摘要
本文应用回归分析和相关分析的理论对测试螺旋桨推力减额分数的船模试验结果进行了分析研究,提出了以进速系数(Js=Vs/nD)为参数计算推力减额分数t值的公式。该公式对研究在变加速情况下的船舶操纵运动有一定的参考价值。
By the use of the theories of Regression Analysis and Relation Analysis, a new formula of the advance number of ship (J_s=V_s/nD) as a function, which calculates the thrust deduction factor (t),is proposed based on analysing the model experimental results of testing propeller thrust deduction factor. this formula provides valuable reference for studying the manoeuvring motions of a ship under varying accelerated motion.
