Ultrasonic Measurement System Ultrasonic Measurement System. Ultrasonic measurement system will enable simultaneous measurement of temperature, velocity and density fields through a grid of ultrasonic sensors. This method incorporates a theoretical approach and machine learning techniques to develop a physics-informed data-driven calibration and operation workflow. This allows at least ten times faster data processing times as well as potential capability of transient measurements and solid particle detection. The system can also be utilized for health monitoring. This measurement technique is in line with the “air-breathing propulsion” core competency of GRC. However it can also enables next generation space data processing with higher performance computing capable of operating in harsh deep space environments.
