Abstract: A method of fabricating an airfoil includes the steps of fabricating a first core including a first plurality of ribs defining a first plurality of passages of a completed airfoil, and fabricating as second core including a second plurality of ribs defining a second plurality of passages of the completed airfoil. The second plurality of ribs includes a plurality of standoffs. The plurality of standoffs set a spacing between the first plurality of ribs and the second plurality of ribs to define a spacing between the first plurality of channels and the second plurality of channels of the completed airfoil. The airfoil is then molded about the core assembly. Once completed, the core assembly is removed to provide a completed airfoil incorporating multiple microcircuits with a desired stability and structural integrity.

Abstract translation: 一种制造翼型的方法包括以下步骤：制造第一芯，其包括限定完成的翼型件的第一多个通道的第一多个肋，并且制造为第二芯，该第二芯包括限定第二多个通路的第二多个肋 完成机翼。 第二多个肋包括多个支座。 所述多个支座在所述第一多个肋与所述第二多个肋之间设置间隔，以限定所述第一多个通道与所述完整翼型的所述第二多个通道之间的间隔。 然后将翼型件围绕芯组件成型。 一旦完成，移除芯组件以提供具有期望的稳定性和结构完整性的并入多个微电路的完整翼型件。
