| 摘 要： | 在高速拖曳水池里开展了B.H.型气泡高速艇静水阻力及规则波纵向运动模型试验,研究了气流量、航速、波长、波高等因素变化对B.H.艇波浪中阻力、垂荡、纵摇、垂向运动加速度的影响。探讨了波高变化对饱和气流量的影响。研究结果表明:静水中B.H.艇相对减阻率可达36.25%,绝对减阻率可达20.79%,迎浪规则波中相对减阻率可达32.3%,与静水减阻效果基本相当,波长变化对减阻率的影响甚微。气层并未导致纵向运动性能的恶化,相反在一定航速与波长范围内,艇底气层能改善垂荡与纵摇运动;饱和气流量下,阻力、垂荡、纵摇及重心垂向运动加速度随波高呈非线性变化,航速增大非线性增强,波长增加非线性降低;波浪中饱和气流量随波高呈非线性变化。

| Abstract: | The performances of bottom hollowed high speed air cavity craft in still water and regular wave are experimentally investigated in high speed towing tank.The effects of some parameters,such as air flow rate,hull speed,wave length and wave height ect.on the resistance of high speed air cavity craft and its longitudinal motion performances are investigated,and the effect of wave height on saturated air flow rate is discussed.Some results can be taken as follows: The relative resistance reduction rate is about... |
