1·The blades have an aerofoil shape and provide lift when passing through air, like the wings of an aeroplane.
这些叶片拥有机翼的剖面形状，它们就像普通飞机的机翼那样，通过划过空气来产生升力。
2·The serpentine aerofoil shape is designed to face into what little wind there is, generating a small amount of lift.
蛇形蜷曲的机翼设计用来面对空中的较小风力去产生一个较小的升力。
3·The aerofoil of a wing creates more lift than drag, but exactly how much depends on its design and the speed of the air passing over it.
飞机上的机翼制造升力超过阻力，但具体取决于机翼的设计和当时经过的空气流动速率。
4·With use of this structure model, we can simulate the real performance of aerofoil very well.
应用该结构模型可以很好的模拟机翼结构的实际情况。
5·A good mechanics analysis approach was presented for reliability analysis and damage tolerance design of aerofoil structure.
为机翼结构的可靠性分析和损伤容限设计提供了比较有价值的力学分析手段。
