Accurate usage information collected by Health and Usage Monitoring Systems (HUMS) coupled with improved structural fatigue life calculation methodologies promise to reduce helicopter operational and support costs while maintaining current flight safety levels. Current fatigue life calculations assume worst-case flight profiles in determining component life. This approach may be outdated or not reflective of actual aircraft usage. IAC has developed processing to include a low cost regime recognition and aircraft gross weight estimation capability as an extension to the US Army's Vibration Management Enhancement Program (VMEP). IAC's approach relies on multi-sensor data fusion technology and flight parameters collected by the VMEP to provide an accurate flight regime calculation. Recording time in particular flight regimes has the potential of extending aircraft component life without changing proven lifing models. The regime recognition system has been implemented with the current release of IAC's VMEP systems. Presented here is the methodology, development and visualization tools, and results for using the system on CH-47 aircraft.
