FUNDAMENTAL AERONAUTICS - THE AERONAUTICAL SCIENCES PROJECT
A computer image of a fundamental large eddy simulation analysis of flow separation following a backward-facing step. The Aeronautical Sciences Project is developing computer-based tools and models as well as scientific knowledge that will lead to significant advances in our ability to understand and predict flight performance for a wide variety of air vehicles.

Examples of this research include the development of new computational tools that are used to predict the flow around vehicles. Another area of research that is of benefit to a number of vehicle types is improving the understanding and development of new types of strong and lightweight materials that are important for aviation.

For questions regarding the Aeronautical Sciences Project, contact Jim Heidmann.



The Aeronautical Sciences Project is organized around Research Themes that articulate the longer-term, important areas of research necessary to advance the state of the art for a flight regime or discipline. Within the context of the themes, nearer-term technological capabilities necessary to help overcome national challenges in air transportation are defined as Technical Challenges (TCs).

Research Themes and Technical Challenges (TCs)
Theme TC Title TC Description
Revolutionary Computational Aerosciences Physics-Based Turbulence Models and Simulations Identify and down-select critical turbulence, transition, and numerical method technologies for 40% reduction in predictive error against standard test cases for turbulent separated flows, evolution of free shear flows and shock-boundary layer interactions on state-of-the-art high performance computing hardware
Structures and Materials High Temperature Materials for Turbine Engines Develop high-temperature materials for turbine engines that enable a 6% reduction in fuel burn for commercial aircraft, compared to current SOA materials
