干扰阻力

本文分析了几艘实用双体船的模型试验资料并以图表的形式表达了双体干扰阻力分数Kr与间距比K/b、付汝德数Fn和棱形系数CP的关系；

This paper analyses the model test results of some conventional catamarans , and gives graphically the relationship between interference resistance fraction K_r and separation ratioK / b ;

双体船的兴波阻力系由自身兴波阻力和干扰阻力两部分所组成，主要是船型形状、佛氏数和间距船长比的函数。

It is then derived that the resistance of catamarans should be the functions of ship form , Froude number and separation-length ratio .

试验研究了外挂干扰引起的阻力系数的变化，特别是外挂吊挂方式、外挂位置变化引起的阻力变化以及多外挂间的干扰系数。

In this paper , investigations are conducted with experiments in wind tunnels for the Changes of drag Coefficient on the store induced by interference between aircraft and stores , especially interference of store suspension forms , store positions and multiple stores .
