Summary
Karagozian & Case, Inc. (K&C) and Georgia Tech University (GT) collaborated to conduct a two-year Phase II Small Business Innovative Research (SBIR) study aimed at developing and demonstrating feasibility of a low- cost, re-usable, pseudo-static testing apparatus as the Rigid-Body Off-Axis Ordnance Shock and Tail-slap Environment Replicator (ROOSTER) requested in Air Force Topic AF151-104. The test apparatus will be capable of generating accelerations over 10,000 g and sustained durations over 5 ms, along at least two axes, to sub-scale non-inventory warheads or strategically-designed warhead surrogate bodies that replicate the complex deceleration environment experienced by ordnance during penetration into a variety of targets. To meet the challenging requirements outlined in the solicitation, the team has conceived a simple, controllable, and scalable test apparatus that we propose to develop and demonstrate feasibility. This will be done using K&C’s validated first-principle computational models, some limited proof-of-concept testing, and through fabricating a subscale bench-top prototype of the test apparatus.
