新一代运载火箭闭式增压控制系统设计与实现

Design and Implementation of a Closed-Loop Pressurization Control System of New Generation Launch Vehicle

提出一种液体运载火箭全数字闭式增压控制系统方案,并对系统原理、关键控制设备进行了论述,提供了闭式增压的控制方法。新一代运载火箭工程应用与试验结果表明,全数字闭式增压控制系统稳定可靠,方案可行,可在液体运载火箭工程设计中推广应用。

In this paper, the scheme of a closed-loop pressurization digital control system of liquid propellant launch vehicle is proposed. And then, the system working principle and its crucial control equipments are discussed. Subsequently, the closed-loop pressurization control methods are preseneted in detail. The application and test results of chinese new generation medium launch vehicle show that the closed-loop pressurization digital control system is stable and reliable, which can be extensively applied in liquid propellant launch vehicle.
