Abstract:

Among the many systems being investigated in the effort to develop a thermochemically pumped electronic transition laser, the NF radical has shown high promise. This report describes the modeling completed to evaluate an NF mixing concept. Calculations were made with varying expansion ratios, both in the nozzle and cavity, to determine the optimum throat pressures, throat temperatures and element lengths. The mixing concept as described is very promising and could last if the optical path length is long enough. Author
