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 highly energetic materials
during burn, deflagration and detonation. The technology is in its very early stages. It has great potential to make
important near term measurements with significant further improvements being made as the technology begins to
mature. Immediate application areas include assessment of the performance of solid rocket motor propellant materials,
insensitive munitions and detailed measurements of high speed, energetic events. Additionally, continuous detonation
wave velocities were measured inside of large explosive charges greater than 200 millimeters in length.
