Written 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.

This book is developed to serve as a concise text for a course on helicopter aerodynamics at the introductory level. It introduces to the rotary-wing aerodynamics, with applications to helicopters, and application of the relevant principles to the aerodynamic design of a helicopter rotor and its blades. The basic aim of this book is to make a complete text covering both the basic and applied aspects of theory of rotary wing flying machine for students, engineers, and applied physicists. The philosophy followed in this book is that the subject of helicopter aerodynamics is covered combining the theoretical analysis, physical features and the application aspects. Considerable number of solved examples and exercise problems with answers are coined for this book. This book will cater to the requirement of numerical problems on helicopter flight performance, which is required for the students of aeronautical/aerospace engineering.. SALIENT FEATURES • To provide an introductory treatment of the aerodynamic theory of rotary-wing aircraft • To study the fundamentals of rotor aerodynamics for rotorcraft in hovering flight, axial flight, and forward flight modes • To perform blade element analysis, investigate rotating blade motion, and quantify basic helicopter performance

This book gives an account from first principles of the aerodynamics of helicopter flight, 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 but the lengthy mathematical treatment of some textbooks is avoided. 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. The Second Edition has been revised to illustrate more fully the various features of rotor aerodynamics and helicopter design. The helicopter is unique in its linking of the aerodynamic and mechanical features and a full appreciation of these air vehicles can only be achieved by understanding these interactions. Many of the extra figures illustrate the diversity in the design and operation of a helicopter and these differences are highlighted in the text. The book is aimed initially at the needs of undergraduates and postgraduates. However, because of its conciseness, it is likely to prove useful also to workers at any stage, as a background to short industrial courses or for anyone needing a refresher course in the basics of the subject.

Trade Paperback + PDF eBook "bundle" version: Trade paperback book comes with code to download the eBook from ASA's website. This comprehensive textbook explains the aerodynamics of helicopter flight as well as helicopter maneuvers, going beyond the strictly "how-to" type of aviation manual. Helicopter pilots need to thoroughly understand the consequences of their actions and base them upon sound technical knowledge; this textbook explains why the helicopter flies and even more importantly, why it sometimes does not. Beginning with aerodynamics, each step of the process is fully illustrated and thoroughly explained--from the physics of advanced operations to helicopter design and performance--providing helicopter pilots with a solid foundation upon which to base their in-flight decisions. Containing discussions on the NOTAR (no tail rotor) system, strakes, principles of airspeed and high-altitude operations, operations on sloping surfaces, and sling operations, this revised edition also includes the latest procedures Federal Aviation Administration.

A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics covers much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics include many of the key performance attributes and the often-encountered problems in rotorcraft designs. This comprehensive book presents, in depth, what engineers need to know about modelling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behaviour. The first third of the book is an introduction to rotorcraft aerodynamics, blade motion, and performance. The remainder of the book covers advanced topics in rotary wing aerodynamics and dynamics.
