中文摘要:
      直升机(飞机)动力舱灭火系统进行试验时需要准确测量灭火剂浓度随时间变化情况。利用空气中不 同百分比的灭火剂流经多孔塞产生不同流阻的原理,研究并标定流阻与灭火剂浓度的关系;研制灭火剂浓度测 试设备,并将该设备应用于多个型号的地面试验。结果表明:该设备响应灵敏,能实时反应动力舱内灭火剂浓 度的变化情况,满足直升机(飞机)动力舱灭火系统地面模拟试验要求。
英文摘要:
      In order to solve veracious measurement about the variety of extinguishing agent concentration along with time in the ground simulation test of helicopter/aeroplane powerplant compartment, the special extinguishing agent concentration measurement has been developed. The project includes the principle, the system composition, the rapid air heating, the differential pressure generation and the multichannel synchronous control. The measurement has been successfully used in the ground simulation test of several helicopters, the datum show the response of measurement is real-time about the variety of extinguishing agent concentration along with time, because of response sensitivity. it can be satisfied with the requirement of ground simulation test in the fire extinguisher system of helicopter/aeroplane powerplant compartment.
