- Title
Computational Fluid Dynamics to Flight: Recent Success Stories of X-Plane Design to Flight Test at the NASA Dryden Flight Research Center.

Cosentino, Gary B.
- Abstract
Several examples from the past decade of success stories involving the design and flight test of three true X-planes are described: in particular, X-plane design techniques that relied heavily upon computational fluid dynamics (CFD). Three specific examples chosen from the author's personal experience are presented: the X-36 Tailless Fighter Agility Research Aircraft, the X- 45A Unmanned Combat Air Vehicle, and, most recently, the X-48B Blended Wing Body Demonstrator Aircraft. An overview is presented of the uses of CFD analysis, comparisons and contrasts with wind tunnel testing, and information derived from the CFD analysis that directly related to successful flight test. Some lessons learned on the proper application, and misapplication, of CFD are illustrated. Finally, some highlights of the flight-test results of the three example X-planes are presented.
