The manoeuvrability of a cable laying vessel fitted with Kort nozzle rudder is discussed by using the method of model test.Test comparisons were made between Kort nozzle and a normal rudder, simultaneously,model tests were carried out on skegs behind Kort nozzle with three different area and also on deadwood in three different cut conditions.From analysis the following conclusions can be made:(1)The turning ability of a vessel fitted with Kort nozzle rudder is better than that of a nor- mal rudder,particularly when going astern.(2)The change of area of skeg has no serious effect upon turning ability of a ship.(3)Under the same rudder angle,the speed loss in turning of Kort nozzle is greater than that of a normal rudder,however under the same nondimensional angular speed,both speed losses are same.(4)After cut of deadwood,the relative turning radius of a ship reduces greatly,and it is more significant in small rudder angle,however the course stability becomes worse.

本文用模型试验方法讨论了装有回转导管工作船的操纵性。对装有回转导管及装有舵的船舶进行了比较试验,同时也对三种不同面积的平衡叶及三种尾呆木切割状态进行了模型试验。通过分折可以得出如下结论:1.装有回转导管的工作船的回转性能比装有舵时为好,倒航时尤为显著。2.变化装于回转导管后面的平衡叶面积,对船舶回转性能无显著影响。3.在相同舵角下,装有回转导管的船舶在稳定回转时的速降大于装有舵时的速降,但在同一无因次角速度下,两者速降一致。4.呆木割除后,船的相对回转直径显著减小,小舵角时更为明显,但航向稳定性随之变差。
