Design of New Parameters 9mm Luger Cartridge for Using in Combination with the Short Gun Suppressor

Absztrakt

The aim of this work is to design new parameters of the 9mm Luger cartridge for using in combination with the short gun suppressor. In the theoretical part is clarified the origin and types of unmasking effects, which occurs during the gunshot. We focus on the sound effect and the way it can be suppressed. Subsequently, we describe suppressors and silencers and their types. Furthermore, we parse the efficiency of bullet and ways of changing parameters of cartridges in order to achieve the desired efficiency.
In the practical part, we implement internal ballistic calculation, in order to design the parameters for 9mm Luger cartridge, with the aim to reach the velocity of bullet below the sound speed to ensure a sufficiently effective removal of the sound effect of the gunshot when the suppressor is used. The results obtained from designed samples are compared with the standard 9mm Luger cartridge, with focus on the energy of the bullet and also evaluation our designed samples in terms of the functional cycle of weapon.
