Problems solved by technology

[0005] Since the process of propulsion and supplementation is divided into multiple steps and carried out sequentially, there is a strong coupling relationship between the steps before and after the supplementation process, and individual supplementary links need special measurement and control conditions to support, the traditional flight program design method has been unable to meet the requirements of on-orbit flight procedures. Requirements for the Implementation of Propellant Replenishment Missions

Abstract

The invention relates to a flight programming method for the on-orbit propellant replenishment of a spacecraft, comprising the following steps: a. dividing the flight program of the spacecraft in theprocess of propellant replenishment into a plurality of sub-program modules; b. determining a corresponding subroutine module according to the type and quantity of the replenishment tank determined inthe propellant replenishment scheme; and c. sequentially executing the corresponding subroutine modules according to the time axis order. The flight program design method for on-orbit propellant replenishment of the spacecraft according to the invention can solve the problem that the specific flight control implementation is difficult due to the mutual restraint among the propulsion replenishmentsub-events, and at the same time, the workload of the ground flight control personnel is greatly reduced, and the implementation time of the propulsion replenishment is shortened.

Description

technical field [0001] The invention relates to a flight program design method for on-orbit propellant supplementation of spacecraft. Background technique [0002] Propellant on-orbit replenishment technology is one of the key technologies necessary for the construction of a space station. The compressor establishes a low-pressure environment for the capsule storage tank, and uses the pressure difference to transfer the propellant carried by the cargo spacecraft to the capsule storage tank of the space station. [0003] The storage tanks configured by the spacecraft include fuel storage tanks and oxidant storage tanks. On-orbit, it is determined whether to supplement the fuel storage tanks or oxidant storage tanks according to the remaining propellant of each storage tank, and calculate the required additional storage tanks. Amount of propellant added. The on-orbit replenishment process for the fuel tank and the oxidant tank is the same, and the replenishment process mainl...
