对转桨推进型鱼雷有动力影响研究

Power effect research on torpedo model with counter-rotation pusher propeller

为使国内具备鱼雷有动力风洞试验能力 ,通过设备研制和对转桨推进型鱼雷性能研究试验表明 :一是动力对姿态导数影响达 40 % ,效率导数一般下降 1 0 %～ 1 5 % ,设计单位应重视上述特性对鱼雷航行与机动特性的影响 ;二是对转桨对雷体稳定性作用值得高度重视 ,传统认为对转桨是鱼雷辅助稳定装置的设计思想应有所调整 ,尤其对机动性要求高的鱼雷。

For study the power effect on counter-rotation propeller torpedo,CARDC developed the research on wind tunnel test technique of torpedo with CSSC. This paper introduces the process of setting up the base for the wind tunnel test of torpedo, and the test facility for the test of torpedo model with power system. Through the test of counter-rotation propeller torpedo, examined the test facility, gave out the research result,test precision,model support system interference effect, and also verified the torpedo characteristic research ability with power in the low speed wind tunnel.Research shows: Power effect on the derivatives related with model attitude takes about 40%,and reduce the derivatives related with efficiency about 10%～15%.What must be put special attention to design is these behaviour may have some effects on the ability of torpedo navigation and mobility. Furthermore, the contribution of counter-rotation propeller to torpedo stability is considerable enough to be worth noticing. The design idea that counter-rotation propeller is a supplement stability device of torpedo must also be adjusted.
