Book Description
A set of longitudinal stability derivatives for elastic airplanes is defined from fundamental principles allowing perturbations in forward speed. Application of these derivatives to longitudinal stability analysis by use of approximate expressions for static stability and control parameters as well as the dynamic equations of motion is illustrated. One commonly used alternative formulation for elastic airplanes is shown to yield significant inaccuracies because of inappropriate interpretation of inertial effects.

Book Description
"In this part, exhaustive coverage is provided of the methods for analysis and synthesis of automatic flight control systems using classical control theory. This widely used book has been updated with the latest software methods. Throughout this text, the practical (design) applications of the theory are stressed with many examples and illustrations. Aircraft stability and control characteristics are all heavily regulated by civil as well as by military airworthiness authorities for safety reasons. The role of the these safety regulations in the application of the theory is therefore stressed throughout. Airplane Flight Dynamics & Automatic Flight Controls, Part II, is an essential reference for all aeronautical engineers working in the area of stability and control, regardless of experience levels. The book minimizes reader confusion through a systematic progression of fundamentals: - Elastic airplane stability and control coefficients and derivatives - Method for determining the equilibrium and manufacturing shape of an elastic airplane - Subsonic and supersonic numerical examples of aeroelasticity effects on stability & control derivatives - Bode and root-locus plots with open and closed loop airplane applications, and coverage of inverse applications - Stability augmentation systems: pitch dampers, yaw dampers and roll dampers - Synthesis concepts of automatic flight control modes: control-stick steering, auto-pilot hold, speed control, navigation and automatic landing - Digital control systems using classical control theory applications with Z-transforms - Applications of classical control theory - Human pilot transfer functions." --Descripción del editor.

Book Description
An updated and expanded new edition of an authoritative book on flight dynamics and control system design for all types of current and future fixed-wing aircraft Since it was first published, Flight Dynamics has offered a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. Now updated and expanded, this authoritative book by award-winning aeronautics engineer Robert Stengel presents traditional material in the context of modern computational tools and multivariable methods. Special attention is devoted to models and techniques for analysis, simulation, evaluation of flying qualities, and robust control system design. Using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers, including aircraft designers, flight test engineers, researchers, instructors, and students. It introduces principles, derivations, and equations of flight dynamics as well as methods of flight control design with frequent reference to MATLAB functions and examples. Topics include aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment. The second edition of Flight Dynamics features up-to-date examples; a new chapter on control law design for digital fly-by-wire systems; new material on propulsion, aerodynamics of control surfaces, and aeroelastic control; many more illustrations; and text boxes that introduce general mathematical concepts. Features a fluid, progressive presentation that aids informal and self-directed study Provides a clear, consistent notation that supports understanding, from elementary to complicated concepts Offers a comprehensive blend of aerodynamics, dynamics, and control Presents a unified introduction of control system design, from basics to complex methods Includes links to online MATLAB software written by the author that supports the material covered in the book
