| 摘要: |
| 系统地研究了教练机航空发动机设计载荷谱的推导方法，主要包括：（1）基准机的选取与现役发动机载荷谱的空测、统计；（2）新机发动机飞行剖面的预测；（3）新机发动机设计任务循环的编制等三大步骤。提出的方法具有一定的通用性，可以推广到其它类型的发动机设计载荷谱研究。 |

| Abstract: |
| The method of load spectrum derivation for trainer engine design is presented. The main steps are: selecting reference aircraft engine, measuring active engine load spectrum, predicting new engine flight mission profiles and drawing up design duty cycles of the new engine’ As a general method, it can be used for other typical engines to certain extent. |
| Key words: Training aircraft Aircraft engine Load spectrum |
