1. A method for forming an impingement sleeve, the method comprising:
- designing a cooling hole pattern for the impingement sleeve, the cooling hole pattern comprising a plurality of cooling holes, at least a portion of the plurality of cooling holes arranged along a circumferential line about a longitudinal direction having size differences that are generally asymmetric about the longitudinal direction, the cooling hole pattern configured to provide a desired operational value for a transition piece; and
manufacturing an impingement sleeve, the impingement sleeve defining the plurality of cooling holes having the cooling hole pattern.

Abstract
An impingement sleeve and methods for designing and forming an impingement sleeve are disclosed. In one embodiment, a method for designing an impingement sleeve is disclosed. The method includes determining a desired operational value for a transition piece, inputting a combustor characteristic into a processor, and utilizing the combustor characteristic in the processor to determine a cooling hole pattern for the impingement sleeve, the cooling hole pattern comprising a plurality of cooling holes, at least a portion of the plurality of cooling holes being generally longitudinally asymmetric, the cooling hole pattern providing the desired operational value.
