Good flying qualities are vital for ensuring that mission performance is achievable with safety and, in the first edition of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented. In this second edition, the author complements this with a new chapter on degraded flying qualities, drawing examples from flight in poor visibility, failure of control functions and encounters with severe atmospheric disturbances. Fully embracing the consequences of degraded flying qualities during the design phase will contribute positively to safety. The accurate prediction and assessment of flying qualities draws on modelling and simulation discipline on the one hand and testing methodologies on the other. Checking predictions in flight requires clearly defined 'mission-task-elements', derived from missions with realistic performance requirements. High fidelity simulations also form the basis (or the design of stability and control augmentation systems, essential for conferring level one flying qualities. The integrated description of flight dynamic modelling, simulation and flying qualities forms the subject of this book, which will be of interest to engineers in research laboratories and manufacturing industry, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.

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.

The pilot's guide to aeronautics and the complex forces of flight Flight Theory and Aerodynamics is the essential pilot's guide to the physics of flight, designed specifically for those with limited engineering experience. From the basics of forces and vectors to craft-specific applications, this book explains the mechanics behind the pilot's everyday operational tasks. The discussion focuses on the concepts themselves, using only enough algebra and trigonometry to illustrate key concepts without getting bogged down in complex calculations, and then delves into the specific applications for jets, propeller crafts, and helicopters. This updated third edition includes new chapters on Flight Environment, Aircraft Structures, and UAS-UAV Flight Theory, with updated craft examples, component photos, and diagrams throughout. FAA-aligned questions and regulatory references help reinforce important concepts, and additional worked problems provide clarification on complex topics. Modern flight control systems are becoming more complex and more varied between aircrafts, making it essential for pilots to understand the aerodynamics of flight before they ever step into a cockpit. This book provides clear explanations and flight-specific examples of the physics every pilot must know. Review the basic physics of flight Understand the applications to specific types of aircraft Learn why takeoff and landing entail special considerations Examine the force concepts behind stability and control As a pilot, your job is to balance the effects of design, weight, load factors, and gravity during flight maneuvers, stalls, high- or low-speed flight, takeoff and landing, and more. As aircraft grow more complex and the controls become more involved, an intuitive grasp of the physics of flight is your most valuable tool for operational safety. Flight Theory and Aerodynamics is the essential resource every pilot needs for a clear understanding of the forces they control.

Sometimes you do everything right, but it just isnÕt your day. A part fails and your helicopter comes apart in flight, or, another aircraft runs into you and the pieces of both fall to the ground below, or the enemy gunner pulls the trigger at just the right moment and his rounds find your aircraft in exactly the right spot to take it out of the sky. Whichever way it happens, it wasnÕt your day. Which is why, after 24 years and over 5,000 flight hours with four armed services, Major Robert Curtis was so surprised at being alive when he passed his retirement physical. Starting with enlisting in the Army to fly helicopters during Vietnam, and continuing on through service with the National Guard, Marine Corps and Royal Navy, he flew eight different helicoptersÑfrom the wooden-bladed OH-13E, through the Chinook, SeaKnight and SeaKing, in war and peace around the world. During that time over 50 of his friends died in crashes, both in combat and in accidents, but somehow his skill, and not an inconsiderable amount of luck and superstition, saw him through. His flying career began with a misbegotten strategy for beating the draft by enlisting. With the Vietnam War raging full blast in 1968 the draft was inevitable, so he wanted to at least get some small measure of control of his future. Although he had no thought of flying when he walked into the recruiting office, he walked out signed up to be a helicopter pilot. What he did not know was that 43% of all the aircraft sent to Vietnam were destroyed in combat or accidents. Soon he was in the thick of the war, flying Chinooks with the 101st Airborne. After Vietnam he left the Army, but kept flying in the National Guard while going to college. He was accepted at two law schools, but flying is addictive, so he instead enlisted in the USMC to fly some more. Over the next 17 years he would fly around the world off US and British ships from Egypt to Norway and all points in between. His engaging story will be a delight to all aviation enthusiasts.
