Ultrasonic Embedded Temperature and Recession Monitor

Physical Sciences Inc. (PSI) has been awarded a contract from the U.S. Navy to develop a non-intrusive recession rate and surface temperature monitoring system that will be operational in flight test environments.

PSI’s monitoring system will address the Navy’s need of an in-flight diagnostic tool capable of measuring surface temperatures and recession rates of various materials and geometries of the Thermal Protection System (TPS) of hypersonic missile surfaces during flight tests. Atmospheric friction heating dictates varying requirements for aircraft surfaces, including high temperature survival and/or sacrificial material ablation over the flight profile.

PSI’s recession rate and temperature sensor targets the monitoring of aircraft structures, ablative edges, engine flow-paths, rocket nozzles, and other aerodynamic surfaces where extreme high-temperature conditions exist. The sensor system will help in advancing both ground-based and in-flight testing capabilities, materials research and fabrication techniques, and optimization of thermal protection system surface geometries for efficient cost/performance of next-generation hypersonic vehicles.
