【摘要】 流量是飞机环控系统试飞测试及飞机环控系统地面测试中的主要测试参数之一。论文设计了基于Lab VIEW的空气流量管标定装置,以音速喷嘴流量为标准,标定皮托管/均速管的流量系数,实现压力、压差、温度等各信号的采集与控制。经过试验数据可以看出,系统运行稳定、可靠。更多还原

【Abstract】 Flow is one of the main parameters in the flight test and the ground test of the airplane environmental control system. This paper designs air flow tube calibrated device based on Lab VIEW. In this thesis, the flow of sound velocity spray nozzle is regarded as a standard, the flow coefficient of the pitot/uniform velocity tube is calibrated. The system has automatic collection and control functions of pressure, differential pressure, temperature and other parameters. The test data indicates that the system is stable and reliable.更多还原
