Book Description
Geometrical, flight, computational fluid dynamics (CFD), and wind-tunnel studies for the F-16XL-1 airplane are summarized over a wide range of test conditions. Details are as follows: (1) For geometry, the upper surface of the airplane and the numerical surface description compare reasonably well. (2) For flight, CFD, and wind-tunnel surface pressures, the comparisons are generally good at low angles of attack at both subsonic and transonic speeds; however, local differences are present. In addition, the shock location at transonic speeds from wind-tunnel presure contours is near the aileron hinge line and generally is in correlative agreement with flight results.

(3) For boundary layers, flight profiles were predicted reasonably well for attached flow and underneath the primary vortex but not for the secondary vortex. Flight data indicate the presence of an interaction of the secondary vortex system and the boundary layer and the boundary-layer measurements show the secondary vortex located more outboard than predicted. (4) Predicted and measured skin friction distributions showed qualitative agreement for a two vortex system. (5) Web-based data-extraction and computational-graphical tools have proven useful in expediting the preceding comparisons. (6) Data fusion has produced insightful results for a variety of visualization-based data sets. Lamar, John E. and Obara, Clifford J. and Fisher, Bruce D. and Fisher, David F.

Book Description
In "Aerodynamic Principles of Flight Vehicles" Argyris Panaras examines the fundamentals of vortices and shock waves, aerodynamic estimation of lift and drag, airfoil theory, boundary layer control, and high-speed, high-temperature flow. Individual chapters address vortices in aerodynamics, transonic and supersonic flows, transonic/supersonic aircraft configurations, and high-supersonic/hypersonic flows, beginning with definitions and historical data, and then describing present-day status and current research challenges. Emphasis is given to flow control, to the evolution of flight vehicle shapes as flight speed has increased, and to discoveries that enabled breakthrough developments in flight. The book: examines why various equations and technologies were developed, explains major contributors in areas such as vortices and aircraft wakes, drag buildup, sonic boom, and shock wave-boundary layer interactions, among others, and helps readers apply concepts from the material to their own projects. Archival and encyclopedic, "Aerodynamic Principles of Flight Vehicles" is a superb reference for aeronautical students and professionals alike. Although most beneficial to readers with a working knowledge of aerodynamics, it is accessible to anyone with an introductory understanding of the field.
