The helicopter, in spite of what may be said, remains a strange machine retaining for the « man in the street » (and sometimes even the initiated) a somewhat magic and mysterious aspect. In this pages, our wish is to tear off this veil of mystery. But, it is to be well understood that in a few pages it is not possible to explain everything. Therefore we have made a choice dictated by pratictal consideration. Let us hope it is the right one !
Basic 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.
Monumental engineering text covers vertical flight, forward flight, performance, mathematics of rotating systems, rotary wing dynamics and aerodynamics, aeroelasticity, stability and control, stall, noise, and more. 189 illustrations. 1980 edition.
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 includesthe latest procedures Federal Aviation Administration.
Helicopters 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.
Helicopter Dynamics Introduced in an Organized and Systematic MannerA result of lecture notes for a graduate-level introductory course as well as the culmination of a series of lectures given to designers, engineers, operators, users, and researchers, Fundamentals of Helicopter Dynamics provides a fundamental understanding and a thorough overview o
The unique design problems which helicopters produce are many and complex. Through practical examples and illustrated case studies, supported by all the relevant theory, this primer text provides an accessible introduction which guides the reader through the theory, design, construction and operation of helicopters. Fundamental performance and control equations are developed, from which the book explores the rotor aerodynamic and dynamic characteristics of helicopters. Example calculations and performance predictions, reflecting current practice, show how to assess the feasibility of a design.* Tackles the theory, design, construction and operation of helicopters* Illustrated with many practical examples and case studies* Provides the fundamental equations describing performance and dynamic behaviour
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
