摘要 论述了螺旋桨负荷系数对潜艇操纵运动的影响 .通过分析试验数据 ,获得了螺旋桨负荷系数对潜艇水动力的改进数学模型 .应用这一数学模型 ,对潜艇在螺旋桨变负荷情况下的大机动运动特性进行了分析 。 The influence of propeller loading coefficient on submarine maneuvering motion was studied. By analyzing testing data, an improved mathematical model of propeller loading coefficient of submarine hydrodynamics was presented. This model comprehensively expressed the non-linear hydrodynamic forces induced by the propeller loading coefficient coupled with attack angle, drift angle, pitching velocity, stern plane angle etc., and the hydrodynamic characteristics of submarines working in special motions or large attack angles were considered. The normal six-freedom submarine motion equations were improved. This model was used to analyze the motion behavior of a submarine with its propeller loading coefficients changed. It was proved that the propeller loading coefficient has a trivial influence on normal space spiral motion and tuning circle, but will have a remarkable influence on such motions as locking stern plane angle or cabin entering water etc. This model can help to obtain good results of forecasting submarine maneuvering motion.
