摘要

對於潛艇操作性的優化，除了在船體、帆罩等大區域進行改變，透過小區域的改變，達到性能優化之效果相對地更加符合實際需求。本研究改變尾舵基座之構型，比較X舵與十字舵在船體-尾舵-螺旋槳交互作用下的流場與數值值變化，進而達到構型優化之目的。
透過使用Captive-model的實驗設計以及經過簡化處理的六自由度運動方程式加以空間軌跡預測而獲得傳統潛艇操作性能的評估。實驗方式包括有利用推曳水槽之阻力與自推點試驗、利用PMM與RAT獲得攻角、偏角、等(角)加速度以及控制面舵角等不同操控姿態下的水動力係數與導數資料庫。

For the optimization of the submarine's operability, in addition on making changes in large areas such as the hull and sail, through the changes in small areas, the effect of achieving performance optimization is relatively more in line with actual needs. In the
configuration, the flow field and numerical value changes of the X rudder and the cross rudder under the interaction of the hull-tail rudder-propeller are compared, and the purpose of slenderness is to optimize the configuration.
The evaluation of the operational performance of traditional submarines is obtained through the experimental design using Captive-model and the six-degree-of-freedom motion equations inserted into the space trajectory prediction through simplified processing. RAT obtains a database of hydrodynamic coefficients and derivatives under different pointing attitudes such as angle of attack, declination, equal (angular) acceleration, and control surface rudder angle.
