existing ground flight control exercise system can only simply simulate the change of telemetry parameters , and the actual on-orbit state of propellant replenishment is quite different
