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.

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.

An investigation has been made of the effects of conical wing camber and body indentation according to the supersonic area rule on the aerodynamic wing loading characteristics of a wing-body-tail configuration at transonic speeds. The wing aspect ratio was 3, taper ratio was 0.1, and quarter-chord-line sweepback was 52.5° with 3-percent-thick airfoil sections. The tests were conducted in the Langley 16-foot transonic tunnel at Mach numbers from 0.80 to 1.05 and at angles of attack from 0° to 14°, with Reynolds numbers based on mean aerodynamic chord varying from 7 x 106 to 8 x 106. Conical camber delayed wing-tip stall and reduced the severity of the accompanying longitudinal instability but did not appreciably affect the spanwise load distribution at angles of attack below tip stall. Body indentation reduced to transonic chordwise center-of-pressure travel from about 8 percent to 5 percent of the mean aerodynamic chord.

Aerodynamics has seen many developments due to the growth of scientific computing, which has caused the design cycle time of aerospace vehicles to be heavily reduced. Today computational aerodynamics appears in the preliminary step of a new design, relegating costly, time-consuming wind tunnel testing to the final stages of design. Theoretical and Computational Aerodynamics is aimed to be a comprehensive textbook, covering classical aerodynamic theories and recent applications made possible by computational aerodynamics. It starts with a discussion on lift and drag from an overall dynamical approach, and after stating the governing Navier-Stokes equation, covers potential flows and panel method. Low aspect ratio and delta wings (including vortex breakdown) are also discussed in detail, and after introducing boundary layer theory, computational aerodynamics is covered for DNS and LES. Other topics covered are on flow transition to analyse NLF airfoils, bypass transition, streamwise and cross-flow instability over swept wings, viscous transonic flow over airfoils, low Reynolds number aerodynamics, high lift devices and flow control. Key features: Blends classical theories of incompressible aerodynamics to panel methods Covers lifting surface theories and low aspect ratio wing and wing-body aerodynamics Presents computational aerodynamics from first principles for incompressible and compressible flows Covers unsteady and low Reynolds number aerodynamics Includes an up-to-date account of DNS of airfoil aerodynamics including flow transition for NLF airfoils Contains chapter problems and illustrative examples Accompanied by a website hosting problems and a solution manual Theoretical and Computational Aerodynamics is an ideal textbook for undergraduate and graduate students, and is also aimed to be a useful resource book on aerodynamics for researchers and practitioners in the research labs and the industry.
