| 中文摘要: |
| 为提高中等推力航空发动机工作性能，对其喷口控制方法进行对比分析，并通过台架试验对喷口等落压比和喷口转差
控制方法进行试验验证。结果表明：相比于等落压比控制方法，转差控制方法更利于精确调整发动机在节流状态下的性能，且可降
低发动机耗油率，更适合作为中等推力发动机的喷口控制计划；对全包线的各典型点进行验证，转差控制方法仍能满足发动机的控
制性能要求，且实施方便、效果好。 |
| 英文摘要: |
| In order to improve the working performance of medium thrust aeroengine，the comparative study on nozzle control methods
were carried out，and the control method of equal pressure drop ratio and slip control of nozzle was verified by bench test. The results show
that the slip control method is more conducive to accurately adjusting the performance of the engine in throttling state than the equal
pressure drop ratio control method，and can reduce the specific fuel consumption of the engine，which is more suitable for the nozzle control
plan of the medium thrust engine. The typical points of the full-envelope are verified，and the slip control method can still meet the
requirements of engine control performance，and the implementation is convenient and effective. |
