Role of Pressure and Aluminum Size in Solid Propellant CCP Generation [PDF]

, 2017
Aluminum combustion in solid propellants generates condensed products leaving the burning surface. The population of this particles is quite wide, spanning from smoke-oxide to molten metal drops.

Resistive Heating and Thermal Decomposition of an Additively Manufacturable Electrically Conductive Explosive

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 1, January 2025.
Abstract The ability to transmit electrical signals through high explosive charges without using dense metal conductors could enable continuous monitoring of explosive charges with internally embedded sensors. With the sensor materials themselves being energetic, the impact on the intended detonation performance of the charge can be minimized. Embedded
