Abstract
The regulated pressurization system is commonly employed to ensure constantpropellant tank pressure in order to maintain stable working status of thrusters.A calculation modelfor the cold gas and warm gas regulated pressurization systems is founded.The model can calculate the parameters of a whole pressurization system and its components. For the given mission requirements ofa liquid attitude and divert system, based on the calculation model and genetic algorithm, the optimizationselectioncan be conducted and the best regulated pressurization system scheme can be selected.According to a typical example,the optimization selection process was demonstrated to select the best regulated pressurization system.The results show that the working capacity,envelope volume, working pattern, thermal management, storage performance, technology maturity, especially the propellant tank pressure have great influenceson selection of pressurizationsystem schemes.The method of this paper maybe used as a reference for practical design of the regulated pressurization system for liquid attitude and divert propulsion systems.
