High-Fidelity Design Tools for Electromagnetic Scattering Over Hypersonic Vehicles

Corvid Technologies and the University of Colorado Nonequilibrium Gas and Plasma Dynamics Laboratory propose a coupled framework that combines high-fidelity, unsteady computational fluid dynamics (CFD), finite rate gas species chemistry, gas-surface interaction, surface heat transfer, in-depth heat conduction, enclosure radiation heat transfer, and electromagnetic signature modeling. In developing the framework, Corvid will draw on extensive high-fidelity modeling and simulation experience in concert with the University of Colorado’s world-leading expertise in nonequilibrium gas chemistry and plasma physics. Corvid will develop the proposed coupling framework in the Phase I effort by leveraging in-house expertise, software development teams, computational resources including an on-site high performance computing cluster with 50,000 central processing units (CPUs), and additional expertise provided by the University of Colorado. By the end of Phase I, Corvid will demonstrate the framework’s ability to simulate aerothermal effects and electromagnetic signatures from benchmark cases taken from the research literature. In Phase II, Corvid will pursue means to achieve higher fidelity with the coupling framework as well as optimize its computational efficiency; validation will be also performed by comparing model results to experimental data for a variety of applications. In Phase III, Corvid will commercialize the coupling framework by producing a licensable software package.
