PDF-(BOOK)-Helicopter Theory (Dover Books on Aeronautical Engineering)

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 screwtype propeller In the late nineteenth 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 technologyWhile 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 moreWayne Johnson has worked for the US 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 verticalflight aircraft.

Most useful in working with wing sections and methods for using section data to predict wing characteristics . . . much detailed geometric and aerodynamic data. — Mechanical EngineeringThe first edition of this work has been corrected and republished in answer to the continuing demand for a concise compilation of the subsonic aerodynamics characteristics of modern NASA wing sections together with a description of their geometry and associated theory. These wing sections, or their derivatives, continue to be the ones most commonly used for airplanes designed for both subsonic and supersonic speeds, and for helicopter rotor blades, propeller blades, and high performance fans.Intended to be primarily a reference work for engineers and students, the book devotes over 300 pages to theoretical and experimental considerations. The theoretical treatment progresses from elementary considerations to methods used for the design of NACA low-drag airfoils. Methods and data are presented for using wingsection data to predict wing characteristics, and judiciously selected plots and cross-plots of experimental data are presented for readily useful correlation of certain simplifying assumptions made in the analyses. The chapters on theory of thin wings and airfoils are particularly valuable, as is the complete summary of the NACA\'s experimental observations and system of constructing families of airfoils. Mathematics has been kept to a minimum, but it is assumed that the reader has a knowledge of differential and integral calculus, and elementary mechanics.The appendix of over 350 pages contains these tables: Basic Thickness Forms, Mean Lines, Airfoil Ordinates, and Aerodynamic Characteristics of Wing Sections. This excellent, innovative reference offers a wealth of useful information and a solid background in the fundamentals of aerodynamics. Fluid mechanics, constant density inviscid flow, singular perturbation problems, viscosity, thin-wing and slender body theories, drag minimalization, and other essentials are addressed in a lively, literate manner and accompanied by diagrams. Perhaps the most balanced, well-written account of fundamental fluid dynamics ever published. Mises\' classic avoids the formidable mathematical structure of fluid dynamics, while conveying — by often unorthodox methods — a full understanding of the physical phenomena and mathematical concepts of aeronautical engineering. An outstanding textbook. — Scientific, Medical and Technical Books. Teaching text developed by U.S. Air Force Academy and designed as a first course emphasizes the universal variable formulation. Develops the basic two-body and n-body equations of motion orbit determination classical orbital elements, coordinate transformations differential correction more. Includes specialized applications to lunar and interplanetary flight, example problems, exercises. 1971 edition. Charming, reader-friendly chronicle by a famous pioneer in aerodynamic research traces the development of dynamic flight from the time of Newton through the 20th century. It recounts struggles of engineers and physicists with problems associated with lift, drag, stability, aeroelasticity, and the sound barrier. 72 figures. 1957 edition. Written by one of the leading aerospace educators of our time, each sentence is packed with information. An outstanding book. — Private PilotIlluminated throughout by new twists in explaining familiar concepts, helpful examples and intriguing by-the-ways. A fine book. — Canadian Aeronautics and Space JournalThis classic by a Stanford University educator and a pioneer of aerospace engineering introduces the complex process of designing atmospheric flight vehicles. An exploration of virtually every important subject in the fields of subsonic, transonic, supersonic, and hypersonic aerodynamics and dynamics, the text demonstrates how these topics interface and how they complement one another in atmospheric flight vehicle design. The mathematically rigorous treatment is geared toward graduate-level students, and it also serves as an excellent reference. Problems at the end of each chapter encourage further investigation of the text\'s material, the study of fresh ideas, and the exploration of new areas. Pointing a satellite in the right direction requires an extremely complex system — one that describes the satellite\'s orientation and at the same time predicts and either uses or neutralizes external influences.From its roots in classical mechanics and reliance on stability theory to the evolution of practical stabilization ideas, Spacecraft Attitude Dynamics offers comprehensive coverage of environmental torques encountered in space energy dissipation and its effects on the attitude stability of spinning bodies motion equation for four archetypical systems derived and used repeatedly throughout the text orientation parameters (not limited to Euler angles) illustrations of key concepts with on-orbit flight data and typical engineering hardware, with examples of the implementation of dynamic ideas.Suitable as a text for advanced undergraduates and graduate students, this unified treatment is also a valuable reference for professional engineers studying the analysis and application of modern spacecraft attitude dynamics. The sole prerequisites are a fundamental knowledge of vector dynamics and matrix algebra. Over 250 diagrams appear throughout the text, along with extensive problem sets at the end of each chapter, 350 references (cited, interpreted, and placed in perspective to reinforce the material), and two helpful appendixes. Geared toward advanced undergraduates and graduate students, this outstanding text surveys aeroelastic problems, their historical background, basic physical concepts, and the principles of analysis. It has also proven highly useful to designers and engineers concerned with flutter, structural dynamics, flight loads, and related subjects.
