Article having a design external aerodynamic shape and method for making the same

摘要

An article (30) having a design external aerodynamic shape includes a body (32) with a body external surface (34) and an outer portion external surface (38) of an outer portion (36) bonded with a part (14, 16) of but less than substantially all (12, 14, 16, 18) of the body surface. The external surfaces (34, 38) of the body (32) and outer portion (36) each define less than the design external aerodynamic shape. However, together they define such shape. The article (30) is made by selecting the design external aerodynamic shape from an existing article (10) having a first body (20) and a first outer portion (24). A replacement outer portion (36) is selected in an amount less than the first outer portion (24) and bonded with a region (14, 16) less than substantially all (12, 14, 16, 18) of a replacement body external surface (34). The replacement body (32) has a replacement body external surface (34) and replacement body external shape (34) different from the first body (20) substantially by that amount. The replacement body (32) is made with the replacement body external shape (34). Then the replacement outer portion (36) is bonded with the region (14, 16) of the replacement body external surface (34). The result is that the external surfaces (34, 38) of the replacement body (32) and replacement outer portion (36) together define the design external aerodynamic shape.
