The Effect of Gaseous Additives on Dynamic Pressure Output and Ignition Sensitivity of Nanothermites

ORAL

Abstract

This contribution addresses important combustion characteristics of nanothermite systems. In this research the following nanothermites were investigated: a) Al-Bi$_{2}$O$_{3}$, b) Al-Fe$_{2}$O$_{3}$ and c) Al-Bi$_{2}$O$_{3}$-Fe$_{2}$O$_{3. }$The effect of various gasifying additives (such as nitrocellulose (NC) and cellulose acetate butyrate (CAB)) as well as reactant stoichiometry, reactant particle size and shape on processability, ignition delay time and dynamic pressure outputs at different locations in a combustion chamber will be presented. In addition, this contribution will report electrostatic and friction sensitivities of standard and modified nanothermites.
