IHPRPT Improvements to the Solid Performance Program (SPP)

Abstract : The JANNAF Solid Performance Program (SPP) is being upgraded as part of the Air Force Research Laboratory's IHPRPT Modeling and Simulation effort. This paper describes the improvements to the nozzle performance modules within the SPP. Both full and parabolized Navier-Stokes solvers have been added to the code and are described in this paper along with a comparison of results.
