The approach of this book is to demonstrate how theoretical aspects, drawn from topics on airplane aerodynamics, aircraft structures, stability and control, propulsion, and compressible flows, can be applied to produce a new conceptual aircraft design. The book cites theoretical expressions wherever possible, but also stresses the interplay of different aspects of the design which often require compromises. KEY TOPICS: Coverage includes the conceptual design of an aircraft; iterative and repetitive calculations, and the different degrees of dependence of the aircraft characteristics on changing input conditions. MARKET: For professionals in the Aerospace Engineering field.
