Validation Of The Ballistic Limit Equation For Monolithic Aluminum Shielding At Geostationary Orbital Debris Impact Velocity, Brandon Holladay
Aerospace Engineering
The Cal Poly Electro Magnetic Rail Gun was used to eject a 0.370 gram, rectangular aluminum projectile towards a 1/16 inch monolithic aluminum plate at a speed of 280 ± 50 m/s. The resulting impact left a large attached spall on the back of the shielding. The impact damage was compared to an industry ballistic limit equation for a spherical aluminum projectile of similar diameter and was shown to have slightly less damage than the expected results.
In addition, an aluminum mesh double bumper shield was fired upon in order to verify its higher protection per aerial density as well …
