Opis:: In this paper are presented some aspects concerning grenade launcher with high-low pressure chambers. On the bases of mathematical model of firing phenomenon for this ballistic system was elaborated interior ballistics software. With the aid of this software were studied the variation of gases pressure and grenade velocity versus time and displacement, as well as the influence of different parameters on main ballistic magnitudes. For an extant such ballistic system, the theoretical results obtained with the aid of interior ballistics software and experimental data are compared.

Opis:: High frequency combustion instabilities imply a major risk for the solid rocket motor's stable operation and they are directly linked to the response of the solid propellant to the pressure coupling. Our paper aims at defining a linearized onedimensional flow study model of the solid propellant rocket motors' disturbed functioning analysis. Experimental researches were done with an adequate setup, built and improved in our lab, functioning on the basis of the nozzle throat intermittent modulating technique developed by ONERA researchers, able to evaluate the propellant response by the interpretation of the pressure oscillations damping in terms of propellant response.
