| 摘 要： | 在高速拖曳水池里,开展了气泡高速艇规则波中阻力及纵向运动模型试验,研究了气流量、艇型、艇底开槽等因素对气层减阻率及艇体纵向运动性能的影响。结果表明:艇底形式对波浪中的气层减阻率有重要影响。艇底设置断阶时,在短波中减阻率为5%,长波中的减阻率达20.5%;艇底开槽时,在试验波长范围内,减阻率可达30%左右;对本身具有良好喷溅抑制作用的艇型,艇底直接喷气减阻率为8%,且不受波长变化的影响。艇底气层对纵向运动性能影响较小,长波中还略有改善;艇底槽深主要影响不喷气时的阻力,对饱和喷气下的阻力影响甚微。

| Abstract: | In order to study the resistance and longitudinal motion of high speed air cavity craft model in regular waves, an experimental investigation was carried out in high speed towing tank. The effects of factors such as air flow rate, hull form and hollow bottom on the resistance reduction rate and longitudinal motion performances were studied. The following findings were obtained: the resistance reduction rate by air injection from the bottom surface of a craft in regular waves was closely related to bottom hu... |
