Based on the author's decades of industrial experience with Boeing, this book helps students and practicing engineers to gain a greater physical understanding of aerodynamics. Relying on clear physical arguments and examples, Mcleanprovides a much-needed, fresh approach to this sometimes contentious subject without shying away from addressing "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience. Motivated by the belief that engineering practice is enhanced in the long run by a robust understanding of the basics as well as real cause-and-effect relationships that lie behind the theory, he provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations, and building upon the contrasts provided by wrong explanations to strengthen understanding of the right ones.
* Provides a refreshing view of aerodynamics that is based on the author's decades of industrial experience yet is always tied to basic fundamentals.
* Provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations
* Offers new insights to some familiar topics, for example, what the Biot-Savart law really means and why it causes so much confusion, what "Reynolds number" and "incompressible flow" really mean, and a real physical explanation for how an airfoil produces lift.
* Addresses "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience, and omits mathematical details whenever the physical understanding can be conveyed without them.

Doug Mclean, Boeing Commercial Airplanes, USA
Doug McLean is a Boeing Technical Fellow in the Enabling Technology and Research unit within Aerodynamics Engineering at Boeing Commercial Airplanes. He received a BA in physics from the University of California at Riverside in 1965 and a PhD in aeronautical engineering from Princeton University in 1970. He joined the Boeing Commercial Airplane Group in 1974 and has worked there ever since on a range of problems, both computational and experimental, in the areas of viscous flow, drag reduction, and aerodynamic design. Computer programs he developed for the calculation of three-dimensional boundary layers and swept shock/boundary-layer interactions were in use by wing-design groups at Boeing for many years.
