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. A gear train is drivingly coupled with the turbine member, a drive shaft is operably coupled with the gear train, and an output shaft is selectively operably coupled to rotate with the engine via a decoupler.

Abstract: A method and decoupler for disengaging an output shaft from an engine in a back drive event with a backdrive decoupler. The backdrive decoupler includes a threaded shaft and a retention mechanism selectively coupling the output shaft to the threaded shaft. In a backdrive event, the decoupler decouples the output shaft from a drive shaft.

Abstract: An apparatus for an air turbine starter for an engine. The air turbine starter includes 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 having a turbine output shaft. The air turbine starter further includes a planetary gear system drivingly coupled with the turbine output shaft and including a sun gear, a ring gear mounted to the housing, and a set of planetary gears operably coupling the sun gear and the ring gear with the sun gear is coupled to the turbine output shaft.

Abstract: A method and decoupler for disengaging an output shaft from an engine in a back drive event with a backdrive decoupler. The backdrive decoupler includes an output shaft, drive shaft wherein the output shaft is selectively coupled to the drive shaft. Permanent magnets are used to transmit torque from the drive shaft to the output shaft. In a backdrive event, the decoupler decouples the output shaft from the drive shaft by uncoupling the torque transfer.

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.
