乌江中上游双尾与隧道尾结合的机动驳船型

Self-propelled Barge with Tunnel Twin-skeg Stern

本文通过对隧道尾、涡尾及隧道尾与双尾结合尾型等三种船型的船模快速性试验结果分析，得出隧道尾与双尾结合船型是浅水急流机动驳较适宜的船型，其单位功率负载率和海军系数较现有优秀隧道尾船型分别提高28．61％和34．31％。

The model test results of three ship forms,namely the tunnel stern,the cochlea stern and the tunnel twin-skeg stern, demonstrate that the ship with the tunnel twin-skeg stern is more appropriate for navigating in the shallow water and the rapid current,as in the middle and upper reaches of Wujiang. In comparison with the existing excellent ship with the tunnel stern,the Admiralty coefficient and the load efficiency per power of the self-propelled barge with the tunnel twin-skeg stern increased by 28.6% and 34.3% respectively.
