| 摘 要： | 长江中下游顶推船队采用襟翼舵+导管桨+倒车舵的联合推进-操纵系统,这种特殊的推进-操纵装置在国内研究甚少,国外发表的可供新船队设计应用的资料也很少。 本文根据新设计的由三种推轮和两种驳船组成的七种船队的大量自航模操纵性试验结果,探讨了舵面积、舵型、推轮、编队等因素对船队操纵性的影响,为设计新船队提供了必要的依据。本文还参照Lyster-Knights的双桨船的回转直径估算公式,考虑了推轮的影响,给出了适合于估算同类型推轮船队回转直径的近似公式。

| Abstract: | A special propulsion and manoeuvring device composed of flapped rudders, ducted propeller and flanking rudders is used for the push train in mid and down stream part of Yangtze River. The systematic study on this kind of device at stern of push train is little in China, and published information abroad about the same is also scarce.Based upon the manoeuvring test results of seven self running model combined with three new designed pushers and two barges, the effect of rudder types, rudder area and the push train with different configurations on the manoeuvrability have been investigated. The information for push train design acquiring from the investigation is presensed. Finally, by consulting the Lyster and Knights formula for prediction of turning circle of twin-propeller ships, an approximate formula to estimate turning circle elements for push train of similar type is included. |
