Abstract: The present disclosure is directed to a system and method for in-situ (e.g. on-wing) cleaning of gas turbine engine components. The method includes injecting a dry cleaning medium into the gas turbine engine at one or more locations. The dry cleaning medium includes a plurality of abrasive microparticles. Thus, the method also includes circulating the dry cleaning medium through at least a portion of the gas turbine engine such that the abrasive microparticles abrade a surface of the one or more components so as to clean the surface.

Abstract: A method of forming a hole in an engine component. The hole is formed through a wall defining first and second opposing surfaces. An inlet is located on the first surface and an outlet on the second surface where a passage connects the inlet and the outlet. Fluid is passed through the passage, emitted from the passage, and redirected upon existing the outlet.
