翼型

And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.

运用翼型的基本概念和风力机叶片的基础外型参数进行叶片设计的预研讨论，并分别运用了Glauert和Schmitz叶片设计方法叶片进行初步设计，这两种方法有其各自技术特点和缺点，文中还着重研究了动量—叶素理论方法，这种方法在前两种设计方法的基础上发展而成，并采用两者的叶素研究方法进行叶片设计，动量叶素理论方法在进行叶片外型设计和叶片气动特性计算都涉及到干涉因子，文中重点对设计和计算情况下的干涉因子进行处理，并由此来设计叶片的外型和进行气动特性的计算。

Loss of head is minimized by the balanced disc and its "aerofoil" design.

Birds have the advantage here: since the feathers can overlap to differing degrees, birds' wings can maintain an effective aerofoil over a greater range of shape changes.

鸟类有其优点，在这里：由于羽毛可以重叠，在不同程度上，鸟类的翅膀，可以保持一个有效的翼型超过了更广泛的形状变化。
