Aerodynamic drag
原声例句
CNN 10 学生英语 2023年2月合集 Today, hyperloop technology is based on two key mechanisms, removing aerodynamic drag through vacuum-like tubes and removing friction through magnetic levitation or maglev, which makes the pods float and move forward. 如今，超级高铁技术基于两个关键机制，通过真空管消除空气阻力，通过磁悬浮消除摩擦，这使得乘客舱漂浮并向前移动。 TED-Ed（视频版） Adjusting the wing sweep, or the angle at which wings protrude from the fuselage, to bring the wings closer in can make an aircraft faster by reducing aerodynamic drag. 调整机翼后掠角，或机翼从机身突出的角度，使机翼靠得更近，可以通过减少空气阻力使飞机更快。
