摘要
对LPC快艇加装声呐球鼻艏船进行模型阻力试验,设计了适合此快艇加装声呐球鼻艏的5种方案。试验得到5种方案的19种状态的船模试验基本参数,在换算成实船后得到实船总阻力曲线图、实船有效功率曲线图和实船剩余阻力曲线图。船模阻力试验结果表明,加装此5种球鼻后,船模总阻力增加都较小,且在设计航速上仍有较好的耐波性和稳定性,综合船舶快速性与耐波性,选定了适合此型快艇的球鼻方案。
Series of resistance tests were carried out for large patrol boats with bulbous bow. Five kinds of solutions of bulbous bow including 19 situations were made to get experimental data of resistance. Based on the experiments data, actual ship resistance curve, effective power curve and residual resistance curve were made. Then some professionals were organized to analyze on the experimental results, especially discussed on hull total design, the overall performance and conditions needed on added bulbous bow. According to ship total resistance, ship sea-keeping, ship stability and ship quickness, the optimum design from five bulbous how was selected which has the minimum resistance effects and can increase the stability of the ship.
