Like previous editions, this text has retained it's excellent coverage of basic concepts and broad coverage of the major aspects of aerodynamics. Numerical techniques are described for computing invicid incompressible flow about airfoils and finite wings. Plus, the design of devices and aircraft components that were constructed from theoretical considerations are shown so readers can see the realistic applications of mathematical analyses.
