摘　　要：爬升性能是衡量飞机性能的重要指标之一。在解读适航规章及咨询通告的基础上,首先,对DA42NG机型光洁构型下的爬升性能实施了飞行试验研究,完整展现了飞行试验方法及数据处理过程。其次,将飞行手册中列出的爬升性能参数修正到飞行试验时的飞机状态和大气条件。最后,将飞行试验数据与飞行手册数据进行了比对。研究结果表明,飞行试验测量的最佳爬升速度略大于飞行手册数值,而最佳爬升率略小于飞行手册数值。测量数据与手册数据的差异可接受,结果符合预期。试验及数据处理方法可为同类飞机适航审定及验证试飞提供借鉴和参考。Climb capability is a key indicator of aircraft performance.Firstly,based on interpretation of airworthiness regulations and advisory circular,flight test is conducted on climb performance of DA42NG clean configuration to present whole procedure of test method and data processing.Secondly,climb performance parameters in Airplane Flight Manual are revised respectively according to flight status and atmospheric conditions simultaneously.Finally,flight test data and flight manual data are compared.The best climb speed measured in flight test is slightly higher than that listed in Airplane Flight Manual,while the best climb rate is slightly lower.Analyses of accuracy-influencing factors show that differences between the measured data and manual data are acceptable.Research results are in line with prediction.The test and data processing methods can provide reference and guide for airworthiness certification and verification,as well as testing flight of similar of types aircraft.
