| Abstract: | Zero-dimensional closed-loop simulation is implemented to one single-shift jet engine through simulation test-bed. The effect of turbine efficiency changing on turbo-engine's characteristic, such as thrust, rotating speed and SFC, is discussed in three different control mode, and some results are compared with test data. |

| Keywords: | Turbojet engine Numerical simulation Turbine effectiveness Closed loop control |
