Flight Dynamics

Flight Dynamics takes a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. While presenting traditional material that is critical to understanding aircraft motions, it does so in the context of modern computational tools and multivariable methods. Robert Stengel devotes particular attention to models and techniques that are appropriate for analysis, simulation, evaluation of flying qualities, and control system design. He establishes bridges to classical analysis and results, and explores new territory that was treated only inferentially in earlier books. This book combines a highly accessible style of presentation with contents that will appeal to graduate students and to professionals already familiar with basic flight dynamics. Dynamic analysis has changed dramatically in recent decades, with the introduction of powerful personal computers and scientific programming languages. Analysis programs have become so pervasive that it can be assumed that all students and practicing engineers working on aircraft flight dynamics have access to them. Therefore, this book presents the principles, derivations, and equations of flight dynamics with frequent reference to MATLAB functions and examples. By using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers. Introductions to aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment accompany the development of the aircraft's dynamic equations.

The Dynamics of Flight, The Equations

The Dynamics of Flight The Equations Jean-Luc Boiffier SUPA?RO and ONERA - CERT, France The study of aircraft flight is based upon the model formed by the flight dynamics equations, which are comprehensively evolved in this book. These equations and the associated hypotheses are the fundamental prerequisite of every study of flight dynamics. In this work, the equations are adapted to the study of the atmospheric or spatial flight of a rigid airplane, for which a series of successive simplifications are made, ranging from the flat and fixed Earth hypotheses to those of longitudinal decoupling and linearised flight. Several representations of the equations are developed with a precise formulation of the atmospheric perturbation influence (wind and turbulence). The definition of the equilibrium and pseudo-equilibrium notions is accompanied by an analytical and numerical general method for equilibrium research. Next, the linearisation and the decoupling operation, fundamental for the dynamic and analytical process of the equations, is developed. Major features include: * General equations of flight dynamics with successive simplifications and in several forms (calculation details appear in the appendix) * Precise formulation of atmospheric perturbation on the equations * Analytical and numerical methods for equilibrium research and linearisation * A compendium of rigorous definitions and notations of the numerous flight dynamics parameters * Onboard measures equations * Developments designed to solve practical difficulties in a thorough and simple way With its inclusion of both the theoretical and applied aspects of flight dynamics equations, this book serves as an essential tool for engineers, researchers and students working in the fields of aeronautics: flight dynamicists, automatic control systems specialists, aerodynamicists and specialists in structures.
