阻尼导数 meaning in English
damping derivative
Examples
- The damping derivatives can only be determined experimentally in the wind tunnel or ballistic range .
阻尼导数只能用风洞或弹道试验来确定。 - The aerodynamic characteristics of a projectile with wrap around fins are studied systematically in this paper , as follows : 1 . the lift coefficients 、 drag force coefficients 、 pitch moment coefficients 、 pitch damping moment derivatives and roll damping moment derivatives are obtained from engineering calculation through looking wrap around fins as flat fins of the same projection aera
