Abstract
The Solid Performance Program (SPP) has become the standard reference computer program throughout the United States for predicting the delivered performance of solid propellant rocket motors. The code embodies a methodology for calculating the delivered performance of solid propellant rocket motors prescribed by JANNAF. The nozzle performance methodology starts with the ideal performance and addresses each of the following performance loss mechanisms: finite rate chemical kinetics, nozzle throat erosion, nozzle submergence, nozzle flow divergence, two phase flow, combustion efficiency, and the nozzle wall boundary layer. The Grain Design and Ballistics (GDB) module calculates the ideal pressure-thrust history, and subsequently modifies these values based on the nozzle performance efficiencies. The GDB module combines existing 3-D grain design and ballistics methods with modern graphics and ease of use to provide a tool which allows even novice users to obtain successful results.
