摘要:
A method for fabricating an airfoil includes forming a diffuser section in an exterior surface of the airfoil. The diffuser section is defined by at least an outer surface and an inner surface that converge at a stop surface. The method also includes positioning a drilling element of a drilling device on the stop surface. The method further includes orienting the drilling element at a first angle relative to the exterior surface. The method also includes forming, using the drilling element, a cooling channel extending through the airfoil from the stop surface to an interior surface, thereby forming the cooling channel at substantially the first angle.
摘要(中):
一种用于制造翼型的方法包括在翼型件的外表面中形成扩散器部分。 扩散器部分由至少外表面和在止动表面处会聚的内表面限定。 该方法还包括将钻井装置的钻孔元件定位在止动表面上。 该方法还包括相对于外表面以第一角度定向钻孔元件。 该方法还包括使用钻孔元件形成从止动表面延伸穿过翼型件到内表面的冷却通道,从而以大致第一角度形成冷却通道。
