A cascade arc facility has been constructed at UTSI to study the effect of nonequilibrium transport properties in hydrogen-nitrogen arcjet propellant plasmas. These studies will be used to guide development of the physical models required for further development of arcjet computational codes. The cascade arc has been operated on hydrogen at 50 Amps and at pressures of 13.8 kPa (2.0 psi) and 41.3 kPa (6.0 psi). Preliminary spatially resolved spectral data at these conditions have been collected for the Balmer Hα line. Theoretical, Stark broadened, Hα lineshapes have been fitted to the experimental lineshapes to determine the radial distributions of electron number density. These number densities were compared to values taken from the nonequilibrium and equilibrium cascade arc simulations. The simulations underpredict the peak experimental number densities; however, the profile of the nonequilibrium solution matches the experiment.
