摘要
对吊舱式推进装置进行了多方案的模型试验研究 ,考察了串列式吊舱推进装置前后桨的负荷匹配及初始相位角的影响 .空泡水筒敞水试验结果表明 ,无论双桨串列式或单桨拖、推式吊舱推进装置 ,由于吊舱影响使螺旋桨效率均比常规桨有所提高 ;但若计及吊舱阻力则吊舱推进装置的系统效率有所下降 .可以预见 ,吊舱式推进装置因其众多的优越性而具有广阔的发展前景 .
A series of tests were carried out for towing, pushing, and tandem type podded propulsors in a cavitation tunnel. The experimental results indicate an increase in propeller efficiency as compared with the case of a propeller without pod. Although the resistance of pod plays a negative role, considering the various merits of podded propulsors, it can be expected that this new type of propulsor will be widely developed in the near future.
