AIR TURBINE STARTER WITH NOZZLE RETENTION MECHANISM

An air turbine starter (10) having a housing (78) defining an interior (28) with a primary inlet (32) and a primary outlet (34) to define a primary air flow path (36) from the primary inlet (32) to the primary outlet (34). A nozzle (42) is located within the interior (28) and has circumferentially spaced vanes (50). A shroud (44) is also located within the interior (28) and circumscribes at least a portion of the vanes (50). A retention mechanism (44) constrains the axial movement of nozzle (42).
