Abstract:

Five test nozzle configurations have been selected for design and testing to support the requirements of this contract. All designs are of the converging-diverging supersonic type. Two are of straight conical divergent wall design, one each for a design Mach number of two and of four. The remaining 3 nozzles consist of one each axi-symmetric shock-cancellation type, free expansion type, and a unique plug nozzle. Fabrication of all designs is complete but for the plug design. Testing has begun and preliminary data is herein presented. A literature search was conducted and a summary of reports on hand is presented. Also, a theoretical nozzle performance prediction analysis has been started. No serious problems are foreseen and the program will be completed on schedule.
