摘要

A combustor liner (40) has a stepped combustor liner surface (70) defining a combustion zone (36) and an overhang portion (74) forming an air cooling slot (78). A layer (90) of thermal barrier material is applied to the combustor liner such that at least one portion (96) of the combustor liner receives a layer of thermal barrier material with a thickness (T1) greater than 0.01 inches. Thus, the combustor liner absorbs less heat, and the combustor (30) may operate at higher temperatures. As a result, low cycle fatigue and thermal creep are reduced within the combustor and the life cycle for the combustor is extended.
