Air Turbine Starter (ATS) systems are provided, as gas turbine engines including ATS systems. In one embodiment, a gas turbine engine includes an accessory gearbox (AGB) and an integrated Air Turbine Starter (ATS) system. The AGB includes a gearbox gear train within a gearbox housing. The integrated ATS system is removably installed on the AGB and includes an ATS having an air turbine and an output shaft coupled thereto. An ATS clutch module is coupled to the ATS output shaft. The ATS clutch module is further within the gearbox housing and mechanically couples the ATS output shaft to the gearbox gear train when the integrated ATS system is installed on the AGB.

Air turbine starter systems including gearbox-integrated clutch modules and gas turbine engines employing the same

Line Replaceable Unit (LRU) health nodes are provided, as are methods for determining maintenance actions with respect to LRU health nodes. In one embodiment, the LRU health node includes a passive Radio Frequency identification (RFID) module having an RFID memory and an RFID antenna coupled thereto. The LRU health node further includes a mass storage memory, a sensor configured to monitor an operational parameter of an LRU and generate a corresponding output signal, and a health node controller operably coupled to the passive RFID module, to the mass storage memory, and to the sensor. The health node controller is configured to: (i) record the output signal generated by the sensor in the mass storage memory as time-phased sensor data, (ii) derive health summary data from the time-phased sensor data, and (iii) store the health summary data in the RFID memory.
