Accelerometer systems are commonly employed in aviation health and usage monitoring systems (HUMS) and other aviation diagnostic and prognostic system approaches. Over the past decade, an research and development (RD dynamic range; amplitude frequency response; phase frequency response; amplitude non-linearity; transverse sensitivity; and mass and size. The environmental parameters include: temperature; thermal transmit sensitivity; base strain sensitivity; electromagnetic sensitivity; acoustic sensitivity; radioactive environments; humidity; grounding/electrical isolation; and placebo/noise monitor control. Additionally, other factors are addressed including bandpass differences in terms of total bandpass, high frequency performance and low frequency performance. Observations are also included that address potential user interest beyond performance. Examples include implementation alternatives, integration considerations, cost considerations and an outline of the remaining work that need to be accomplished for introducing a new generation of "advanced health and usage monitoring systems". |
