Abstract: An air turbine starter that includes a housing. The housing can circumscribe a turbine coupled that is coupled to a gear train in a gear box via a drive shaft. The gear train can couple to an output shaft via at least a carrier. The air turbine starter can include at least a first bearing assembly and a second bearing assembly to rotatably support the drive shaft and the output shaft.

Abstract: A starter/generator system that includes a first and second electric machine. The first electric machine has a first rotor and a first stator where the first rotor is adapted to receive kinetic energy and the first stator includes a first set of windings. The second electric machine has a second rotor rotatable and a second stator. The second stator is fixed relative to the first stator and the second stator includes a second set of windings.

Abstract: A method for slow starting a reciprocating engine having a crankshaft, piston, and piston chamber is disclosed. The method includes applying a force to the crankshaft, sensing an engine characteristic, and determining if an error or fault is present in the engine.

Abstract: Systems and methods for starting an engine on an aircraft are provided. One example aspect of the present disclosure is directed to an integrated starter for starting an engine on an aircraft. The integrated starter includes an air turbine starter. The integrated starter includes a starter air valve integrated with the air turbine starter. The integrated starter includes a controller configured to control the starter air valve. The starter air valve can be movable between a first position and at least a second position to regulate the flow of fluid into the air turbine starter. An output torque of the air turbine starter can be dependent at least in part on the flow of fluid into the air turbine starter.

Abstract: Systems and methods for detecting an issue with a starter are provided. One example aspect of the present disclosure is directed to a method for detecting an anomaly with an air turbine starter. The method includes receiving, by one or more controllers, data indicative of a frequency associated with an integrated air turbine starter from one or more sensors located on a stationary portion of the air turbine starter to monitor a rotating portion of the air turbine starter. The method includes determining, by the one or more controllers, an anomaly associated with the integrated air turbine starter based at least in part on the data indicative of the frequency. The method includes providing, by the one or more controllers, a notification indicative of the anomaly associated with the integrated air turbine starter.

Abstract: Systems and methods for starting an engine on an aircraft are provided. One example aspect of the present disclosure is directed to a method for starting an engine using an integrated starter. The integrated starter includes a starter air valve and an air turbine starter. The method includes receiving one or more signals indicative of one or more parameters. The method includes determining a valve setting for the starter air valve based at least in part on the one or more signals indicative the one or more parameters. The method includes providing one or more control signals to adjust a position of the starter air valve based at least in part on the valve setting. The position of the starter air valve regulates the flow of fluid into the air turbine starter.
