Abstract : The final report consists of AIAA papers. The report presents an analytical performance prediction methodology for annular propulsion nozzles with and without swirl introduced in the combustor upstream of the nozzle. Four types of swirlers were investigated: free vortex, constant angle, forced vortex and Rankine vortex swirlers. For the no-swirl case thrust efficiencies and static pressure profiles from cold flow testing of selected nozzles are summarized and compared to the predictions.... Ramjets, Supersonics.
