Amid a welter of topics on the aeronautical engineering curriculum—hypersonic fluid mechanics, heat transfer, nonequilibrium phenomena, etc. —this concise text stands out as a rigorous, classroom-tested treatment of classical aerodynamic theory— indispensable background for aeronautical engineers and foundation of current and future research. The present volume is also unique for its recognition of matched asymptotic expansions as a unifying framework for introducing boundary-value problems of external flow over thin wings and bodies. In addition, the book fully acknowledges the important role of high-speed computers in aerodynamics.
