Experiments have shown that solid propellants can substantially supplement and prolong the positive pressure pulse in a standard shock tube, provided that proper design and operational procedures are observed. The extra energy from the solid propellant allows for expedient simula tion of nuclear blast wave conditions within the tube. Three types of solid propellant rocket motors from standard stock were utilized. Pres sure, temperature, and velocity characteristics of gas flow generated by the motor and discharged through a nozzle into the tube were recorded as a function of time at several locations down the tube. In addition, a unique technique for generating a shock wave at a preselected time during the high velocity gas flow was developed.
