AbstractIn this Phase I program, we develop and validate an acoustic concept that is capable of measuring interior temperatures in complex munitions propellants. The measurement technique is based on ultrasonic thermometry methods. Using sensors located on the exterior surface, the variation in propagation time is used to estimate the internal temperature. No modification of the component is required. In laboratory studies we address the issues of echo identification, optimal operating frequency, coupling, calibration, and repeatability. A series of laboratory studies validate the concept and demonstrate the potential for implementation for real-time monitoring of internal temperature. Successful demonstration of the concept and measurement methods in the Phase I program will provide the basis for full-scale prototype systems to be completed in Phase II
