摘要： An air turbine starter (10) that includes a turbine member (50) for rotatably extracting mechanical power from a flow of fluid (36), where the turbine member (50) is coupled to a drive shaft (60) to provide a rotational output. The air turbine starter (10) further includes a foil-air bearing assembly (70) and a thrust bearing (64) that rotatably support the drive shaft (60).

摘要： An air starter (10, 210, 410) for an engine (14), such as a turbine engine (14), that includes a turbine (50, 250, 450) for rotatably extracting mechanical power from a flow of fluid (36, 236, 436). The turbine (50, 250, 450) includes a drive shaft (70, 270, 470) that can be coupled to an output shaft (80, 280, 480) to provide a rotational output. The interface ((90, 290, 490) between the drive shaft (70, 270, 470) and the output shaft (80, 280, 480) can be offset.

摘要： An air turbine starter (10) for starting an engine (14), comprising a housing (30) having an interior surface defining an interior, at least one turbine member (38) rotatably mounted within the interior about a rotational axis, and having a plurality of circumferentially spaced blades (76), and a containment structure (78, 100, 200, 300) radially overlying and circumferentially surrounding at least a portion of the at least one turbine member (38). The containment structure has a plurality of walls (105, 114, 116, 205, 208, 308) defining a cell structure forming a plurality of cells (118, 210).
