In this paper, an optimization method for a rocket-refurbishing project is presented. While considering the technical solution the level of reconstruction needs to be decided, from which refurbishment costs are dependent, as well as eventual increase of rocket performances. The idea of rocket motor refurbishment is to extend the life cycle and eventually increase performances for a minimum of an investment. The design shown in this paper is supposed to be an economic solution for the M63 “PLAMEN” 128 mm caliber artillery rocket, resulting in the increase in performance, without significant changes to the construction.


Key words: solid propellant, rocket motor, thrust, internal-ballistic calculation, external-ballistic calculation, modernization, refurbishment, etc.
