被动翼复合船型航行性能模型试验研究

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。

Research on the experiment of navigation performance for hybrid monohull combined with passive foil

Based on the model experiment, researched on the resistance and seakeeping performances of hybridmono-hull 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 foilthe 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 andop-erating environments of shipboard equipments.
