摘　　要：准确测量65号军用航空冷却液流量是液体冷却系统试飞测试中的难点之一。本文结合某型飞机液冷系统试飞测试中所采用的压差流量测量法,对65号冷却液流量与压差的对应关系进行研究,总结出压差法测量制冷液流量应遵循的基本原则。It is difficult to measure the flow of No.65 coolant exactly in the flight test of liquid cooling system. Using pressure difference method to measure the flow of No.65 coolant is doable during a certain flight test, and the relationship between flow and pressure difference is studied deeply. The basic principle of flow measurement based on pressure difference method is summarized.
