| 摘 要： | 对影响吊舱推进器螺旋桨性能的因素进行了分析,提出应用常规螺旋桨图谱估算POD桨敞水特性曲线的方法,根据已知POD桨的敞水特性资料,通过保持盘面比不变改变螺距比迭代计算得到等效常规螺旋桨,根据得到的螺距比变化规律和常规桨图谱,设计POD桨和估算其敞水特性,并给出算例。

| Abstract: | The influence factors such as the hub,strut and the gap between the pod and propeller are analyzed.A method to modify the basic POD propeller efficiency curve to a new POD propeller efficiency curve is proposed,in which the area ratio is kept fixed,changing the pitch ratio to find the equivalent propeller.By the variety rule of the pitch ratio and the conventional propeller chart,a POD propeller is designed and its open water characteristics are calculated.Some numerical results are given. |
