Starting from a basic knowledge of mathematics and mechanicsgained in standard foundation classes, Theory of Lift:Introductory Computational Aerodynamics in MATLAB/Octave takesthe reader conceptually through from the fundamental mechanics oflift to the stage of actually being able to make practicalcalculations and predictions of the coefficient of lift forrealistic wing profile and planform geometries. The classical framework and methods of aerodynamics are coveredin detail and the reader is shown how they may be used to developsimple yet powerful MATLAB or Octave programs that accuratelypredict and visualise the dynamics of real wing shapes, usinglumped vortex, panel, and vortex lattice methods. This book contains all the mathematical development and formulaerequired in standard incompressible aerodynamics as well as dozensof small but complete working programs which can be put to useimmediately using either the popular MATLAB or free Octavecomputional modelling packages. Key features: Synthesizes the classical foundations of aerodynamics withhands-on computation, emphasizing interactivity andvisualization. Includes complete source code for all programs, all listingshaving been tested for compatibility with both MATLAB andOctave. Companion website (ahref="http://www.wiley.com/go/mcbain"www.wiley.com/go/mcbain/a)hosting codes and solutions. Theory of Lift: Introductory Computational Aerodynamics inMATLAB/Octave is an introductory text for graduate and seniorundergraduate students on aeronautical and aerospace engineeringcourses and also forms a valuable reference for engineers anddesigners.

The history of the helicopter may be traced back to the Chinese flying top (c. 400 BC) and to the work of Leonardo da Vinci, who sketched designs for a vertical flight machine utilizing a screw-type propeller. In the late 19th-century, Thomas Edison experimented with helicopter models, realizing that no such machine would be able to fly until the development of a sufficiently lightweight engine. When the internal combustion gasoline engine came on the scene around 1900, the stage was set for the real development of helicopter technology. While this text provides a concise history of helicopter development, its true purpose is to provide the engineering analysis required to design a highly successful rotorcraft. Toward that end the book offers thorough, comprehensive coverage of the theory of helicopter flight: the elements of vertical flight, forward flight, performance, design, mathematics of rotating systems, rotary wing dynamics and aerodynamics, aeroelasticity, stability and control, stall, noise and more. Wayne Johnson has worked for the U.S. Army and NASA at the Ames Research Center in California. Through his company Johnson Aeronautics, he is engaged in the development of software that is used throughout the world for the analysis of rotorcraft. In this book, Dr. Johnson has compiled a monumental resource that is essential reading for any student or aeronautical engineer interested in the design and development of vertical-flight aircraft.

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

Much-needed, fresh approach that brings a greater insight intothe physical understanding of aerodynamics Based on the author’s decades of industrial experiencewith Boeing, this book helps students and practicing engineers togain a greater physical understanding of aerodynamics. Relying onclear physical arguments and examples, Mclean provides amuch-needed, fresh approach to this sometimes contentious subjectwithout shying away from addressing "real" aerodynamic situationsas opposed to the oversimplified ones frequently used formathematical convenience. Motivated by the belief that engineeringpractice is enhanced in the long run by a robust understanding ofthe basics as well as real cause-and-effect relationships that liebehind the theory, he provides intuitive physical interpretationsand explanations, debunking commonly-held misconceptions andmisinterpretations, and building upon the contrasts provided bywrong explanations to strengthen understanding of the rightones. Provides a refreshing view of aerodynamics that is based on theauthor’s decades of industrial experience yet is alwaystied to basic fundamentals. Provides intuitive physical interpretations and explanations,debunking commonly-held misconceptions and misinterpretations Offers new insights to some familiar topics, for example, whatthe Biot-Savart law really means and why it causes so muchconfusion, what “Reynolds number” and“incompressible flow” really mean, and a real physicalexplanation for how an airfoil produces lift. Addresses "real" aerodynamic situations as opposed to theoversimplified ones frequently used for mathematical convenience,and omits mathematical details whenever the physical understandingcan be conveyed without them.

All technologies differ from one another. They are as varied as humanity's interaction with the physical world. Even people attempting to do the same thing produce multiple technologies. For example, John H. White discovered more than l 1000 patents in the 19th century for locomotive smokestacks. Yet all technologies are processes by which humans seek to control their physical environment and bend nature to their purposes. All technologies are alike. The tension between likeness and difference runs through this collection of papers. All focus on atmospheric flight, a twentieth-century phenomenon. But they approach the topic from different disciplinary perspectives. They ask disparate questions. And they work from distinct agendas. Collectively they help to explain what is different about aviation - how it differs from other technologies and how flight itself has varied from one time and place to another. The importance of this topic is manifest. Flight is one of the defining technologies of the twentieth century. Jay David Bolter argues in Turing's Man that certain technologies in certain ages have had the power not only to transform society but also to shape the way in which people understand their relationship with the physical world. "A defining technology," says Bolter, "resembles a magnifying glass, which collects and focuses seemingly disparate ideas in a culture into one bright, sometimes piercing ray." 2 Flight has done that for the twentieth century.

Originator of many of the theories used in modern wing design, Robert T. Jones surveys the aerodynamics of wings from the early theories of lift to modern theoretical developments. This work covers the behavior of wings at both low and high speeds, including the range from very low Reynolds numbers to the determination of minimum drag at supersonic speed. Emphasizing analytical techniques, Wing Theory provides invaluable physical principles and insights for advanced students, professors, and aeronautical engineers, as well as for scientists involved in computational approaches to the subject. This book is based on over forty years of theoretical and practical work performed by the author and other leading researchers in the field of aerodynamics. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This thesis analyzes aerodynamic forces in viscous and compressible external flows. It is unique, as the force theories discussed apply to fully viscous and compressible Navier-Stokes external flows, allowing them to be readily combined with computational fluid dynamics to form a profound basis of modern aerodynamics. This thesis makes three fundamental contributions to theoretical aerodynamics, presenting: (1) a universal far-field zonal structure that determines how disturbance flow quantities decay dynamically to the state of rest at infinity; (2) a universal and exact total-force formula for steady flow and its far-field asymptotics; and (3) a general near-field theory for the detailed diagnosis of all physical constituents of aerodynamic force and moment.
