Zusammenfassung:	An impingement sleeve (34) and methods for designing and forming an impingement sleeve (34) are disclosed. In one embodiment, a method for designing an impingement sleeve (34) is disclosed. The method includes determining a desired operational value (110) for a transition piece (26), inputting a combustor characteristic into a processor (112), and utilizing the combustor characteristic in the processor to determine a cooling hole pattern (56) for the impingement sleeve (34) (114), the cooling hole pattern (56) comprising a plurality of cooling holes (52), at least a portion of the plurality of cooling holes (52) being generally longitudinally asymmetric, the cooling hole pattern (56) providing the desired operational value.
