Project Background：

A research institute of China Aerospace Science and Technology Group is the largest liquid rocket engine test research center in China, and in recent years, it has been undertaking civil engine tests.

In recent years, it has undertaken civil engine test tasks, and there is an urgent need to establish a set of independent and integrated measurement and control system, which can respond quickly to the needs of civil aerospace small-scale test tasks.

Shorten the test cycle while improving the reliability of test measurement and control, the implementation of which will greatly shorten the test mission cycle and improve test efficiency.

System Overview：

According to the generator, thrust chamber test demand, integrated training control system through the program control, manual control functions to complete the test process ignition and shutdown timing control, inlet pressure closed-loop control.

Sequence control of the test process, closed-loop automatic control of the inlet pressure, remote manual control of the products and test system controlled objects, real-time detection and recording of the commands and status of the control objects, and process control system.

real-time detection and recording of the commands and status of each control object, collection and recording of process status parameters, and display of the test process flow.

Main technical indexes：

◆Remote manual unit control of solenoid valves of product and test process system.

◆ It has the function of timing control of ignition and shutdown in the test process, and the precision of timing control:+0.01s.

◆ With closed-loop control function of product inlet pressure in the test process.

◆ With valve command and status signal acquisition function.

◆ It has the function of displaying process flow and valve status.

◆ High reliability.
