Abstract: 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 running steadily and reliably was studied.Some disadvantage of the engine were described. The calculating results are useful for engine using and testing.

Key words: Turbojet engine;Engine control;Control program;Engine characteristics.
