A versatile digital computer program was developed to provide linear burning rate information on propellants based on pressure-time records obtained from closed bomb firing. Some of the unique features of the program are: a treatment of heat loss based on radiative and convective heat transfer, capability of using single valued or tabular thermodynamic input, allowance for web deviation in the propellant sample, allowance for ignition deviation (flame spread) of the propellant sample, allowance for possible simultaneous burning of propellant and ignition aid, allowance for tabular input of propellant surface versus mass fraction burned (to accommodate unusual geometries), and capability to treat vented vessel operations. The program was set up to operate on an interactive basis on a PDP 11/20 laboratory computer. In practice, once the program is called, the operator is guided in his choice of parameters (thermochemistry, heat loss, ignition deviation, etc.) by a series of prompts. A program overview is presented along with a description of equations, a derivation of the equations, and copies of program output and program listing. (Stoehr)
