本文结合民机航空发动机的性能确定试验,讨论了目前国外所采取的性能确定流程及其特点,并指出了目前国内基于相似理论的高度-速度特性以及节流特性试飞存在的缺陷,突出了国外性能确定方法的优点。结合国产ARJ21-700飞机发动机飞行推力确定试飞,阐述了美国通用电气公司(GE)针对CF34-10A发动机所采用的性能确定流程,介绍了基本方法和思路,为今后国内开展民机、军机的性能确定试飞提供借鉴和参考。
In this paper, the test of performance determination of civil aircraft engine is discussed. The current performance determination process and its characteristics taken abroad are discussed. At the same time, the current domestic high-speed characteristics based on similarity theory and the throttling of throttle feature are discussed. The advantages of the performance determination method. Combined with the thrust test of the domestic ARJ21-700 aircraft engine to determine the test flight, this paper expounds the performance determination process adopted by the General Electric Company (GE) for the CF34-10A engine, introduces the basic methods and ideas for future domestic civil aircraft and military aircraft performance Determine the test flight to provide reference and reference.
