AFRC Program Manager Al Bowers and Langley Research Center senior research engineer Sue Grafton previously worked together on such projects as the highly successful F-18 High Alpha Research Vehicle, or HARV. During the nine-year project that investigated a new flight control system at high angles of attack, the two Centers compared flight and wind tunnel data. The Preliminary Research Aerodynamic Design to Lower Drag, or PRANDTL-d, was an opportunity to partner again.
