Abstract

The invention relates to a method of actively adjusting the balanced discharging of parallel connection tanks of a satellite two component propelling system. A simulation model of a propelling system is firstly established; the current system mixing ratio r0 is calculated according to the current system state data; then the pressure difference dpo1 of oxidant tanks (MON-A and MON-B) and the pressure difference dpf1 of incendiary agent tanks (MMH-A and MMH-B) are calculated through an optimization algorithm according to the target value of the balanced discharging of the parallel connection tanks; the target pressure of each tank is finally calculated through the optimization algorithm by taking the r0 as the target value and the dpo1 and dpf1 as the initial conditions; and the pressure of the tanks can be adjusted to the target pressure point by utilizing gas bypasses when a satellite is in orbit, so that not only is the balanced discharging of the parallel connection tanks adjusted, but also the system mixing ratio is not influenced.

Description

technical field [0001] The invention relates to a method for actively adjusting the balanced discharge of parallel storage tanks of a satellite dual-component propulsion system, which is suitable for the balanced discharge control of parallel storage tanks of the satellite dual-component propulsion system. Background technique [0002] For the satellite bicomponent propulsion system with parallel storage tank structure, an important issue is the propellant balance discharge capability. If the propellant discharge of two parallel storage tanks is unbalanced, when the propellant in one storage tank is emptied, the helium in the storage tank will be discharged if the propellant in one storage tank is emptied, so that the propellant in the propellant pipeline will be entrained. Thrusters and engines fail, and the satellite is at the end of its life. And the remaining propellant in the other storage tank will become heavy and cannot be used. For a satellite carrying 3000kg of p...
