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
Hypersonic missiles--specifically hypersonic glide vehicles and hypersonic cruise missiles--are a new class of threat because they are capable both of maneuvering and of flying faster than 5,000 kilometers per hour. These features enable such missiles to penetrate most missile defenses and to further compress the timelines for a response by a nation under attack. Hypersonic missiles are being developed by the United States, Russia, and China. Their proliferation beyond these three could result in other powers setting their strategic forces on hair-trigger states of readiness. And such proliferation could enable other powers to more credibly threaten attacks on major powers. The diffusion of hypersonic technology is under way in Europe, Japan, Australia, and India--with other nations beginning to explore such technology. Proliferation could cross multiple borders if hypersonic technology is offered on world markets. There is probably less than a decade available to substantially hinder the potential proliferation of hypersonic missiles and associated technologies. To this end, the report recommends that (1) the United States, Russia, and China should agree not to export complete hypersonic missile systems or their major components and (2) the broader international community should establish controls on a wider range of hypersonic missile hardware and technology.

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
An optimization of air breathing hypersonic cruise vehicles was performed in order to determine basic configuration characteristics and performance trends. A distinctive feature of the investigation is that prediction techniques such as the method of characteristics were used to determine the flow field surrounding the vehicle; therefore, any interaction between the aerodynamic and propulsive flow fields is accounted for in a fundamental manner. The general class of vehicles considered in the study cruise in the Mach 8-12 speed regime, utilize a hydrogen fueled supersonic combustion ramjet engine, and can be geometrically characterized as two-dimensional wedgelike shapes. Configurations were optimized for maximum cruise range as determined from the Breguet range equation which incorporates a measure of the aerodynamic, propulsive, and volumetric efficiencies of a configuration. A generalized configuration model was defined by a discrete parameters which transformed the variational problem to a static or discrete optimization problem. The direct method of function optimization, utilizing search algorithms such as random point and adaptive creeper techniques, was employed to determine the value of the parameters defining the optimum configuration for cruise at design Mach numbers of 8, 10, and 12. The design parameter space in the vicinity of the optimum point was explored to show performance sensitivity. (Author).

Book Description
In order to reduce the design cycle time and cost and to improve the multi-disciplinary interactions at the preliminary design stage of supersonic air-breathing missiles, an automated optimization method has been developed for inlet/body integration in a concurrent engineering environment. Three disciplines of higher relevance have been considered for the shape optimization problem: propulsion, aerodynamics and electromagnetics. This paper describes the numerical method, which incorporates a genetic algorithm and three analysis modules into the optimization loop. The parametric model of the generic missile is presented. The optimization problem is defined and solved for a given mission and set of specifications. The problem is addressed in three phases corresponding to an increasing number of concurrent disciplines. This progression enables to emphasize the conflicting goals between the disciplines and to understand how the optimizer yields the best compromises. This preliminary study shows interesting results and strong potential for future development and industrial applications.
