This comprehensive volume presents a wide spectrum of information about the design, analysis and manufacturing of aerospace structures and materials. Readers will find an interesting compilation of reviews covering several topics such as structural dynamics and impact simulation, acoustic and vibration testing and analysis, fatigue analysis and life optimization, reversing design methodology, non-destructive evaluation, remotely piloted helicopters, surface enhancement of aerospace alloys, manufacturing of metal matrix composites, applications of carbon nanotubes in aircraft material design, carbon fiber reinforcements, variable stiffness composites, aircraft material selection, and much more. This volume is a key reference for graduates undertaking advanced courses in materials science and aeronautical engineering as well as researchers and professional engineers seeking to increase their understanding of aircraft material selection and design.

This volume presents an implicitly implemented large eddy simulation (ILES) by using the fifth order bandwidth-optimized WENO scheme. The chosen method is applied to make comprehensive studies on ramp flows with and without control at Mach 2.5 and Re=5760. Flow control in the form of microramp vortex generators (MVG) is applied. The results show that a MVG can distinctly reduce the separation zone at the ramp corner and lower the boundary layer shape factor under simulated conditions. A series of new findings about the MVG-ramp flow are obtained, including structures relevant to surface pressure, three-dimensional structures of the re-compression shock waves, a complete surface separation pattern, momentum deficit and a new secondary vortex system. A new mechanism of shock-boundary layer interaction control by MVG associated with a series of vortex rings is also presented. Vortex rings strongly interact with air flow and play an important role in the separation zone reduction. Additionally, readers will learn about the governing equation, boundary condition, high quality grid generation, high order shock capturing scheme and DNS inflow condition in detail. This volume will, therefore, serve as a useful reference for aerospace researchers using LES methods to study shock boundary layer interaction and supersonic flow control.

Conceptual Design of Green Transport Airplanes presents key information, methodologies, and modern tools for the conceptual design of airliners that comply with requirements to minimal environmental impact. The book is comprised of eight chapters that address relevant subjects such as airplane technological evolution, feasibility studies, design framework for conceptual design, and flight operations. Important issues and methods for an in-depth feasibility study are presented to facilitate the decision-making process of aircraft programs. These include examples of business plans for a 50-seat and 78-seat regional jets, description of design phases, market strategy, competition among manufacturers, regulatory requirements, and technology assessment. Readers will also be introduced to modern methodologies used in the conceptual design process of transport airplanes, such as configuration study, aerodynamics, flight stability and control, performance, certification requirements and the role of flight operations. Thus, the design process is explained in an integrated manner which paves the way towards a better understanding of an optimized aeronautical design environment where noise and emission constraints are taken into consideration. Conceptual Design of Green Transport Airplanes is an essential reference work for aeronautical engineering students and technicians as well as industry professionals involved in the aviation and environmental protection/regulation industry.
