The goal of this research was to experimentally demonstrate the feasibility of a cylindrical shock wave to serve as the major pressure recovery mechanism for either cylindrical gas dynamic lasers or chemical lasers. An analysis was conducted to determine the minimum distance between the nozzle exit cylinder and shock wave location, r sub m-r sub e prime, required for power extraction. A cylindrical nozzle array was designed using the axisymmetric method of characteristics for a Mach number of 4.5 with a flexibility of other Mach numbers. A chamber incorporating end wall boundary layer bleed and ejectors for back pressure control was designed and built.
