DOWNLOAD EBOOKThe author: Makes minimum use of nondimensional coefficients, and takes great care to define them, and to show their function, their use in the industry and their physical meaning. Contrast this with a typical exposition of the "momentum method," in which the reader is lost in C sub this and C sub that after the first page. Uses the technique of dimensional analysis in explaining the operation of propellers. Explains all the theoretical treatments relevant to the task at hand, shows their relation to one another and gives examples contrasting the procedure and the solutions obtainable with each theory. Each chapter has relevant references listed at the end.In the helicopter section, makes use of propeller theory and gives a clear exposition of the special problems of helicopters. Here again, instead of spending pages expounding the details of theory, he states the results, explains their limitations, and again offers examples. And if that were not enough, he covers numerical procedures for solving problems, which means that this sixty-year-old book is a good basis for digital computer programs or MathCAD worksheets solving the relevant problems. In fact, the computation forms published in the book can easily be converted to spreadsheets.It is true that the book is not a comprehensive or encyclopedic treatment of helicopters. The problem of vibration is not covered, for example. Thus, this text will be useful in preliminary design, but a more detailed text will be needed for more advanced work.

DOWNLOAD EBOOKWritten by an internationally recognized teacher and researcher, this book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft such as tilt rotors and autogiros. The text begins with a unique technical history of helicopter flight, and then covers basic methods of rotor aerodynamic analysis, and related issues associated with the performance of the helicopter and its aerodynamic design. It goes on to cover more advanced topics in helicopter aerodynamics, including airfoil flows, unsteady aerodynamics, dynamic stall, and rotor wakes, and rotor-airframe aerodynamic interactions, with final chapters on autogiros and advanced methods of helicopter aerodynamic analysis. Extensively illustrated throughout, each chapter includes a set of homework problems. Advanced undergraduate and graduate students, practising engineers, and researchers will welcome this thoroughly revised and updated text on rotating-wing aerodynamics.

DOWNLOAD EBOOKClassical aerodynamics is a compulsory study subject for pilots at all levels of experience. Propeller Aerodynamics is a subset of this fascinating subject. Propellers have their unique aerodynamic terminology, forces and handling requirements, knowledge of which all pilots must be aware of to safely handle the aircraft they are flying. Incorrect propeller handling can cause damage to the aircraft and reduce performance efficiency. Most aerodynamic text books only give a brief view of propeller aerodynamics; however this book Propeller Aerodynamics delves more deeply into this subject. The book covers the history and operation of aircraft propellers, prop pitch, thrust, efficiency, aircraft stability, prop forces, constant-speed units and more. This is all essential reading for the pilot progressing to more advanced high-performance aircraft.

DOWNLOAD EBOOKBasic Helicopter Aerodynamics is widely appreciated as an easily accessible, rounded introduction to the first principles of the aerodynamics of helicopter flight. Simon Newman has brought this third edition completely up to date with a full new set of illustrations and imagery. An accompanying website www.wiley.com/go/seddon contains all the calculation files used in the book, problems, solutions, PPT slides and supporting MATLAB® code. Simon Newman addresses the unique considerations applicable to rotor UAVs and MAVs, and coverage of blade dynamics is expanded to include both flapping, lagging and ground resonance. New material is included on blade tip design, flow characteristics surrounding the rotor in forward flight, tail rotors, brown-out, blade sailing and shipborne operations. Concentrating on the well-known Sikorsky configuration of single main rotor with tail rotor, early chapters deal with the aerodynamics of the rotor in hover, vertical flight, forward flight and climb. Analysis of these motions is developed to the stage of obtaining the principal results for thrust, power and associated quantities. Later chapters turn to the characteristics of the overall helicopter, its performance, stability and control, and the important field of aerodynamic research is discussed, with some reference also to aerodynamic design practice. This introductory level treatment to the aerodynamics of helicopter flight will appeal to aircraft design engineers and undergraduate and graduate students in aircraft design, as well as practising engineers looking for an introduction to or refresher course on the subject.

DOWNLOAD EBOOKHelicopters are highly capable and useful rotating-wing aircraft with roles that encompass a variety of civilian and military applications. Their usefulness lies in their unique ability to take off and land vertically, to hover stationary relative to the ground, and to fly forward, backward, or sideways. These unique flying qualities, however, come at a high cost including complex aerodynamic problems, significant vibrations, high levels of noise, and relatively large power requirements compared to fixed-wing aircraft. This book, written by an internationally recognized expert, provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft. Every chapter is extensively illustrated and concludes with a bibliography and homework problems. Advanced undergraduate and graduate students, practising engineers, and researchers will welcome this thorough and up-to-date text on rotating-wing aerodynamics.

DOWNLOAD EBOOKThis volume is an excellent introduction to the aerodynamics of helicopters. Basic Helicopter Aerodynamics provides an account of the first principles in the fluid mechanics and flight dynamics of single-rotor helicopters. The text is intended to provide, in a short volume, an introduction to the theory of rotary-wing aircraft for use by undergraduate and graduate students, while providing a detailed description of the physical phenomena involved. The text assumes that the reader already has some knowledge of differences between the fixed- and rotary-wing aircraft. Many diagrams, drawings, graphs, and representative sets of data augment the text.
