Mathematical modeling of rail gun
… conductivity at the interfaces between the rails and the armature of a rail gun are critical issues. This thesis, using finite element method, estimates the former by solving the proper multiphysics governing equations, along with exploiting the contact theory between flat surfaces. A …

Barrel wear reduction in rail guns : an investigation of silver paste liquid-metal interface
… silver paste has on the damage at the projectile-rail interface of a 4" long rail gun test section. Projectiles (0.635 x 0.635 x 0.953 cm) were pushed through the rail test section at 34 Å 19 m/s, while average current densities of 18-32 kA/cm2 was passed through the projectile - rail interface …

Analysis of the Mechanically Choked Ram Accelerator
… the baffled tube section of the system, and railed tube operation, which would be needed to fully validate theoretical claims, was unable to be successfully achieved. Regardless, the test series showed promising results and further testing will be required to validate the mode’s effectiveness …

Analysis of Electromagnetic Launcher Design and Modeling
… to gain a deeper understanding of the nature of railguns. The expressions are refined for ease of use and then compared to electromagnetic simulators that solve complex equations that arise from different rail geometry. Further simplifications lead to an expression for the final velocity of the …

Design, Fabrication, and Testing of an EMR Based Orbital Debris Impact Testing Platform
… the changes made from Cal Poly’s initial railgun system, the Mk. 1 railgun, to the Mk. 1.1 system, as well as the design, fabrication, and testing of a newer and larger Mk. 2 railgun system. The Mk. 1.1 system is developed as a more efficient alteration of the original Mk. 1 system, but is …
