Through the analysis and computing, it can be found tLhat the restoring moment in waves shows obviousnonlineallty as the roll angle is bigger.
通过对实例的分析与计算，得到波浪中船舶横摇稳性的特性，同时亦看到船舶在波浪中的横摇恢复力矩在大角度横摇时表现出明显的非线性。
Aimed at the vee tail of an UCAV,the longitudinal moments of up vee tail and down vee tail are calculated by the method of solving N-S equations.
针对某无人战斗机所采用的V形尾翼布局,通过求解N-S方程的数值计算方法,得到了上反与下反V形尾翼气动布局的纵向力矩值。
