The burning rate is expressed as a function of the upstream atmospheric pressure and operating generator temperature. The base drag reduction coefficient is expressed as a function of Mach number and characteristic mass flow rate. Following several firing campaigns, the coherence of the model with firings has been verified. %8 1991-01-01
