Force and Sound Pressure Sensors Used for Modeling the Impact of the Firearm with a Suppressor

Abstract

In this paper, a mathematical model for projectiles shooting in any direction based on sensors distributed stereoscopically is put forward. It is based on the characteristics of a shock wave around a supersonic projectile and acoustical localization. Wave equations for an acoustic monopole point source of a directed effect used for physical interpretation of pressure as an acoustic phenomenon. Simulation and measurements of novel versatile mechanical and acoustical damping system (silencer), which has both a muzzle break and silencer properties studied in this paper. The use of the proposed damping system can have great influence on the acoustic pressure field intensity from the shooter. A silencer regarded as an acoustic transducer and multi-holes waveguide with a chamber. Wave equations for an acoustic monopole point source of a directed effect used for the physical interpretation of pressure as an acoustic phenomenon. The numerical simulation results of the silencer with different configurations presented allow trends to be established. A measurement chain was used to compare the simulation results with the experimental ones. The modeling and experimental results showed an increase in silencer chamber volume results in a reduction of recorded pressure within the silencer chamber.

Performance Analysis of Different Firearm Suppressor Structures

“…During the gunshot, the bullet rapidly exits the firearm and the suppressor at the end of the barrel, leaving a hot trail of expanding gases behind it. The strong pulse sound is directional and can travel great distances harming the shooter as well as anyone or anything standing nearby [20][21][22]. Studies show that suppressors can have a pulsed sound suppression effect of 17-36 dB [4,5,7,9,11,14,18,19].…”
