|Abstract:||Data on ambient temperature burning rates for an aluminized HTPB composite propellant family with bimodal AP and a total solids loading of roughly 80% over the pressure range from 35 to 105 kg/cm2 have been reported. Data are also reported for the additive free base line formulation and formulations with individual rate modifying additives (Fe2O3, copper oxide, CaCO3, SrCO3) at 2% level. Results have been correlated with rate expressions of Summerfield, Rice, Rastogi and several other empirical relations and relative merits of different equations have been assessed. Further, the experimental data of Blair on pressure and temperature dependence and of Singh on formulation dependence of burning rate have also been analysed. The results show that burning rate is directly proportional to (Ti)1/4, in agreement with the prediction based on burning rate expression of Rastogi et al. (Ti, is the initial temperature in kelvin).|
