Flight Dynamics


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

General Aviation Dynamics. An Extension of the Cost Impact Study to Include Dynamic Interactions in the Forecasting of General Aviation Activity. Volume II. Research Methodology


Book Description

This report is the result of a series of research programs dealing with the cost impact effects on general aviation conducted by Battelle Memorial Institute - Columbus Laboratories. Past studies were aimed at developing a consistent data base and methodology for determining the influence of cost changes on both numbers of active aircraft and annual hours flown. During these studies, it became apparent that the complex nature of the general aviation system was not being adequately represented with a set of independent, log-linear regression equations. A method is needed which, (1) focuses on general aviation activity at the lowest possible level; that is, by individual user category/aircraft type subsegments; (2) recognizes the important causal interactions between pilots, aircraft, and annual hours flown; (3) Has the ability to assess various policy alternatives quickly; and (4) Can be easily modified as future forecasting requirements are identified. This report presents the results of a model development effort designed to satisfy the above objectives. Throughout the report, discussion of the model is couched in the terminology of system dynamics.
