The objective of the proposed work is to advance the understanding of the physical phenomena involved in the loading of azimuthing podded propellers. Additional knowledge concerning propeller hydrodynamics is the foundation for safe and innovative applications of this novel marine propulsor. The approach combines experimental and numerical elements, both building upon the previous work of the applicant. In brief, the work will consist of examining the hydrodynamic loads on podded propulsors in oblique flow and dynamic azimuthing conditions based on a focused experimental investigation in open water and under cavitating conditions. The experimental work will include an investigation of the interaction effects of dual propellers. A model will be developed to predict hydrodynamic loads on propellers during unconventional operations. An existing panel method code will be extended and validated for podded propulsor performance prediction. The numerical code will complement and extend the knowledge derived from the experimental program, and will be used to predict propeller performance, particularly for conditions that are not amenable to experimental investigations.

拟议工作的目的是增进对全向吊舱螺旋桨加载所涉及的物理现象的理解。有关螺旋桨流体动力学的附加知识是这种新型船用推进器的安全和创新应用的基础。 该方法结合了实验和数值元素，两者都建立在申请人之前的工作的基础上。简而言之，这项工作将包括基于开放水域和空化条件下的集中实验研究，检查斜流和动态方位角条件下吊舱推进器上的水动力载荷。实验工作将包括双螺旋桨相互作用效应的研究。将开发一个模型来预测非常规操作期间螺旋桨上的水动力载荷。现有的面板方法代码将得到扩展和验证，以用于吊舱推进器性能预测。数字代码将补充和扩展从实验程序中获得的知识，并将用于预测螺旋桨性能，特别是在不适合实验研究的条件下。
