Integrated compressor vane casing

摘要

A low leakage, integral fixed vane system for a gas turbine engine compression system which can accommodate the latest 3-D aerodynamic airfoil geometries and provide endwall ovalization control. A unitized construction wherein the vanes are integral with the case wall in the compression system.

1. A method of forming a gas turbine engine component,
the method comprising: casting, as a single article, a circular shaped vane casing segment of a gas turbine engine case having an outer case wall, a plurality of airfoils extending from a lower surface of said outer case wall, and an inner shroud extending from a lower portion of said plurality of airfoils; plasma spraying an abradable surface on a lower surface of an extension of the outer case wall; and forming a feed through aperture and cavity in the outer case wall concurrent with the casting as a single article.
