Study of the Influence of Erosive Combustion of Solid Fuel on the Intra-Ballistic Parameters of a Jet Penetrator.

The mechanism of erosive combustion of gunpowder and its consideration in solid propellant rocket engines are analyzed. The issues of the influence of erosive combustion of a solid fuel on changes in the thrust of a jet penetrator engine are considered. A mathematical model is presented for calculating changes in parameters of the intra-chamber process over time, taking into account their changes along the length of the charge for an engine with a freely inserted tubular charge. The obtained calculation results confirm the significant influence of the charge temperature on the intra-ballistic parameters of the penetrator. [ABSTRACT FROM AUTHOR]
