For these reasons it is important to determine not only the performance such as specific impulse (Isp), density specific impulse ([rho]Isp), and ignition delay of TEA with a given oxidizer, but also the effect a solvent has on the system.
It was shown that nitrous oxide is comparable to nitric acid in terms of specific impulse, and in terms of density specific impulse nitrous oxide is comparable to LOX.
