The cancellation of the CF-105 Arrow in 1959 holds such a grip on the imagination of Canadians that earlier developments in defence procurement remain in the shadows. Randall Wakelam corrects this oversight � and offers fresh insight into the AVRO saga and contemporary procurement issues � by detailing the complexities Canada's air force faced in buying fighter aircraft and by showing how the RCAF grew by leaps and bounds. Wakelam shows that cabinet members, chiefs of staff, and air marshals were forced to negotiate competing pressures to arm the air force, please allies, and save money. Their decisions resulted in the CF-100 Canuck and the F-86 Sabre, Canada's front-line defensive aircraft in the coldest years of the Cold War. Although historians assume that the Arrow arrived on the heels of these successes, Wakelam reveals that neither the air force nor the government believed AVRO could manufacture even the CF-100 on budget.

Perhaps the only full publication to present a unified and straightforward introduction to the design and analysis of automatic control systems for both atmospheric and space flight vehicles, Automatic Control of Atmospheric and Space Flight Vehicles is intended to be a textbook for senior undergraduate and graduate students in aerospace engineering/aeronautics and astronautics departments. Covering basic control theory and design concepts, the material in the book has been specifically developed for a modern course on flight control systems, where the artificial distinction between aircraft, rockets, and spacecraft is removed. A wide variety of flight control topics are presented in a concise and easy-to-read—yet rigorous—manner. The book highlights an understanding of relevant flight dynamic principles required for designing a flight control system, placing specific emphasis on a wealth of realistic examples and exercises that require programming. A particularly appealing feature of the text is the ready and extensive use of MATLAB®/Simulink® codes in the many solved examples illustrating flight control design and analysis; these examples give the reader hands-on experience with practical problems and make the book an even more useful and illuminating tool. For convenience, all the codes used can be downloaded from the author's and publisher’s websites. Moreover, selected exercise solutions are provided in the text, and a full solutions manual is available to instructors online. The coverage of flight control topics in the book is fundamental rather than exhaustive, with a greater emphasis on single-variable control for a strong understanding of the relevant concepts. The work may therefore be used for a first course on flight control systems. However, it also covers some advanced topics—such as linear optimal control, nonlinear orbit plane control, and two-point boundary value problem solution for de-orbiting spacecraft—imparting a flavor of the variety found in automatic flight control, and will be of interest to experienced researchers and practitioners in aerospace and control engineering.

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 researchers interested in the development and the mathematical derivation of flight controllers for small-scale helicopters. Background knowledge in modern control is required.
