Certainly the technology is available to monitor every part and system on any helicopter. The airframe manufacturers have been doing it in experimental test for years. This paper discusses the use of a sixteen (16) channel vibration monitoring and analysis system permanently mounted on the aircraft. Aircraft vibrations are measured by accelerometers placed at various locations around the airframe, analyzed to obtain frequency information and compared to predetermined vibration limits. FFT’d data is downloaded to a ground based computer for trending to reveal component wear, component faults or assembly/maintenance errors. Continuous monitoring for catastrophic events and rotor track and balance calculators are also considered.
