Testing Technology Research of Flight Test Humidity Parameters

摘要:

为了确定飞机噪声测试结果的有效性及对噪声试飞数据进行修正,设计了一套完整的湿度参数气象测试方案；方案采用塞斯纳作为气象测试飞机,针对特定的气象测试需求,设计了盘旋上升的气象测试轨迹,并采用露点仪作为湿度测试设备；该湿度测试方案已经成功应用于ARJ21-700飞机噪声合格审定试飞,是国内相关飞行试验气象测试的首次尝试；实际的飞行试验结果表明,该方案能够准确、有效地测量飞行试验湿度等气象数据；该方案的成功应用,为今后相关的试飞测试提供了重要的参考价值。

Abstract:

In order to determine the validity of the test results of aircraft noise and correct the noise test data, a complete set of humidity parameters meteorological testing proposal has been designed. The proposal uses a Cessna aircraft as the weather test aircraft. For specific meteorological test requirements, spiraling weather test track has been designed, and the dewpoint meter has been used as the humidity test equipment. The humidity test proposal has been successfully applied in the noise certification test of the ARJ21-700 aircraft, and it's the first attempt in the domestic flight test weather testing. The actual flight test results show that in the flight test, the proposal can measure the meteorological data like humidity accurately and effectively. The successful application of the proposal has provided an important reference value for the flight test in the future.
