Advanced Aircraft Design: Conceptual Design, Technology and Optimization of Subsonic Civil Airplanes
Advanced Design (AD) is the name for the activity of a team of engineers and analysts during the early stages of an aircraft design and development process. The point of departure is a set of top-level requirements specifying payload/range capabilities, cabin accommodation, flight performance, operational, and environmental characteristics. The first design activity generates a conceptual baseline configuration defined by (electronic) drawings of its layout, a database specifying the physical characteristics and the essential technological assumptions, and an assessment of the feasibility of complying with the requirements. Designers may propose one or several concepts which are subsequently refined and compared during the second advanced design stage called the preliminary design. Conceptual design and preliminary design are crucial phases in the development process during which creativity and ingenuity are of paramount importance to support the far-reaching decisions that can make or break the programmed as a whole. Since the 1970s, aircraft design has become the subject of academic education and research at an increasing number of academic institutions which have an aerospace curriculum.

Many topics typical of aircraft design projects are nowadays covered in academic courses, and educational handbooks, and an abundance of software tools have become available to support students in their design exercises. Although many academic courses pay modest attention to aircraft design, a design-oriented approach to the traditional aeronautical disciplines can contribute to an improved understanding of aeronautical science as a whole. However, design handbooks are essentially based on existing or even obsolete technology and may produce unrealistic results when applied to future advanced aircraft design projects. And design technologies are becoming more complicated due to the introduction of integrated product design technology and multidisciplinary design optimization, subjects not covered in most handbooks. In writing this book it has been the author’s aim to contribute to the advancement of aircraft design (teaching) by emphasizing clear design thinking rather than sophisticated computation or using a huge collection of statistical information. Another orientation came from industrial design staff and academic teachers who indicated that they would be particularly interested in assessments of unusual aircraft concepts and examples of practical optimization in the early design stage. It was decided to focus on subsonic transports and executive (business) aircraft.
The present text combines the author’s academic teaching approach with numerous results from in-depth investigations on advanced technologies and innovative aircraft configurations reported since the 1970s. Particular attention is paid to research by staff of the aircraft design chair at Delft University of Technology between 1980 and 2000. Although some information about design methodologies and statistical data of recent airplane models are included, the result is not intended to be used as a handbook in the first place. Most of the material presented is readily understood by those who have previous experience with airplane design. The niche market for this book is formed by MSc and PhD students doing design-oriented research, academic staff teaching design, advanced airplane designers and applied scientists at aeronautical research laboratories.
