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.

A method and system used to control a rotational speed or a torque of an output drive shaft. The output drive shaft being coupled to a turbine engine. The turbine engine including an engine core and an engine starter assembly. The engine starter assembly including an air turbine starter, an output drive shaft and an electric motor.

Turbine engine including an engine starter assembly

An air turbine starter (ATS) for starting an engine, having a stator including a housing having an inlet, an outlet, and a flow path extending between the inlet and the outlet and a rotor including a turbine member defining a rotating axis and having a set of blades at least partially disposed within the flow path. The ATS further including a bearing support structure disposed between the rotor and the stator comprising a first bearing support having a first stiffness (K) and a second bearing support having a second stiffness (K).

An air turbine starter (ATS) for a gas turbine engine having an accessory gear box (AGB) with a lubricant reservoir, the air turbine starter comprising a housing at least partially defining a working air flow path; a turbine section comprising a turbine having an output shaft and a plurality of blades circumferential spaced about the output shaft and at least partially extending into the working air flow path; a drive section having a drive shaft operably coupled to the output shaft to engage the AGB; and a lubrication recirculation circuit fluidly coupled to the lubricant reservoir.

Air turbine starter with lubrication recirculation circuit

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.
