Wireless Vibration Monitors for Advanced Propulsion Systems Ground Testing

Cost effective research and development of NASArsquo;s new propulsion capabilities places a premium on maximizing the return spent on ground testing.nbsp; Tests must yield high-quality results both in data and subsequent analysis, fit into aggressive development schedules, and allow developers to minimize costly test-fail-fix cycles.In this Phase I project, Lorand Technologies is proposing to adapt its core wireless and battery-less vibration sensing technology for application in propulsion systems ground testing. The enabling component of our technology is an innovative sensor design that converts applied acceleration to a shift in the resonant frequency of a micro-resonator that could be interrogated wirelessly and passively. For this application, the material used in fabrication and packaging of the sensor will be chosen to withstands operation temperatures of ~600C and above.
