摘　　要：为满足某型号氢氧火箭发动机大流量气流试验要求,通过深入分析和调研,决定采用阿牛巴质量流量计进行气体流量测量。介绍了阿牛巴流量计的结构组成、工作原理,对流量计的管道安装、流量数据计算进行了详细描述,将阿牛巴流量计与科里奥利质量流量计的测试数据进行比较,结果表明阿牛巴流量计在试验中具有良好使用效果。最后对阿牛巴流量计的性能特点、应用前景进行了论述。To meet the requirements of large air flow test for a LOX/LH2 rocket engine, Annubar mass flowmeter is adopted to measure the air flow on the basis of comprehensive analysis and re-search. The structure and working principle of the Annubar flowmeter are introduced. The flowmeter installation on pipeline and its flow data calculation are described in detail. The test data of Annubar flowmeter and Corioris mass flowmeter is compared, and also the application effect of Annubar flowmeter in the air flow test is illustrated in this paper. The performance characteristics and applica- tion prospect ofAnnubar flowmeter are discussed.
