摘要
为了验证三体滑行艇超高速航行能力,研究其阻力特征和船型特点,通过船模试验测量了不同排水量、重心位置下的阻力、纵倾角和升沉,研究了压浪条对阻力与航态的影响.试验结果表明:三体滑行艇2个辅助片体的存在加大了高速航行时气动升力的影响,改善了其水动力性能,具有优异的纵向稳定性和极小的兴波与喷溅,在Fr>8条件下仍能稳定航行,航行过程中出现2次明显的阻力峰和航态变化,第2次航态变化幅度小于第1次,压浪条对高速航行时的航态有一定的改善作用.
To verify the ability of a trimaran-planing boat sailing at ultra-high speeds and to investigate its characteristics of resistance,model tests were conducted to analyze the resistance trim,heave and effeets of spray rails of models with different displacements and center of gravity locations.The results show that the two outriggers of the trimaran-planing boat increase the impact of aerodynamic lift and improve the hydrodynamic performance at high speeds,leading to excellent longitudinal stability,low resistance,and less spray.With the Fr8 conditions stable sailing was still possible,and there were two significant changes in the resistance peak and altitude.Also,the second amplitude was lower than the first,and the spray rails improved the boat altitude at very high speeds.
