航空发动机飞行任务剖面统计规律研究

Study of the Statistical Rules for Flight Mission Profiles of Aero-Engine

一般而言，可重复使用运载器的飞行任务剖面分为：垂直起飞、入轨、高超音速再入大气层、水平着陆几个阶段。

The vehicle has the following mission profile : vertical takeoff , boost-to-orbit , hypersonic re-entry and horizontal landing .

因此，可以根据主平面内各飞行任务剖面的第一、二主成分的分布情况直观地进行定性地分类。

The qualitative categorization can be done from the first and the second principal components distribution range in the principal plain .

采用某型教练机发动机的实测飞行数据，以飞行剖面转速循环中的主循环为当量疲劳损伤特征，进行了飞行任务剖面统计规律的研究，重点研究不同飞行员操作所造成的损伤差异。

Taking the equivalent fatigue damage of primary cycle as the character , the statistical rules for flight mission profiles of aero-engine are studied in this paper , mainly for different pilots ' control actions .
