An inquiry into the viability of solid rocket motors at high altitude and near space conditions was proposed to maintain performance similar to ambient. This project was meant to evaluate the types of metrics to use to validate similarity, and propose material properties to test, along with suggested mixes of propellant candidates. This included looking into isophorone diisocyanate, modified methylene diphenyl diisocyanate, and dimeryl diisocyanate curatives at varying solids loading in addition to trimethylolpropane under uniaxial tensile loads at -50 ℃ to simulate upper atmosphere firing of the motor. Stress-strain data, percent elongation, ultimate tensile strength, and work of fracture were then collected and determined to get an idea of what may provide the best benefit of performance at low temperature.
