Opis

This first volume of Computational Modelling of Aircraft and the Environment provides a comprehensive guide to the derivation of computational models from basic physical & mathematical principles, giving the reader sufficient information to be able to represent the basic architecture of the synthetic environment. Highly relevant to practitioners, it takes into account the multi-disciplinary nature of the aerospace environment and the integrated nature of the models needed to represent it. Coupled with the forthcoming Volume 2: Aircraft Models and Flight Dynamics it represents a complete reference to the modelling and simulation of aircraft and the environment. All major principles with this book are demonstrated using MATLAB and the detailed mathematics is developed progressively and fully within the context of each individual topic area, thereby rendering the comprehensive body of material digestible as an introductory level text. The author has drawn from his experience as a modelling and simulation specialist with BAE SYSTEMS along with his more recent academic career to create a resource that will appeal to and benefit senior/graduate students and industry practitioners alike.

Recenzje

"Overall this is an excellent book which leads the reader though a clear description of the subject and is easily navigated so that it also makes a good reference. I would not hesitate to recommend this book to novice and experienced practitioners of Earth modelling, inertial navigation, GPS systems and the like." ( The Aeronautical Journal, May 2010)

Chapters include:

• Computational Modelling
• Platform Kinematics
• Geospatial Reference Model
• Positional Astronomy
• Geopotential Fields
• Atmosphere
• Appendices (an Introduction to MATLAB and Data and Functions).

All major examples within the book are implemented using MATLAB, and more high level, detailed mathematics is contained within the appendices in order to render the main body of the material digestible as an introductory level text. The author has drawn from his experience both as a modelling and simulation specialist with BAE Systems along with his more recent academic career to create a resource that will appeal to and benefit senior/ graduate students and industry practitioners alike.
