The On Board System for the Evaluation of Rotors Engine and Vibration OBSERVE research and development R and D program was designed to investigate and demonstrate the benefits of onboard data recordingprocessing and rotor tuning equipment for monitoring and diagnosis of mechanical subsystems on the CH-47. The payoffs for such a concept include reduced aircraft vibration levels with extended MTBF of electronics and mechanical system as well as reduced crew fatigue, reduced maintenance flights, and early warning of component failures. This program demonstrates an approach to a practical, automated system which monitors certain cal subsystems, provides inflight vibration and control system status, and prescribes corrective actions to the maintainer. Various monitoring components were developed and integrated to demonstrate this concept.
