| 摘 要： | 对蜗尾型双桨推轮首次进行了线型研究和模型试验研究,给出了一种与常规蜗尾有很大差别、与正车舵+导管桨+倒车舵系统有良好匹配性能的新的蜗尾型推轮.推轮+驳队的模型阻力和自航试验表明,这种新的蜗尾型推轮具有优良的推进性能.径深比D/T=1.0的蜗尾型推轮的推进效率Q.P.C可达0.5以上,比相同径深比的常规隧道尾型推轮高25%以上.蜗尾型推轮是一种有很好的应用和发展前景的新型内河推轮.

| Abstract: | The lines research and model test results of a new cochlea-channeled-stern pushboat with twin screws are presented. The new pushboat proposed is very much different from that with a conventional cochlea-channeled-stern and it is fitted with forward rudders + ducted propellers + backing rudders system. Model test results of the new pushboat with barges show that the propulsive performance is excellent. The Q. P. C of the boat with a diameter/ draught ratio D/T=1. 0 exceeds 0. 5 and it is 25% or even higher than that of conventional tunnel-stern pushboats with the same D/T. |
