摘要
Abstract
Pressure is one of the key parameters in the ground test of rocket engines and must be measured accurately. The principle of low-temperature pressure parameter measurement, calibration method and problems existing in the LOX/kerosene rocket engine test are introduced in this paper.The zero drift and slope change of pressure sensors in low temperature are discussed and researched emphatically in the paper. Solutions of the problems and data modification methods are proposed on the basis of problem analysis. This has laid the foundation for improving accuracy of pressure measurement in low temperature.关键词
