潜艇操纵面几何参数敏感性计算研究

以潜艇垂直面操纵运动线性运动方程为基础,以反映潜艇垂直面操纵性特征的典型技术指标为评价体系,提出了潜艇操纵面几何参数敏感性概念,采用敏感性指数作为评估操纵面参数对潜艇垂直面操纵性影响的指标.在主艇体参数固定条件下,为潜艇设计了系列参数的首尾操纵面,采用Bohlman的水动力估算方法,估算了该艇的线性水动力系数.在水动力估算和敏感性概念的基础上,开展了大量的敏感性计算,分析计算结果得到了潜艇首尾操纵面几何参数不影响潜艇逆速,尾操纵面对首舵升速率有很强影响等结论.

A calculation and study on sensitivity of geometrical parameters of control surfaces for submarines

Based on the linear maneuverability equation,choose the typical characters of a submarine maneuvering in vertical plane as the evaluating system,bring out a new concept of sensitivity of the geometrical parameters of control surfaces,and evaluated the affect of maneuverability by control surfaces' parameters by using the sensitivity index.Designed a series of control surfaces on the condition of the fixed parameters of the main bodies of the submarine,estimated the hydrodynamic coefficients by using the Boh...
