针对被动翼复合船型,采用模型试验方法,开展阻力和耐波性模型试验,分析一对首水翼和一型T型翼对阻力和垂向运动的综合影响。试验结果表明,加装被动翼之后,中低速时静水阻力增幅较大,高速时静水阻力增幅减缓;在1倍波长船长比附近,纵摇、垂荡、首尾垂向加速度大幅减小;波浪增阻显著降低。综合而言,被动翼复合船型在风浪中航行时,快速性与原船型相当,耐波性大幅提升,对改善船员舒适性和船上设备使用环境具有有益效果。
Based on the model experiment, researched on the resistance and seakeeping performances of hybrid monohull combined with passive foil. Then the compositive effects on resistance and vertical motions induced by a pair of fore foils or a type of T-foil were analyzed. The experiment results indicated that when fixed passive foil,the resistance in calm water increased a lot at mid or low speeds and amplification decreased at high speeds. When wave length-ship length ratio approximated one, the vertical motions decreased greatly and added resistance in waves also decreased significantly. In a word, when hybrid monohull combined with passive foil sails in waves, the resistance changes a little. At the same time, the seakeeping performance improves a lot. So the hybrid monohull combined with passive foil have benefits to comfort and operating environments of shipboard equipments.
