DTIC ADA127794: High Angle-of-Attack Aerodynamics

The Lecture Series begins with a review of three-dimensional flows on simple components including separation and reattachment. Particular emphasis is placed on the vortical flows which characterize the high-alpha regime. Vortex breakdown, vortex control, and the effect of compressibility on these three- dimensional flows as well as the present and future capabilities of computational techniques are discussed. These fundamental lectures are supplemented by a description of the techniques currently employed by combat aircraft and missile design groups. Finally, the important field of unsteady aerodynamics and its implications for the high-alpha case is reviewed.
