中文摘要:在飞机系统地面模拟试验中,各类液体流量计及其流量显示仪表在液压、飞控、电源等系统试验中得到了广泛使用。从流量计连接方式、液体介质、流量显示方式三个方面分析了传统实验室的液体流量计计量方式所存在的弊端,同时,研究发现在各飞机试验系统中某些位置的液体流量计体积较大、安装复杂、不便拆卸。为解决上述问题,列举了3种在线校准液体流量计的方法,以避免流量计拆卸和安装,提高了工作效率,具有实用价值。
英文摘要:In the ground simulation testing of aircraft systems, varieties of liquid flow meters and their corresponding flow meters are widely used in the hydraulic, flight control, power supply and other system tests. This paper analyzes the traditional methods of laboratory measurement of liquid flow meters in three aspects which are the flow meter connection, the liquid medium, and flow display mode. The result shows that optimization of the traditional methods of laboratory measurement is urgent. At same time, some liquid flow meters are too large and complicated to install and disassemble. This paper presents three novel methods for calibration of liquid flow meter on line mode. These methods can avoid the disassembly and installation of the flow meter and improve the work efficiency, which have great practical value.
