Air Vehicle Diagnostic System: CH-46 Aft Main Transmission Fault Diagnosis-FinalReport

摘要

The goal of the helicopter drive system condition monitoring component of the AirVehicle Diagnostic System (AVDS) program is to develop technology that will facilitate transition to 'condition-based maintenance' (CBM) for these components. The specific system requirements as stated in the AVDS Execution Plan are as follows: (1) Detect and classify gearbox faults in real time in flight. (2) Cope with variations between gearboxes. (3) Perform diagnostics in a variety of flight regimes. (4) Reduce false-alarm rates. (5) Reduce maintenance costs and facilitate transition to CBM. This report describes the performance of a system developed by NRaD that meets these requirements.
