Book Description
This paper presents the results of an investigation to determine the control-effectiveness characteristics of 30-percent-chord flap-type control surfaces of various spans on a semispan wing-fuselage model. The wing of the mode had 35 degrees of sweepback of the quarter chord, an aspect ratio of 4.0, a taper ratio of 0.6, and an NACA 65A006 airfoil section parallel to the free stream. Lift, rolling moments, and pitching moments were obtained for several angle of attack throughout a small range of control-surface deflections. Most of the data are presented as control-effectiveness parameters which show their variation with Mach number.

Book Description
A New Edition of the Most Effective Text/Reference in the Field! Aerodynamics, Aeronautics, and Flight Mechanics, Second Edition Barnes W. McCormick, Pennsylvania State University 57506-2 When the first edition of Aerodynamics, Aeronautics, and Flight Mechanics was published, it quickly became one of the most important teaching and reference tools in the field. Not only did generations of students learn from it, they continue to use it on the job-the first edition remains one of the most well-thumbed guides you'll find in an airplane company. Now this classic text/reference is available in a bold new edition. All new material and the interweaving of the computer throughout make the Second Edition even more practical and current than before! A New Edition as Complete and Applied as the First Both analytical and applied in nature, Aerodynamics, Aeronautics, and Flight Mechanics presents all necessary derivations to understand basic principles and then applies this material to specific examples. You'll find complete coverage of the full range of topics, from aerodynamics to propulsion to performance to stability and control. Plus, the new Second Edition boasts the same careful integration of concepts that was an acclaimed feature of the previous edition. For example, Chapters 9, 10, and 11 give a fully integrated presentation of static, dynamic, and automatic stability and control. These three chapters form the basis of a complete course on stability and control. New Features You'll Find in the Second Edition * A new chapter on helicopter and V/STOL aircraft- introduces a phase of aerodynamics not covered in most current texts * Even more material than the previous edition, including coverage of stealth airplanes and delta wings * Extensive use of the computer throughout- each chapter now contains several computer exercises * A computer disk with programs written by the author is available

Book Description
This paper presents the results of the investigation of a wing-alone and wing-fuselage configuration employing a wing with the quarter-chord line swept back 45 degrees, with aspect ratio 4, taper ratio 0.3, and an NACA 65A006 airfoil section. Lift, drag, pitching moment, and root bending moment were obtained for these configurations. In addition, effective downwash angles and dynamic-pressure characteristics in the region of a probable tail location were also obtained for these configurations and are presented for a range of tail heights at one tail length. In order to expedite the publishing of these data, only a brief analysis is included.

Book Description
Vortex dynamics is a natural paradigm for the field of chaotic motion and modern dynamical system theory. However, this volume focuses on those aspects of fluid motion that are primarily controlled by the vorticity and are such that the effects of the other fluid properties are secondary.

Book Description
Low-speed aerodynamics is important in the design and operation of aircraft flying at low Mach number, and ground and marine vehicles. This 2001 book offers a modern treatment of the subject, both the theory of inviscid, incompressible, and irrotational aerodynamics and the computational techniques now available to solve complex problems. A unique feature of the text is that the computational approach (from a single vortex element to a three-dimensional panel formulation) is interwoven throughout. Thus, the reader can learn about classical methods of the past, while also learning how to use numerical methods to solve real-world aerodynamic problems. This second edition has a new chapter on the laminar boundary layer (emphasis on the viscous-inviscid coupling), the latest versions of computational techniques, and additional coverage of interaction problems. It includes a systematic treatment of two-dimensional panel methods and a detailed presentation of computational techniques for three-dimensional and unsteady flows. With extensive illustrations and examples, this book will be useful for senior and beginning graduate-level courses, as well as a helpful reference tool for practising engineers.

Book Description
This book deals with the efficient numerical solution of challenging nonlinear problems in science and engineering, both in finite and in infinite dimension. Its focus is on local and global Newton methods for direct problems or Gauss-Newton methods for inverse problems. Lots of numerical illustrations, comparison tables, and exercises make the text useful in computational mathematics classes. At the same time, the book opens many directions for possible future research.
