Abstract : An empirical model applicable to blast fields generated by recoilless rifles in a free-field environment yields reasonable predictions of transient overpressure resulting from rocket exhaust blast. A second model of the recoilless rifle type is presented for conditions where reflecting surfaces are present. Using the free-field model, the upper bounds of pressure can be predicted at fixed points knowing the rocket chamber pressure and its nozzle exit diameter. (Author)
