Trailing edge thickness measurement method and apparatus |
摘要 |
Apparatus for measuring the trailing edge thickness of an airfoil in a turbine includes a plurality of tools; each tool having a main body portion and a forward end; an opening along a side edge and in proximity to a forward edge of the forward end, the opening including a slot of predetermined width adapted to engage the trailing edge of the airfoil; wherein each of the tools has a different predetermined slot width. A method for determining the trailing edge thickness of an airfoil in a turbine includes the steps of: a) providing a tool having an opening including a slot having a predetermined width, the opening adapted to receive the trailing edge of the airfoil; b) aligning the tool to receive the trailing edge of the airfoil in the opening; c) determining if a match exists between the trailing edge and the slot width; d) if no match, repeating steps a) through c) with a tool having a different predetermined slot width until a match is found; and e) recording the size of the tool, as identified by the predetermined slot width, as the actual trailing edge thickness of the airfoil.
