Comprehensive balance discharge adjustment method for parallel tank propulsion system

Abstract

The invention discloses a comprehensive balance discharge adjustment method for a parallel tank propulsion system. The adjustment method comprises the following steps of (1), setting state parametersbefore adjustment, (2) performing oxygen tank balance discharge adjustment, and (3) performing fuel tank balance discharge adjustment. According to the comprehensive balance discharge adjustment method, the fact that the actual installation positions of spacecraft parallel tanks are discrepant is considered, and the mass of residual propellant in the two tanks after adjustment is independent of the mass before adjustment in the process of balance discharge adjustment of the parallel tank propulsion system so that comprehensive balance adjustment requirements of 'propellant mass * tank axis distance' can be realized and adapted. A main process and a sub process are fully parameterized, and an iterative cycle, an interpretation branch and other calculation methods are introduced so as to facilitate programming of the calculation program, thus reducing the time for determining control parameters.

Description

technical field [0001] The invention relates to a comprehensive balance discharge adjustment method of a parallel storage tank propulsion system, which uses the state parameters before system adjustment, the adjustment target parameters, the inherent design parameters of the storage tank, and the property parameters of the working medium as input quantities to accurately and quickly calculate the Integrated balanced discharge regulation requires an inflated tank and an inflated pressure. Background technique [0002] The two-component parallel tank chemical propulsion system of a spacecraft uses two working fluids, oxidizer and combustion agent, as propellants. The propulsion system generally consists of four parts: a high-pressure gas circuit module, a propellant storage module, an engine module, and an electronic circuit module. The function of the high-pressure gas circuit module is to store high-pressure gas and provide a stable flow of pressurized gas to the propellant...

AI Technical Summary

Problems solved by technology

The actual installation positions of the parallel storage tanks of different spacecraft will be different, so the remaining propellant mass of the two storage tanks after adjustment is independent from the mass before adjustment, and it is diverse, but it only adapts to the adjustment volume (after multiplying the density i.e. mass) is a special case of adjusting half of the volume difference of the remaining propellant in the first two storage tanks

[0007] 2) Not systematic and complete enough

This is reflected in two aspects. First, it does not give a method of determining the inflatable storage tank according to the state parameters before adjustment; second, it does not give how to determine the balance pressure of the two storage tanks after the balance discharge adjustment. The use method lacks certain guidance
