Description

With the advent of new design methodologies in computing power, propulsion systems, materials, and manufacturing processes, there is a tremendous potential to develop revolutionary hypersonic vehicle configurations that meet mission requirements. Traditional analysis and design methods face challenges due to complex interaction of different sub-disciplines such as propulsion, aerodynamics, structures, controls, and heat transfer. Research efforts are required to yield higher-fidelity vehicle configurations that will enable new tactical capabilities for the warfighter.

Our research advances design methodologies by incorporating multi-fidelity physics-based models representing nonlinear behavior of engineering disciplines. Multidisciplinary design optimization is conducted by incorporating cost-effective meta models, sensitivity analysis, uncertainty quantification, and AI tools for facilitating large-scale computational models.
