摘要
Abstract
With the development of new generation launch vehicles, a high pressure staged-combustion liquid oxygen/kerosene propellant rocket engine with thrust level of 120 t will be used exten- sively. The design of the pressurization system is one of the key technologies of new generation launch vehicles. Based on the review of pressurization system used on the domestic and foreign launch vehicles, a new tank pressurization system of launch vehicle used on the liquid oxy- gen/kerosene engine was studied, which used helium gas (heated helium gas in liquid oxygen tank and room temperature helium gas in kerosene tank) as the pressurization gas, and tank pressure and helium flow were controlled by tank pressure sensors and electromagnetic valves. Also a full size experimental research and theoretical analysis of heated helium pressurization system for liquid oxygen tank was conducted. The experiment and analysis results indicate that the pressurization system is feasible.关键词
