The vacuum specific impulse, density vacuum specific impulse, and solid exhaust products were examined for several propellant\nformulations based on the pyrophoric material triethylaluminum (TEA) using CEA thermodynamics code. Evaluation of TEA\nneat and mixed with hydrocarbon fuels with LOX, N2O, N2O4, liquefied air, and HNO3 were performed at stoichiometry. The\nvacuum specific impulse of neat TEA with N2O is comparable to that of nitric acid with the same, but the N2O formulation will\nproduce slightly less solid products during combustion. Additionally, N2O-TEA propellants have vacuum specific impulses and\ndensity vacuum specific impulses within 92.9% and 86.7% of traditional hydrazine propellant formulations under stoichiometric\nconditions.
