Abstract: An air turbine starter for starting an engine having a housing that defines an inlet, an outlet, and an air flow path extending between the inlet and the outlet. The housing includes a seal that defines at least a portion of the air flow path. A drive shaft rotatably coupled to a turbine defines a rotating axis. The turbine includes circumferentially spaced blades at least partially disposed within the air flow path. At least one bearing rotatably supports the drive shaft. A bearing support structure is located between the at least one bearing and the seal. A fluid damping assembly includes one or more conduits that fluidly couple a fluid source to a fluid reservoir.

Abstract: An air turbine starter with a housing; a turbine member located within the housing; a drive shaft operably coupled to the turbine member, and having an interior portion. The air turbine starter output shaft extending between a first end and a second end, the output shaft movable between a first position, where the first end is coupled to the engine, and a second position, where the second end is retained within the interior portion and the first end is uncoupled from the engine. A decoupler assembly is included for decoupling the output shaft from the engine.

Abstract: An air starter for starting a turbine engine that includes a housing, a turbine, an output shaft, and at least one bearing. The housing can define an interior where the turbine couples to the output shaft. A primary air flow path extends through the housing where air from the turbine can be exhausted through a primary outlet or a cooling outlet.

Abstract: An air turbine starter for starting an engine, comprising a housing defining an inlet, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of gas there through. A turbine member is journaled within the housing and disposed within the flow path for rotatably extracting mechanical power from the flow of gas and a gear train is drivingly coupled with the turbine member. A drive shaft is operably coupled with the gear train, and a decoupler is selectively coupled to the drive shaft for decoupling the air turbine starter from the engine.
