Abstract:	本研究以雷虎小型渦輪噴射引擎做一動態性能之量測與模擬驗證，以做為噴射引擎推力輸出之動態模型開發之基礎。研究初期量測此引擎之穩態性能，並建構輸入油門電壓之大小與燃油率、推力與轉速之關連。其結果在高轉速由80000rpm 至 120000rpm 之間接近一線性正比之關係式。在動態性能描述上採用Bode Plot 之頻率響應圖來建立引擎動態系統之轉移函數，透過其振幅之衰減與相位角之落後情形發現引擎轉速與推力之動態變化可以一階系統近似之，排氣溫則接近二階系統，而轉速與推力之反應幾乎同步，故以轉速 In this study, a micro gas turbine engine (Thunder Tiger P-15) is used to formulate its dynamic transfer function and compare with the test data to understand the dynamic response of an engine. The steady-state performance of the jet engine is studied fir
