Abstract
An innovative system that allows the measurement of velocity, position, temperature and pressure during burn, deflagration and detonation of energetic materials has been developed. An initial demonstration of this system has been able to measure pressures up to 1,200,000 psi, and temperature changes of 400 °C over a period of 25 microseconds. Both measurements were instrument limited. Improved instrumentation will allow extensions to 4,000,000 psi measurements and enhanced resolution of over and order of magnitude. This is the first time to our knowledge that measurements of velocity, position, temperature and pressure have been made interior to energetic materials during burn, deflagration and detonation. Immediate application areas include assessment of the performance of solid rocket motor propellant materials, insensitive munitions and detailed measurements of high speed, detonation events.
