Zusammenfassung:	A turbine bucket (32) for use with a turbine engine is provided. The turbine bucket includes an airfoil (66) extending between a root end (88) and a tip end (90). The airfoil includes an outer wall (106) defining a cavity (112) extending from the root end to the tip end, the outer wall comprising a first ceramic matrix composite (CMC) substrate (107) extending a first distance from the root end to the tip end, and an inner wall (104) positioned within the cavity, the inner wall comprising a second CMC substrate (124) extending a second distance from the root end towards the tip end that is different than the first distance.
