The Solid Performance Program (SPP)(c) predicts rocket motor performance by calculating deviations from ideal performance by using a series of independent efficiency models. SPP analyzes nozzle and motor performance. The nozzle analysis includes models for describing the 2-D transonic and supersonic steady-state flow field within a given nozzle contour. 1-D models are used to analyze the nozzle wall boundary layer and finite-rate gas phase chemistry.
The motor performance analysis consists of grain design modules and an internal ballistics module. This program is restricted to U.S. companies only and requires DoD (AL/AFSC) approval.
