The journey from an aeronautical engineer's design to a working aircraft is one which begins in the classroom. This textbook provides the resources students need to understand the methods and thought processes involved in designing aircraft. The book provides a working knowledge of how an aircraft is shaped and optimized to perform specific missions by countless design decisions. It seeks to provide motivation throughout a student's academic career by giving an idea of the design process and providing a foundation for more advanced studies in aeronautical and aerospace engineering. End of chapter problems give a summary of concepts and features and provide an opportunity to analyze and synthesize industry examples and their applications.
