RESUMO

The basic trajectory model is the standardized Modified Point Mass trajectory model where, in the first phase, the base drag reduction and the gas generator mass flow rate are calculated. 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.
