Advanced Light Armor for Helicopter and Other Applications
Phone: (215) 723-8588
A concept involves use of hard spheres embedded in a semi-viscous polymer and the protection mechanism is based on: (a) tipping geometry between projectile and armor spheres, (b) the hardness of the spheres and, (c) further energy absorption by the elastromeric medium. A program is proposed which involves the use of conventional (sphere) materials such s steel, (in order to prove the concept) and advanced lower density ceramics such as A12)3, B4C and TiB2 which will be evaluated in conjunction with rubber type matrices such as silicone, polyurethane, DPR and polysulfide in order to maximize the effectiveness of a light weight option. A program based on materials formulation and subsequent testing (and evaluation) is proposed in an effort to develop armor materials which can provide significant weight reduction over conventional armor materials. Hydrocode Analysis (for further prediction) will also be performed; this task will be supported by experimental inputs on failure/protectin mechanisms.
