On the Characterization of Propulsive Powders: Performance Calculation of Congolese Compositions

P.G.A-Ponga-Abwe

Abstract: In this study we sought to corroborate in a comparison the calculated and / or experimental theoretical values of the solid propellant powders prepared by us with the experimental data of the few typical powders reported in the literature taken as references. It is a question of studying a possible substitution of the Chinese propellant by the Congolese propellant. Experimental trials were conducted at two levels and in two stages - Initially the tests were carried out in open field - In the second phase we conducted the tests in combustion chambers with the dimensional characteristics of a rocket 107 of Chinese manufacture, our reference, and Congolese manufacture. We controlled and varied the particle size of the constituents, composition by weight of constituents, propellant / engine structure ratio, aging time, combustion area, fill factor and binder nature or composition to determine or Calculate the parameters influencing propellant performance. Thus reaction time (ignition or priming), thermal energy, texture, pressure, specific pulse, volume of ejection gas, momentum, energy value and kinetic energy have Were calculated to assess physical homogeneity, stretch limiting force and elongation, compressive and deforming force, thermal expansion, thermal conductivity, diffusivity and chemical stability.
