The Navier-Stokes equation adequately describe aerodynamic flows at standard atmospheric temperatures and pressures. If we could efficiently solve these equations there would be no need for experimental tests to design flight vehicles or other aerodynamic devices. Although we have made much progress toward their solution, including complex unsteady two-dimensional and steady three-dimensional separated flows and have recently made some dramatic improvments in developing numerical methods, the calculation of flow fields past complete aircraft configurations at flight Reynolds numbers are far beyond our reach, perhaps as long as a decade away. They await substantial progress in devising accurate and efficient numerical methods, in understanding and modeling the physics of turbulence, and in developing reliable and powerful computer hardware.
