摘要
Abstract
An Ultrasonic Flow Meter (UFM) was designed for accurate propellant gauging.Based on the research of transit time measurement, the requirements for pipe structure design were proposed.Computational Fluid Dynamics CCFD) was used to simulate the velocity distribution of four different pipe structures, and an optimal pipe structure was designed based on the (JFD result.Chopper stabilized comparator in the signal processing electronics ensured the time measurement accuracy by using the threshold value comparing technique.After calibration, the ultrasonic flow meter can achieve an accuracy of 0.1% for range 0 -150 g/s.In order to test the function of the flow meter in orbital refueling, a ground simulation experiment was carried out.The result of the ground simulation experiment shows that the implementation of ultrasonic flow meter is practical for orbital refueling and quite necessary for performance observation during the refueling process.关键词
