Karagozian & Case, Inc. (K&C) and the Georgia Institute of Technology (Georgia Tech) will develop a re-usable, cost-effective, and accurate dynamic characterization methodology capable of measuring the dynamic material properties of various materials of interest under very high strain rates. Materials property data for various ductile materials (e.g., steel and aluminum) are required as input to first-principles computation codes. First principles codes, like ALE3D, DYNA3D (and PARADYN), ABAQUS, and LS DYNA, for example, are used to assess the response of various structures and components subjected to energetic events or high-velocity impacts, and the accuracy of predictions obtained from them are highly dependent on the accuracy of their material models and the data used to calibrate them.

The flight and environment conditions encountered by vehicles operating in the Mach 10 to 20+, or high hypersonic, regime are complex and difficult to model. Under such conditions, ablating heat shield material is entrained in the flow in the form of gases and particulates and reactive chemistry between atmospheric and ablating species creates a non-local thermodynamic equilibrium (NLTE) environment.The flow may ionize and form a plasma sheath around the vehicle and the boundary layer transitions from laminar to turbulent. All these effects have a strong impact on the vehicle electro-optic/infrared and radar signatures, interfering with detection, tracking, targeting, and aim-point selection.Spectral Sciences, Inc. proposes to develop innovative hypersonic flowfield signature simulation software.The proposed software will be interfaced to existing, high fidelity flow solvers to enable a practical and accurate end-to-end simulation capability for hypersonic signatures.The proposed approach is based on several innovations which will enable 3D, turbulent simulations to accurately predict hypersonic threat signatures.Approved for Public Release | 18-MDA-9710 (6 Jul 18)
