Abstract : A computer code is presented for solving the equations of the unified solid propellant ignition theory reported in Part 1 of this series of reports. The computing algorithm is based upon a predictor-corrector version of the Crank-Nicholson implicit method applied to the system of parabolic partial differential equations. Coding is in FORTRAN V language. Use is made of PARAMETER statements to effect variable dimensions and of NAMELIST statements for convenience in data input. Internal subroutines are freely used to overcome increased computer times which attend the use of argument lists associated with external subprograms. Approximately twenty-three thousand decimal locations are required for the compiled program, not including plotting routines, which would be dependent upon a particular computer installation.
