简单控制规律下涡喷发动机特性的研究

Research on characteristics of turbojet engine with simple control program

研究了用于无人飞行器上使用的小推力级涡喷发动机在简单控制规律下的多种重要特性。通过计算机模拟方法 ,重点研究某型发动机的设计点性能装订方法、不同进口温度条件下发动机的稳定工作裕度以及发动机能够适应的飞行包线 ,并揭示了发动机的一些潜在的缺点。计算结果在发动机设计。

The characteristics of low-thrust turbojet engine with a simple control program were studied. Based on the engine performance simulation, the method of setting the maximum engine performance and the effect of environmental temperature on engine performance and the range that the engine is running steadily and reliably was studied. Some disadvantages of the engine were described. The calculating results are useful for engine usage and testing.
