Abstract: A reproducible, accurate, ballistic evaluation system for solid propellants was developed. Particular attention centered on an accuracy level of 0.5 percent or better on specific impulse (Isp). Evaluation of new propellants by their manufacturers had resulted in a multiplicity of definitions and mathematical correction factors which obscure actual performance results and complicate qualitative comparison of competitive propellants. An industry survey determined desirable standard motor system parameters and prevailing practices. From industry, best practice such as 1,000 psi combustion pressure and 15 degree nozzle exit half-angle expanded to local ambient pressure, were adopted in the motor and system design as far as possible. Other system parameters were selected by the assigned design engineer/manager; 2Lt H. Gale. Eight months after assignment, first firing was in September, 1961. Twelve firings of two propellants were made for motor and system evaluation. All objectives were successfully achieved or exceeded. Calibration firings established the confidence level and accuracy of the system prior to evaluation of industry propellants.
