Rapid design of hypersonic vehicles research at the George H.W. Bush Combat Development Complex pursues methods to enhance the assured delivery of lethal payloads, including more precise delivery over an extended range through a more comprehensive understanding of flight sciences.
The objective of this project is rapid physics-based modeling for confident (precision and survivability) aerothermodynamic designs of hypersonic flight systems.
Texas A&M University faculty are working on two main types of computerized aerodynamic simulations. One will predict when smooth, stable air transitions into turbulent, unstable air. Another will predict how turbulent air impacts the heat loads pressing against the moving objects.
