翼型
機翼或葉片的曲面，飛行時產生升力
a specially shaped surface, such as that of an aircraft wing or a fan blade, built so that air moving across it pushes the object upward or helps keep it steady during flight
Engineers tested the airfoil design in a wind tunnel before fitting it to the prototype.
工程師在風洞中測試翼型設計，然後才安裝到原型機上。
collocation: airfoil design, tested in a wind tunnel
A helicopter blade uses the airfoil principle to generate lift, just like an aeroplane wing.
直升機的葉片使用翼型原理來產生升力，就跟飛機機翼一樣。
the airfoil principle
An airfoil's curve makes air above flow faster than air below, creating lift.
翼型的彎曲使上方氣流比下方氣流更快，產生升力。
Modern wind turbines use shaped airfoils on their blades to capture energy from the wind.
現代風力發電機在葉片上使用翼型設計，從風中擷取能量。
Dr. Okafor showed how changing an airfoil's curve affects its performance at different speeds.
Okafor 博士展示了改變翼型彎曲度如何在不同速度下影響其性能表現。
用法筆記
In British English the preferred spelling is aerofoil. The shape works the same way whether used on an aircraft wing, a propeller blade, or a wind-turbine blade.
