Here the helicopter model pilot is guided from his first sightseeing flights to full-fledged aerobatics. Whether the goal is to specialize in the championship scene, scale or 3D aerobatics, or simply to pursue high-quality model flying, to realize one's full aeronautical potential, one needs sound guidance such as this. Based on his own extensive experience, Russ Deakin outlines what characteristics a helicopter must meet, what RC equipment is needed, how to set up and maintain the model. He reveals the secrets of modern remote controls and gyros, and describes how to set up or tune both the model and the motor. This is followed by a detailed training program that starts with the flying basics and leads step by step to sightseeing flights, nose hovering and other demanding hovering maneuvers. Finally, you'll dive into the incredibly exciting world of model helicopter aerobatics. Here, it is explained how to safely perform autorotation, fly loops, and succeed in turns. With its easy-to-understand text and more than 180 illustrations, this book is a valuable resource that will guide readers safely and confidently from their first sightseeing flights to any desired discipline of challenging model helicopter flying.
There has been significant interest for designing flight controllers for small-scale unmanned helicopters. Such helicopters preserve all the physical attributes of their full-scale counterparts, being at the same time more agile and dexterous. This book presents a comprehensive and well justified analysis for designing flight controllers for small-scale unmanned helicopters guarantying flight stability and tracking accuracy. The design of the flight controller is a critical and integral part for developing an autonomous helicopter platform. Helicopters are underactuated, highly nonlinear systems with significant dynamic coupling that needs to be considered and accounted for during controller design and implementation. Most reliable mathematical tools for analysis of control systems relate to modern control theory. Modern control techniques are model-based since the controller architecture depends on the dynamic representation of the system to be controlled. Therefore, the flight controller design problem is tightly connected with the helicopter modeling. This book provides a step-by-step methodology for designing, evaluating and implementing efficient flight controllers for small-scale helicopters. Design issues that are analytically covered include: • An illustrative presentation of both linear and nonlinear models of ordinary differential equations representing the helicopter dynamics. A detailed presentation of the helicopter equations of motion is given for the derivation of both model types. In addition, an insightful presentation of the main rotor's mechanism, aerodynamics and dynamics is also provided. Both model types are of low complexity, physically meaningful and capable of encapsulating the dynamic behavior of a large class of small-scale helicopters. • An illustrative and rigorous derivation of mathematical control algorithms based on both the linear and nonlinear representation of the helicopter dynamics. Flight controller designs guarantee that the tracking objectives of the helicopter's inertial position (or velocity) and heading are achieved. Each controller is carefully constructed by considering the small-scale helicopter's physical flight capabilities. Concepts of advanced stability analysis are used to improve the efficiency and reduce the complexity of the flight control system. Controller designs are derived in both continuous time and discrete time covering discretization issues, which emerge from the implementation of the control algorithm using microprocessors. • Presentation of the most powerful, practical and efficient methods for extracting the helicopter model parameters based on input/output responses, collected by the measurement instruments. This topic is of particular importance for real-life implementation of the control algorithms. This book is suitable for students and researches interested in the development and the mathematical derivation of flight controllers for small-scale helicopters. Background knowledge in modern control is required.
First envisioned by Leonardo da Vinci and first deployed in World War II, the helicopter is now a universal icon of modern warfare, a key component of combat planning around the world, and one of the military's most versatile and effective tools. Helicopters: An Illustrated History of Their Impact covers the development of helicopters from a concept in Leonardo daVinci's mind to the first successful machines in the early 1900s to the latest tilt-rotor designs. Time and again, in a story of constant innovation, designers answered the concerns of military planners with more maneuverable, more capable rotorcraft. With expert analysis and specific details of every significant model ever used, Helicopters shows how these once denigrated machines became essential to a variety of missions (reconnaissance, transport, attack, support, evacuation, urban combat, quick strikes behind enemy lines, and more). In addition, the book looks at the impact of rotorcraft beyond the military, including their ever-widening role in emergency medical care, police work, traffic control, agriculture, news reporting, and more.
Over the past eight decades, developments in vertical lift aircraft--both helicopters and vertical/short takeoff and landing (V/STOL) planes--have given the American military unparalleled capabilities on the modern battlefield. The U.S. has led the world in vertical lift technologies with the help of some of the brightest minds in this field--Igor I. Sikorsky, Arthur M. Young, Frank N. Piasecki, Charles H. Kaman and Stanley Hiller, Jr., to name a few--and by having the industrial prowess to make their concepts reality. This book provides a concise historical survey, including technical specifications, drawings, and photographs of every type of helicopter and V/STOL aircraft developed for the U.S. military, from the earliest examples tested in 1941 and 1942, up to the newest prototypes.
