Abstract
Mechanical and burning characteristics of foamed propellants used as combustible cartridges have to be well composed in order to provide their proper function in a weapon. A basic problem, which emerges when mechanical stability at the shot is unsufficient, is a phenomenon called gas-slipping. Gas-slipping occurs when a cartrigde cannot withstand the boost caused by the igniting-process. In this case gas gets (“slips”) from the cartridge chamber into the gun barrel before the projectile arrives. This effect causes undesirable impacts on a weapon, like low projectile velocities and low reproducibility of shot-series. Especially the temperature behaviour of the mechanical properties of foamed propellants plays an important role in these considerations.
