Abstract : Minimizing the pressure index of a composite solid propellant is of prime importance as far as the stability of solid rocket motor is concerned. Aluminized and non-aluminized propellants of different formulations are tested in window bomb and the burning rates are analyzed. A constant burning rate is obtained in the pressure range 60-80 bars for the propellants with low fine AP/binder ratio, ultrafine AP and cured by IPDI. This is termed as plateau burning and the pressure index is found to be minimal in the corresponding pressure range. Keywords- Mid-pressure extinction, Pressure index, Plateau burning
