Anticipated Benefits
1) Increase productivity and utility of existing test facilities by measuring noise intensities directly without requiring anechoic treatments. 2) Measure and characterize the noise generation of rotorcraft blades using lagrangian frame of reference. 3) Provide noise intensity distribution and mapping to help calibrate, and focus and optimize CFD programs. 4) Characterize characteristics of jet engines, both near and far-field noise 5) Monitor and characterize engine internal exit characteristics with sensors mounted on engine cowls 1) Nuclear power steam generator performance monitoring and prognostics 2) Oil Industry industrial component monitoring for fault conditions and prognostics
