Multispectral optical depth measurements in post-detonation high explosive fireballs
… depth measurements were made in post-detonation fireballs from five different high explosives. PETN, HMX-based PBXN-5, RDX, an 80% RDX/20% aluminum mixture, and PETN-based Primasheet 1000 explosives were detonated in a 2.18L explosive test chamber. Charges were 125mg or 250mg explosive output …

Experimental investigation of optical and electrical properties of various explosive fireballs
… quantitative experimental data of explosive fireballs at early time scales is crucial for validating 1-D numerical models of spherical charges. While numerical modeling remains a powerful tool for elucidating explosive phenomena, such predictions still require some degree of physical …

Using optical techniques to measure aluminum burning in post-detonation explosive fireballs
… the current study has indicated that explosive fireballs are optically thick. Therefore, external measurements are biased toward conditions near the fireball surface. The objectives of the current study are twofold: (1) to further the understanding of aluminum combustion in an explosive …

Diode laser gas sensing for high-speed temperature and speciation measurements inside explosive fireballs
… and chemistry of the interior of post-detonation fireballs is largely unmeasured at the current time. The present work was carried out in order to develop, demonstrate, and transfer technologies for making cost effective, high-speed, quantitative measurements of temperature and chemical speciation …

Observation and Modelling of Meter-Class Earth impacting Asteroids
… to meter-sized and larger meteoroids observed as fireballs. Fireball event characteristics directly point to the properties and structure of the parent body from which the meteoroid originated. In-atmosphere fireball data paired with in-space observations bring much context to both observations. …

High temperature spectroscopic measurements of aluminum combustion in a heterogeneous shock tube
… observed in propellant plumes or explosive fireballs. The first was a measurement of the alumina emissivity spectral dependence, which is absolutely necessary to make pyrometric measurements. A significant temperature dependence was observed in the emissivity spectral dependence. …

Optical combustion measurements of novel energetic materials in a heterogeneous shock tube
… of generating long lasting high temperature fireballs after the initial blast, which is ideal for defeating biological weapons. The Al-I2 system is similarly suited for the defeat of biological weapons due to high combustion temperatures and the addition of iodine which has known biocidal …
