【摘要】 本文将对五个展弦比的转柱舵进行试验分析,求得转柱舵水动力系数随展弦比、速度比变化的一般规律,并且将转柱舵的升力、阻力系数和压力中心无因次系数随展弦比、速度比、舵角的变化绘成系列图谱,提出了获得较优转柱舵水动力性能的展弦比、速度比选择区限。另外,本文将给出一定舵角范围内升力、阻力系数的二元非线性多项式计算公式。更多还原

【Abstract】 Empirical formulae are presented in this paper for the calculation of non-dimensional hydrodynamic coefficients as function of aspect ratio of rotating-cylinder rudder (RCR), speed ratio and rudder angle, based upon the results obtained from a series of model experiments. Optimization in the disign of RCR will be possible.更多还原
