摘要
对一艘船艇作了波浪中自航试验研究,得到了规则波中自航因子变化曲线,用直接功率法作了失速预报,并用谱分析法预报了该艇的纵摇、升沉及螺旋桨出水概率。本文的重要结论:船艇在波浪中的自航因子在简化处理时,可以认为相当于静水中的自航因子。
The self-propulsion tests of a boat in waves were researched. The curves of self-propulsion factor variation in regular waves were obtained, the speed loss was predicted with direct powering method, the pitching, heaving and the probability of propeller out of water also predicted with spectrum analysis method. The important conclusion of this paper is that the self-propulsion factors of boat in waves are equal to that in calm water when they are daelt simply.
