摘要
介绍了液氧煤油发动机试验中低温压力参数测量原理、校准方法及存在的问题,重点对低温压力传感器在低温条件下零位漂移问题进行了探讨和研究,提出了基本解决途径和数据修正方法,为提高低温压力的测量准确性奠定了基础。
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.
