Abstract:	本研究建立小型渦輪噴射引擎向量推力之模型，透過水平單擺系統之穩定平衡做為驗證與分析之依據。由數值模型分析之水平單擺臨界振幅與震盪週期與實驗結果相當一致。在控制器之設計上採用無切換方式其系統反應較迅速可進行大角度之俯仰操作其超越量非常小，但在抗干擾之回復能力較有切割之控制器差。利用小型風洞二維向量噴嘴之測試系統，進行噴嘴開口角度、噴嘴板長與風速之側向流速量測，其結果顯示在固定折流板長度下，有一最佳切線速度與軸向速度比使其系統頻寬最大，且較高之噴嘴開度下其系統有超越量之輸出，相同之噴嘴開度 A dynamic model of a thrust-vectoring engine was proposed. The stability of a horizontal pendulum was used to validate the current model through the feedback of the vectoring thrust. The oscillation angle of the limit-cycle between numerical model and tes
