Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes advances understanding of the initial optimization of civil airplanes and is a must-have reference for aerospace engineering students, applied researchers, aircraft design engineers and Cited by: Design and Multidisciplinary Optimization, namely: • MDO techniques truly can improve the weight and cost of an aircraft design concept in the conceptual design phase.

This is accomplished by a relatively small “tweaking” of the key design variables, and with no additional downstream costs. In effect, we get a better airplane for free. The multidisciplinary design optimization (MDO) approach is very crucial for the conceptual design of the aircraft, and this is due to the complex interaction between different disciplines, especially for the hypersonic vehicle.

In the hypersonic vehicle, the airframe and the engine are highly integrated. In the current survey, the research progress in the MDO approach has been Cited by: This textbook presents the process of aircraft conceptual design as seen in industry aircraft design groups.

It contains design methods, illustrations, tips, explanations and equations, and has extensive appendices with key data for design.

Aircraft conceptual design traditionally utilizes simplified analysis methods and empirical equations to establish the basic layout of new aircraft. Applying conventional optimization methods to aircraft conceptual design may yield solutions that are found to violate constraints; therefore, the designer's confidence, that proposed conceptual.

An area of product development that has been traditionally benefited from the use of MDO is that of aerial vehicle design. Over the years, MDO has been applied in many case studies of aircraft design and overall, it has shown very promising results in both the initial (conceptual) and the later (detailed) phases of the development process [10].
