Abstract
Official abstract text for this publication.
A blade outer air seal for a gas turbine engine having a surface that is eccentric with respect to the engine rotation centerline, and a method for creating same, are disclosed. Also, a method for grinding a work piece having nominal curvature defined by a work piece curvature centerline is disclosed, comprising the steps of: a) determining a desired surface profile for the work piece; b) providing a rotating grinding surface having a grinding rotation centerline; c) offsetting the grinding rotation centerline from the work piece curvature centerline; and d) applying the rotating grinding surface to the work piece while rotating the rotating grinding surface about the grinding rotation centerline to create the desired surface profile.
First claim
Opening claim text (preview).
What is claimed: 1. A blade outer air seal for a gas turbine engine having an engine rotation centerline, comprising: a substrate having a first end and a second end, wherein a blade within the engine rotates past the first end and then past the second end when the engine is running; and a coating applied to the substrate; wherein the substrate and the coating define a first combined thickness at the first end and a second combined thickness at the second end; wherein the firs…
