Mechanical Component Diagnostic System.

摘要

The Mechanical Component Diagnostic System (MCDS) research and development (RD) program was designed to investigate and demonstrate the benefits of onboard data recording/processing and rotor tuning equipment for monitoring and diagnosis of mechanical subsystems on rotorcraft. The payoffs for such a concept include reduced aircraft vibration levels (with extended MTBF of electronics and mechanical systems 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 mechanical subsystems, provides inflight vibration and control system status, and prescribes corrective actions to the maintainer. Various monitoring components were developed and integrated to demonstrate the concept.
