| 摘 要： | 目前发动机地面试验过程中的泵入口压力控制主要是通过控制介质贮箱内压力来实现的。介绍了大型液体火箭发动机研制试验中介质贮箱压力自动控制的一种新方法,这种方法集试验过程信号采集、动态工艺参数显示、上下限设定值显示、报警显示输出及自动控制为一体,减小了手动调节箱压继电器的操作误差,使系统的可靠性得到了很大程度的提高。

| Abstract: | The turbine inlet pressure during the rocket engine testing is mainly controlled by the propellant tank pressure.A new method to automatically control the propellant tank pressure in the testing of large-scale liquid rocket engine is introduced in this paper.This method is a combination of signal acquisition,parameter display,limiting indication,alarm display and automatic control.The operating error caused by the manual adjustment of tank pressure can be avoided by the method.The reliability of the testing system is improved a lot by this method. |
