Optimal aircraft design is impossible without a parametric representation of the geometry of the airframe. We need a mathematical model equipped with a set of controls, or design variables, which generates different candidate airframe shapes in response to changes in the values of these variables. This model's objectives are to be flexible and concise, and capable of yielding a wide range of shapes with a minimum number of design variables. Moreover, the process of converting these variables into aircraft geometries must be robust. Alas, flexibility, conciseness and robustness can seldom be…mehr

Produktbeschreibung
Optimal aircraft design is impossible without a parametric representation of the geometry of the airframe. We need a mathematical model equipped with a set of controls, or design variables, which generates different candidate airframe shapes in response to changes in the values of these variables. This model's objectives are to be flexible and concise, and capable of yielding a wide range of shapes with a minimum number of design variables. Moreover, the process of converting these variables into aircraft geometries must be robust. Alas, flexibility, conciseness and robustness can seldom be achieved simultaneously. Aircraft Aerodynamic Design: Geometry and Optimization addresses this problem by navigating the subtle trade-offs between the competing objectives of geometry parameterization. It beginswith the fundamentals of geometry-centred aircraft design, followed by a review of the building blocks of computational geometries, the curve and surface formulations at the heart of aircraft geometry. The authors then cover a range of legacy formulations in the build-up towards a discussion of the most flexible shape models used in aerodynamic design (with a focus on lift generating surfaces). The book takes a practical approach and includes MATLAB , Python and Rhinoceros code, as well as real-life example case studies. Key features: Covers effective geometry parameterization within the context of design optimization Demonstrates how geometry parameterization is an important element of modern aircraft design Includes code and case studies which enable the reader to apply each theoretical concept either as an aid to understanding or as a building block of their own geometry model Accompanied by a website hosting codes Aircraft Aerodynamic Design: Geometry and Optimization is a practical guide for researchers and practitioners in the aerospace industry, and a reference for graduate and undergraduate students in aircraft design and multidisciplinary design optimization.

Autorenporträt
András Sóbester is a Senior Lecturer inAeronautical Engineering at the University of Southampton. Beyondaircraft geometry parameterization, his research interests includedesign optimization techniques (in particular, evolutionaryalgorithms, machine learning systems and surrogate model-assistedsearch heuristics), high altitude flight (on fixed wings orballoon-borne) and the use of additive manufacturing techniques inaircraft design. In terms of applying these technologies, his main focus is on thedesign of high altitude unmanned air vehicles for scientificapplications. He leads the ASTRA (Atmospheric Science ThroughRobotic Aircraft) initiative, which aims to develop high altitudeunmanned air systems for meteorological and Earth science research.Previous work includes research into reducing the environmentalimpact of passenger airliners through unconventional airframegeometries, undertaken as part of a Royal Academy of Engineering(RAEng) Research Fellowship. András also lectures on the University's AeronauticalEngineering undergraduate course - he leads the AircraftOperations and Mechanics of Flight, and the Aircraft Designmodules. Alexander I. J. Forrester was born and brought up inWirksworth, Derbyshire in the north of England. He studied for aMasters in aerospace engineering, followed by a PhD incomputational engineering at the University of Southampton where heis now a Senior Lecturer. He is a member of the Computational Engineering and Design ResearchGroup and the Institute for Life Sciences. His research interestslie in the efficient use of simulation and experiments in designoptimization. Alex leads the teaching of engineering design across theUniversity's Mechanical, Aeronautical and Ship Science first-yearundergraduate courses. He also teaches design optimization topostgraduate level and supervises the University'sundergraduate-developed human powered aircraft.
