and the other, you can see on the books.
This book seeks to guide the student through the preliminary stages of the aircraft
design process. This is done by both Explaining the process itself (Chapters 1 and 2)
and by providing a variety of examples of actual student design projects (Chapters 3
xviii Introduction
to 10). The projects have been used as Coursework at universities in the UK and the U.S..
It should be noted that the project studies presented are not meant to provide a 'fill in
the blank 'template to be used by future students working on similar design problems
but to provide insight into the process itself. Each design problem, regardless of how
it may appear similar to an earlier aircraft design, is unique and requires a thorough
and systematic investigation. The project studies presented in this book merely serve
as examples of how the design process has been followed in the past by other teams
faced with the task of solving a unique problem in aircraft design
