It may be expedient to integrate the preliminary design of solid propellant motors (SPM), especially the motors aimed for launching, into the overall design, when lifting vehicles are created with SPM included in their structure. This implies that the internal ballistic calculations have to be provided by utilizing the engineering mathematical models, the only complex point of which is the evaluation of the burning surface of the charge under consideration. A method for the computation of this relation is presented in this work, which optimizes one of the previously proposed methods as in efficiency of calculations so in the precision of the results.
