Book Description
This study was undertaken in response to a request by the U.S. Air Force that the National Research Council (NRC) examine whether the technologies that underlie the concept of a hypersonic, air-launched, air-breathing, hydrocarbon-fueled missile with speeds up to Mach 81 can be demonstrated in time to be initially operational by 2015. To conduct the study, the NRC appointed the Committee on Review and Evaluation of the Air Force Hypersonic Technology Program, under the auspices of the Air Force Science and Technology Board.

Book Description
In this project, a hypersonic airbreathing cruise missile is designed through an optimization process. The main use of this futuristic weapon technology is to be employed against enemy ships while being launched from an Mk-41 VLS launcher, the most widespread VLS in the world. In this optimization process and for this type of missile, Genetic Algorithms and Monte Carlo simulations are used to find an optimal solution for the rocket booster engine, the scramjet engine, aerodynamics and warhead sizing. With this data, trajectory, stability and manoeuvrability is studied to determine the performance of the missile. Other aspects concerning the missile materials of the airframe and dome are discussed on a qualitative way and no structural analysis is studied within this project. It should be noted that hypersonic weapons are mature technologies, and the only information about them are research papers regarding their aerodynamics and propulsion systems. Then, the only built hypersonic vehicles are experimental, meaning that the baseline data to start design process scarce. This brings a great challenge to this project, where creativity and the use of analytical expressions for rapid missile synthesis and conceptual design is a must. On the other side, due to the complex behaviour of hypersonic flows, this adds difficulties to our research since most of the methods employed are numerical, which can be calculated easily on a CFD in the final stages of the design, but they are not fast enough to be implemented on the initial stages of design. The final results prove that the methods employed for initial sizing are accurate enough to model a CAD design which can be used as a baseline for future research in this technology. To conclude with, the final results obtained with the algorithms helps us to understand the effects on design, especially when flying at high Mach numbers where the classical configuration of airframe, wings and tail must be radically redesigned to more aerodynamic efficient bodies such as Waveriders. Regarding to the optimization process, objective functions were changed manually to find better results at each iteration of the optimization process but better techniques such as local search methods used in artificial intelligence could be employed.

Book Description
Design and Manufacture of Structural Composites provides an overview of the main manufacturing challenges encountered when processing fibre-reinforced composite materials. Composites are unique in that the material is created at the same time as the structure, forming a very close link between the constituents, the manufacturing process and the resulting mechanical performance. This book takes an in-depth look at material choices and the intermediate steps required to convert different fibre and matrix combinations into finished products. It provides an insight into recent developments for each of the manufacturing processes covered, addressing design, cost, rate and mechanical performance. Topics covered include an introduction to composite materials, material preforming and conversion, moulding, digital design and sustainability, which addresses waste reduction, disassembly and fibre recovery. This book has been developed primarily as a teaching resource with contributions from leading experts in the field. The content has evolved from courses given by the authors to mechanical engineering and materials science students, at both undergraduate and postgraduate levels. It also draws upon experience gained during research projects and from leading industry experts. It therefore provides non-specialists with a valuable introduction to composite manufacturing techniques, helping to determine the most suitable manufacturing routes and to understand the challenges associated with the production of high-performance composite components. - Provides an overview of the most common manufacturing routes for fibre reinforced composites, including the influence of the manufacturing route on mechanical properties, production volume and component cost - Discusses recent advances in composite manufacturing, including the use of automation, process simulation, digital factories, and solutions to improve sustainability - Looks at where the composites sector is heading and discusses some of the challenges faced by end-users looking to scale up production and increase the uptake of fibre-reinforced composites for structural applications

Book Description
The manufacturing processes of composite materials are numerous and often complex. Continuous research into the subject area has made it hugely relevant with new advances enriching our understanding and helping us overcome design and manufacturing challenges. Advances in Composites Manufacturing and Process Design provides comprehensive coverage of all processing techniques in the field with a strong emphasis on recent advances, modeling and simulation of the design process. Part One reviews the advances in composite manufacturing processes and includes detailed coverage of braiding, knitting, weaving, fibre placement, draping, machining and drilling, and 3D composite processes. There are also highly informative chapters on thermoplastic and ceramic composite manufacturing processes, and repairing composites. The mechanical behaviour of reinforcements and the numerical simulation of composite manufacturing processes are examined in Part Two. Chapters examine the properties and behaviour of textile reinforcements and resins. The final chapters of the book investigate finite element analysis of composite forming, numerical simulation of flow processes, pultrusion processes and modeling of chemical vapour infiltration processes. - Outlines the advances in the different methods of composite manufacturing processes - Provides extensive information on the thermo-mechanical behavior of reinforcements and composite prepregs - Reviews numerical simulations of forming and flow processes, as well as pultrusion processes and modeling chemical vapor infiltration
