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

Embodiment Construction

[0115] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0116] like figure 1 As shown, the spacecraft parallel storage tank chemical propulsion system generally includes 4 storage tanks, including 2 oxygen tanks and 2 fuel tanks, which are oxygen tank a MON-a, oxygen tank b MON-b, fuel tank a MMH- a. Fuel tank b MMH-b. The oxidant is discharged in parallel between the two oxygen tanks, that is, the downstream propellant outlets of oxygen tank a MON-a and oxygen tank b MON-b are respectively provided with self-locking valves LV5 and LV7 downstream of the storage tanks, and then connected together, and lead to the engine Eng An oxidant inlet to supply oxidant to the engine Eng. The upstream gas inlets of oxygen tank aMON-a and oxygen tank b MON-b are respectively provided with upstream self-locking valves LV1 and LV3 of the storage tanks, and then connected together.

[0117] The combustion agent is discharged in...

Abstract

The invention discloses a comprehensive balance discharge adjustment method of a parallel storage tank propulsion system. The present invention considers the actual situation that the actual installation positions of the parallel storage tanks of the spacecraft will be different, and the mass of the remaining propellants in the two storage tanks after adjustment in the balanced discharge adjustment process of the proposed parallel storage tank propulsion system is independent of the mass before adjustment. It can meet the comprehensive balance adjustment requirement of "propellant mass × storage tank axis center distance". The main process and sub-processes are fully parameterized, and calculation methods such as iterative loops and interpretation branches are introduced to facilitate the compilation of calculation programs, thereby 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...
