A Comprehensive Analysis of the Internal Ballistic Effects of Riffled Barrels
Öz
Abstract
This study examines how rifled barrel geometries influence internal ballistic behavior under high-pressure conditions through explicit dynamic simulations in ANSYS. Barrel length, rifling angle and configuration, propellant mass, and projectile nose curvature radius were varied individually across seven models to isolate their effects. Results show that longer barrels increase muzzle velocity but also deformation; larger rifling angles improve rotational stability while reducing linear acceleration due to frictional losses; changes in nose curvature radius significantly alter both deformation and velocity; and increased propellant mass enhances acceleration but may reduce energy efficiency when mismatched with barrel geometry. Overall, the study offers essential guidance for understanding and optimizing rifled barrel parameters in internal ballistic applications.
