    • 本論文旨在研究三軸承旋轉管尾噴嘴(3-Bearing Swivel Duct, 3BSD)的設計與應用，這是實現垂直/短場起降(Vertical/Short Take-Off and Landing, V/STOL)飛機的關鍵技術之一。在現今3D列印技術日益成熟的背景下，本研究通過建立3BSD的CAD建模，模擬其旋轉動作，並使用3D列印技術進行模型製作與組裝，探索其設計原理和應用前景。
    首先，本文回顧了3BSD尾噴嘴的發展歷程及其在不同飛行器上的應用，並分析了結構和工作原理。接著，詳細介紹了3BSD尾噴嘴的設計過程，包括噴嘴形狀和尺寸的設計、驅動結構的設計以及運作模擬。在模擬部分，我們使用SOLIDWORKS Motion和Flow Simulation軟體對3BSD尾噴的運動和流體動力學進行了模擬分析，研究了旋轉角度及對流場、流速和壓力分佈的影響。研究結果顯示，3BSD尾噴嘴在不同旋轉角度下能有效調整推力方向，滿足V/STOL飛機的需求。通過3D列印技術製作的模型成功展示了3BSD尾噴嘴的結構和功能，為未來V/STOL飛機的設計提供了有價值的參考。

    This thesis aims to study the design and application of the Three-Bearing Swivel Duct (3BSD) nozzle, which is a key technology for achieving Vertical/Short Take-Off and Land-ing (V/STOL) in aircraft. With the rapid advancement of 3D printing technology, this re-search explores the design principles and application prospects of the 3BSD nozzle by estab-lishing a CAD model, simulating its rotational motion, and creating a physical model through 3D printing.

    Firstly, the thesis reviews the development history of the 3BSD nozzle and its applications in various aircraft, analyzing its structure and working principles. Then, it details the design process of the 3BSD nozzle, including the design of its shape and dimensions, the design of its drive structure, and the operation simulation. In the simulation section, SOLIDWORKS Motion and Flow Simulation software were used to perform dynamic and fluid dynamics simulations of the 3BSD nozzle, studying the effects of rotational angles on flow field, ve-locity, and pressure distribution. The research results indicate that the 3BSD nozzle can ef-fectively adjust thrust direction at different rotational angles, meeting the requirements of V/STOL aircraft. The model created using 3D printing technology successfully demonstrated the structure and functionality of the 3BSD nozzle, providing valuable references for the de-sign of future V/STOL aircraft.
