aerodynamic forces of train的用法和样例：
- The linear aerodynamic forces of airship hull were calculated in terms of Munk airship theory. The linear aerodynamic forces of airship hull were calculated by Allen viscous cross flow theory.
- The present method can be used to calculate the aerodynamic forces of a circulation control airfoil performing translating and pitching oscillation with moderating amplitude and frequency.
本文 的方法可以计算控制环量翼型以适当振幅和频率作平移和俯仰振荡时 的气动力。
- Wind fences can reduce aerodynamic force of railway vehicle in the cross-winds,and the performances of wind fences might be affected by many factors.
- Through calculation of unsteady flow field of stator-rotor model, the spectrum and amplitude of unsteady aerodynamic force of two mistuned design packages were compared.
