Computer Program

Adopting the steady-flow incremental-analysis inclusive of erosive burning, a FORTRAN program has been realized to predict the performance of solid propellant rocket motors having tapered cylindrical grains. All the three phases of operation, namely ignition transient, equilibrium operation, and tail-off transient are included. For easy readability and quick understanding of the program logic, the print version of the source code with detailed comments is given. In order to explain the program capability, the computed performance results of a typical solid rocket motor are presented. In addition, the program source code, the exe file, and examples together with their detailed outputs of six different motor configurations are made available through a suitable digital link.
