Project Title: Digital Wind
The interplay between computational fluid dynamics (CFD) and experimental fluid dynamics (EFD) has been an important topic to the aeronautics community for over 40 years. Conversely, the wind tunnel has provided precision measurements essential to the calibration/validation of CFD models. Although both tools have matured significantly, CFD and EFD are narrowly confined to addressing the aerodynamics of a system under development and consequently are not significantly impacting the cycle time and total ownership costs of developing, fielding, and sustaining an aeronautical system to the extent possible. However, a new paradigm focused on integrating computational and experimental knowledge is based on a more expansive inclusion of physics-based modeling and physical measurements to include not only the aerodynamics but structures, propulsion, control systems, avionics, etc. Referred to as the Digital Thread/Digital Twin, this new paradigm is enabled, not only by advances in computational sciences, but new directions in policies and practices supportive of better use of government technical expertise and insight in collaboration with industry.
