| 摘 要： | 高速滑行艇处于滑行状态时的阻力性能一直是滑行艇水动力性能研究的重点和难点。首先采用半经验半理论的Savitsky法对棱柱形滑行艇的航行姿态与阻力进行研究分析,计算纵倾结果与试验结果吻合良好。然后改变滑行艇的长宽比、重心纵向位置与底部斜升角参数,进一步研究三种参数变化对滑行艇航行姿态与阻力性能的影响。研究结果表明:基于半经验半理论的Savitsky方法可用于棱柱形滑行艇的阻力性能分析;在高速阶段,长宽比、重心纵向位置与底部斜升角参数对阻力影响较大。

| Abstract: | It''s difficult to study the hydrodynamic performance of high-speed craft during its planing. Based on the semi-empirical Savitsky''s method, the navigation attitude and resistance of a prismatic planing hull are studied and analyzed, and the calculated results of trim are in good agreement with the experimental ones. Then the influence on the resistance performance of the planing hull are further investigated in various aspects including ratios, longitudinal positions of the center of gravity and the deadrise angles. The results show that the semi-empirical Savitsky''s method can be used to analyze the resistance performance of prismatic planing hull. |
