Abstract:
The vacuum pressure is the key parameter in altitude simulation test of liquid rocket engine. As for the testing system of 76 km high altitude environment, the accuracy of vacuum pressure measurement is an important basis for determining if the engine can be ignited. The measurement technology of vacuum pressure used in the high altitude environment test of 76 km is introduced in the paper. The sectionalization measurement methods of vacuum gage in testing environment, installation, measurement process and calibration technology on spot of vacuum gage are introduced in this paper.
