Beskrivning

Flight Simulation Software Explains the many aspects of flight simulator design, including open source tools for developing an engineering flight simulator Flight simulation is an indispensable technology for civil and military aviation and the aerospace industry. Real-time simulation tools span across all aspects of aircraft development, from aerodynamics and flight dynamics to avionics and image generation systems. Knowledge of flight simulation software is vital for aerospace engineering professionals, educators, and students. Flight Simulation Software contains comprehensive and up-to-date coverage of the computer tools required to design and develop a flight simulator. Written by a noted expert with decades of experience developing flight simulators in academia, this highly practical resource enables readers to develop their own simulations with readily available open source software rather than relying on costly commercial simulation packages. The book features working software taken from operational flight simulators and provides step-by-step guidance on software design, computer graphics, parallel processing, aircraft equations of motion, navigation and flight control systems, and more. Explains both fundamental theory and real-world practice of simulation in engineering designCovers a wide range of topics, including coding standards, software validation, user interface design, and sensor modellingDescribes techniques used in modern flight simulation including distributed architectures and the use of GPUs for real-time graphics renderingAddresses unique aspects of flight simulation such as designing flight control systems, visual systems, and simulator instructor stationsIncludes a companion website with downloadable open-source software and additional resourcesFlight Simulation Software is a must-have guide for all developers and users of simulation tools, as well as the ideal textbook for relevant undergraduate and postgraduate courses in computer science, aeronautical engineering, electrical engineering, and mechanical engineering programs.
