Abstract
Official abstract text for this publication.
A method of servicing an airfoil for use in a gas turbine engine. The airfoil assembly is defined by a base material and includes an airfoil and a platform from which the airfoil extends. A predetermined amount of the base material is removed from the airfoil assembly proximate to a fillet area of the airfoil assembly via water jet material removal. The fillet area comprises a junction between the airfoil and the platform and is located at an intersection between the airfoil and the platform. A remainder of the base material comprising base material of the airfoil assembly other than proximate to the fillet area is left intact.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of servicing an airfoil assembly for use in a gas turbine engine, the airfoil assembly defined by a base material and comprising an airfoil having a radially inner end which is attached to a platform from which the airfoil extends, the method comprising: removing predetermined amounts of the base material from the airfoil assembly proximate to a fillet area and the radially inner end of the airfoil assembly at leading and trailing edges of the airfo…
