大侧斜对转螺旋桨在鱼雷上的应用研究

文章从鱼雷螺旋桨设计过程中的噪声性能分析和强度分析两个方面研究了大侧斜对转螺旋桨应用于鱼雷的设计方法,并通过一个具体的鱼雷大侧斜螺旋桨设计实例和试验验证来说明此设计方法在鱼雷大侧斜螺旋桨设计中的应用前景及设计过程中的改进措施.研究结果表明,采用大侧斜桨叶可以得到良好的推进性能和更好的空泡噪声性能,而且振动小.同时也指出了大侧斜螺旋桨所存在的不足.文章对鱼雷用螺旋桨的设计和实际应用具有参考价值.

Application of high-skewed contrarotating propeller for the torpedoes

The design methods of the high-skewed contrarotating propeller used for torpedoes in terms of the noise character and strength character were described. An example and a test are presented. The result shows that both the propulsive efficiency and maneuver capability are improved,and shock is absorbed. There is no cavity in high speed. The defects of the propeller are also presented.
