Much-needed, fresh approach that brings a greater insight into the physical understanding of aerodynamics 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, Mclean provides 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.

This outstanding thesis characterises the aerodynamic flow around a container freight train; investigating how changing container loading configurations affect the magnitude of aerodynamic forces measured on a container. 1/25th scale moving-model freight train experiments were carried out at the University of Birmingham’s TRAIN rig facility to investigate slipstream velocities and static pressure, as well as measuring, using a specifically designed on-board pressure monitoring system, the aerodynamic loads on containers. Results were compared with full scale data and assessed in terms European standards for trackside worker and passenger safety limits. Rail vehicle aerodynamic studies have tended to previously focus on high speed passenger trains in line with increases in train speed. The research presented within this thesis highlights the issues associated with the aerodynamic development around a freight train, providing the foundations for further research and a basis from which to develop international safety standards in relation to freight, as well as high speed trains.

From the Foreword: 'John Anderson's book represents a milestone in aviation literature. For the first time aviation enthusiasts - both specialists and popular readers alike - possess an authoritative history of aerodynamic theory. Not only is this study authoritative, it is also highly readable and linked to the actual (and more familiar) story of how the airplane evolved. The book touches on all the major theorists and their contributions and, most important, the historical context in which they worked to move the science of aerodynamics forward.' Von Hardesty, Smithsonian Institution From the reviews: 'Something of the unexpected quality of this book can be inferred from its full title A History of Aerodynamics and Its Impact on Flying Machines. Pilots tend to suppose that the science of aerodynamics began empirically, somewhere around the time of Lilienthal and the Wrights, and that aerodynamics and manned flight are roughly coeval. It is therefore surprising to come upon a photograph of the Wright Flyer as late as page 242 of the 478-page volume.' Peter Garrison, Flying 'This book successfully straddles the boundary that separates a text book from a history book. It is of equal interest to both the aerodynamicist and the layman. The textual balance achieved by the author has resulted in a book that is enjoyable and educational.' Earl See, American Aviation Historical Society Newsletter

Annotation This textbook and its six supporting computer programs provide theoretical modeling of the aerodynamic characteristics of wings and bodies at low Mach numbers. The approach presented directly helps engineering students improve problem-solving skills by teaching them to discern the necessary steps associated with solving analytical problems. The book also presents a justification and rationale for validating end results that leave the student with an understanding of the answer. The text differs from others by providing interactive computer programs that allow the student to conduct trade studies. It provides case-specific software that permits the student to do considerably more characteristic analysis of user-selected wings and bodies than is possible with other introductory textbooks. In addition, the algorithms are capable of working problems at a level well beyond those typically solved by hand in other textbooks. This approach allows students to determine easily the effects of modifying parameters and geometry. Another benefit of using this textbook is the understanding students gain of the capabilities of large industrial codes.
