| description | Introduction/purpose: In this paper, the influence of muzzle velocity and the
initial friction between the sabot and the penetrator of a sub-caliber bullet
on the separation process was investigated. A special armor-piercing bullet
was chosen as a research object.
Methods: A hybrid approach was applied in the study to solve the set tasks.
In the first place, the equation system describing the motion of the sabot
and the penetrator was established analytically. The aerodynamic drags
acting on the sabot and the penetrator were then obtained numerically
using CFD methods. Eventually, the equations of motion of the sabot and
the penetrator were solved using the Runge-Kutta method to analyze the
effect of the bullet muzzle velocity and the initial friction of the sabot and the
penetrator on the separation process.
Results: The research results have shown the significant influence of the
bullet muzzle velocity and the initial friction on the parameters of the sabot
and the penetrator at the very moment they completely separate from each
other. Based on the obtained data, weapon designers can appropriately
select the ballistic and structural parameters for the bullet.
Conclusion: The hybrid approach presented in this paper is effective in
studying the separation process of armor-piercing saboted bullets. The
research results are useful contributions to the field of sub-caliber
ammunition. The presented method can be applied in the design process
of armor-piercing saboted projectiles of different calibers. |
