- Abstract:
- !![Research on measurement of LOX mean flow rate] in the LOX/kerosene rocket engine test was conducted. The measurement concept and method of volume and mass flow rate calculation were introduced in this paper. In order to reduce the system error of turbine flow meter, the flow meter should be calibrated with the data of LOX mean flow rate measured at cryogenic condition. The principle for calibration is the mass conservation law. Based on the mean volume flow rate measured in the propellant tank, the equation of flow rate performance for the turbine flow meter can be solved, thus flow rate of the LOX be obtained.
