气动阻力 meaning in English

aerodynamic drag force
aerodynamic resistance
aerodynamical drag
aerodynamical resistance

An experimental study on the square - formed fences used for reducing the drag on steyr van truck
厢式货车减小气动阻力的实验研究
The flight test of ec155 tells us that inter - blade dampers can work very well in stabilizing the system ; another advantage of this configuration is it can make the hub system simpler and reduce the drag of air to the hub which is very important for helicopters with 4 or more than 4 blades
Ec155的飞行试验证明,这种减摆器布置方式对提高稳定性效果明显;这种布置方式的另外一个优点是可以简化桨毂,降低其气动阻力,对多桨叶(四片和四片以上)直升机有重要意义。
