New approach in numerical simulation of internal ballistics SRM problem [PDF]
In this article new approach of simulating internal ballistics flows in SRM is considered. Two different phenomena should be taken into account for appropriate numerical simulation of internal ballistics problems: grain propellant regression and flow of ...

Investigations of the Influence of Ignition on the Dynamic Vivacity of Propellants [PDF]
The paper presents an attempt to determine the dynamic vivacity functions of propellants with taking into account a parallel burning of the black powder igniter and the tested propellant. The approach is based on presented results of closed vessel tests,

The influence of the internal ballistic pressure on the rifled barrel stress response [PDF]
This paper focused on the 12.7 mm gun barrel stress response caused by the pressure of the gunpowder gases. During the firing process, the barrel is loaded by different mechanical, chemical and thermal loads.

Virtual prototyping of medieval weapons for historical reconstruction of siege scenarios starting from topography and archaeological investigations [PDF]
Chronicles of sieges to castles or fortresses, using “machinae”, can often be found in historical sources. Moreover, archaeological excavations of castles or fortresses has brought to light rocks or projectiles whose carving suggests a military usage ...

Closed Vessel Investigation of Propellant Ignition Process with Using Capillary Plasma Generator [PDF]
Previous published results of closed vessel investigations indicated that classical primers (electric or percussion with black powder bedding) when used with LOVA propellants cause unstable burning, deflagration or even lack of ignition. Capillary Plasma
