A method of securing an workpiece for machining the trailing edge. The workpiece has a platform from which extends an airfoil, the airfoil including a leading edge and a trailing edge, and a pressure side and a suction side. A fixture with at least one locating datum that relates to the platform and at least one locating datum that relates to the leading edge is provided. The fixture does not contact the trailing edge of the workpiece. The workpiece is positioned so that the platform is against the related locating datum and the leading edge is against the related locating datum. The workpiece is secured within the fixture, and the trailing edge of the workpiece is machined.

Trailing edge machining of a workpiece

A method of processing turbine airfoils includes depositing a protective coating on first and second turbine airfoils, and bonding the first and second turbine airfoils together after the deposition such that there is an open throat between the first and second turbine airfoil and at least portions of surfaces in the open throat are coated with the protective coating.

Method and assembly for gas turbine engine airfoils with protective coating

Systems and methods for performing cooling airflow analysis of gas turbine engine components are provided. In this regard, a representative system includes an airflow insert operative to form a seal with a component, the airflow insert having a main portion and a removable sacrificial portion, the sacrificial portion being sized and shaped to engage the component, the main portion having a cavity sized and shaped to removably receive the sacrificial portion, the main portion being sized and shaped to form a seal about the sacrificial portion and a corresponding portion of the component.
