Moving from my Undergrad Final to a Graduate project, I was asked to come up with a concept military shelter -
“Tip of the Spear” operations.
The main testing goal for the Composite System was for it to provide protection from 2582 ft lbs of force which is 3500 joules or a 7.62 / 30-06 round - the typical round fired from an AK-47.
- Geo-Frame Shelter, built by a group taking over 2 Hours
- Nazi Half-Track, Angled armored walls have helped in protecting the crew inside amazingly With the cross section of an “angled” piece of armor is thicker than the same piece of armor up-right.
- M1117 Multi-Role transport, angled panels provide arms fire deflection
- MRAP Mine & IED proof transport Multilayer/Deflection Chassis
- IAV Stryker eight-wheeled, 4-wheel-drive, armored fighting vehicles The high ground clearance, smooth by angled exterior makes it best for survivability without actually being a tank.
- SLAT Tiles - External layer/fence with buffer space that pre-triggers explosive rounds.
The best solution to deal with the impact force while attaining a light weight is - the materials will have to break the typical rules. Use of Non-Newtonian Fluids, a material that hardens when force is applied abruptly, but returns to a soft state when left alone. This material absorbs the brunt of the impact force, while harden composite layers would work in conjunction at breaking the bullet’s jacket & flattening the round to dissipate its mass over a angled surface.
Angled Walls for better protection from small to medium rounds, dissipating the energy of glancing shots. Walls composed of sandwiching 3 staggered layers of Composite Panels and 2 layers of Non-Newtonian Tiles, resulting in a total wall thickness of .75-1.25 inches. Interior made from Prodex High Performing Insulation between 2 layers of Tyvek Vapor Barrier material.
