High-Resolution Measurement Techniques for High Explosive Internal Pressure and Temperature for Lethality Assessment

Corvid Technologies will develop in-situ instrumentation to measure key physical states in reacting high explosives. The emerging measurement capability will provide state information to support lethality analysis by enabling equation of state development for computational models, as well as fast-running engineering codes for evaluating HE response to stimuli. Development of internal temperature and pressure sensors will be the focus of the innovative research. Design goals are to develop sensors with minimal impact on the material response with high spatial and temporal resolution. Sensor design will focus on optical, electromagnetic, and piezoelectric sensors. Each sensor approach has the potential to collect pressure data, temperature can be measured using optical methods. Down selection will be done using decision matrix based on deployability, temporal resolution, spatial resolution, accuracy, and cost. Expect peak pressures of 400 kbars and peak temperatures of 7000 K. Our teaming arrangements enable the employment of high speed optical data capability and optical fiber expertise that will be critical for development of optical sensors. Corvids experience in studying reactive materials from no reaction, deflagration, low order, to a high order response and experience in sensor development/deployment on reactive tests will be leveraged in the development of these sensors.
