.155 Mm, Artillery Congruent Module Installed A Feasibility Study Of Medicine,

This article has studied the feasibility of uni-modular charge on GC-155mm artillery using partly block-combustion technology, additive charge technology and LTSC (low temperature sensitivity charge) technology based on the double-modular charge system with modifying its original charge means and the type and types of the propellants.The combustion performances of the mixed charge under fixed volume are studied with the closed-vessel experiments. The rules of perforation exposing process and combustion of mixed charge under different temperature, propellant type and web size are compared.The physical process and ballistic performances of mixed charge are analyzed usingballistic experiments systematically. The influences of the mixing proportion and burningsurface of main propellants and coated propellants, the web size and perforation number of main propellants, the coating layer thickness of coated-propellant and the chargeweight of small-granule propellant on ballistic performances is discussed in detail.4.The combustion physical model of mixed charge has been proposed and a classical interior ballistic model of mixed charge has been established based on the theoretical and experimental study. This model has been programmed and calculated. The calculating results show that the assumption of mixed charge combustion process is reasonable and the mathematical model is valuable for the calculation of mixed charge including coated-propellant.
