摘要
舵合理布置于船尾螺旋桨后方能有效吸收螺旋桨尾流,达到船舶操纵性能优化设计的目的.根据螺旋桨尾流特征,设计了舵的4个横向和3个纵向,共计6个舵布置位置方案,通过自由自航模型试验考察舵布置位置对操纵性的影响.在湖上开展了船模回转、Z形操舵和回舵试验,速降和静横倾角的试验结果符合一般操纵性规律,表明试验结果的有效性.
The rudder is always placed behind the propeller to absorb the energy in the wake flow, thus to achieve a more optimized maneuverability. According to the characteristics of the propeller flow, six kinds of rudder arrangement were adopted by varying the lateral and longitudinal distances away from the propeller. In each case, the free-running model test was carried out in the lake, including the turning circle test, the zigzag test and the pull-out test. The speed drop and the static roll angle agree well with the general rules of maneuverability. By testing the parameters and analyzing the test data, different effects on the turning ability, the course-keeping ability, and the response to intermediate and small helm angles were achieved with different rudder arrangements.
