Novel Propellant Formulations Containing Nano-particulates
Agency / Branch:
DOD / ARMY
Minimum signature propellants are listed as hazard class 1.3 explosives that consist of nitrocellulose/nitramine-type propellant compositions. Nano-sized particles can be incorporated into these minimum signature propellant formulations for the purpose of improving the specific impulse, increasing the burn rate and diminishing the propellant sensitivity, due to their size, shape, surface area, high surface-to-volume ratios, chemical structure and functionality. These nano-sized particles contain functionalized reactive sites that can effectively chemically bond and physically bind to the propellant matrix formulation. In this Phase I program, Infoscitex Corporation will incorporate and disperse these functionalized nano-sized particles into minimum signature propellant formulations to improve their physical properties. The propellant physical properties (burn rate and burn rate exponent, specific impulse and sensitivity) will be measured by differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and light microscopy. Upon successful completion of Phase I, the Phase II and Phase III activities will focus on the scale-up, manufacture and commercialization of the minimum signature propellants containing the nano-sized particles.
