Scramjet Propulsion Explore the cutting edge of HAP technologies with this comprehensive resource from an international leader in her field.

Scramjet Propulsion: A Practical Introduction delivers a comprehensive treatment of hypersonic air breathing propulsion and its applications. The book covers the most up-to-date hypersonic technologies, like endothermic fuels, fuel injection and flameholding systems, high temperature materials, and TPS, and offers technological overviews of hypersonic flight platforms like the X-43A, X-51A, and HiFIRE. It is organized around easy-to-understand explanations of technical challenges and provides extensive references for the information contained within.

The highly accomplished author provides readers with a fulsome description of the theoretical underpinnings of hypersonic technologies, as well as critical design and technology issues affecting hypersonic air breathing propulsion technologies. The book’s combination of introductory theory and advanced instruction about individual hypersonic engine components is ideal for students and practitioners in fields as diverse as hypersonic vehicle and propulsion development for missile defense technologies, launch aerospaceplanes, and civilian transports. Over 250 illustrations and tables round out the material. Readers will also learn from:

A thorough introduction to hypersonic flight, hypersonic vehicle concepts, and a review of fundamental principles in hypersonic air breathing propulsion
Explorations of the aerothermodynamics of scramjet engines and the design of scramjet components, as well as hypersonic air breathing propulsion combustors and fuels
Analyses of dual-mode combustion phenomena, materials structures, and thermal management in hypersonic vehicles, and combined cycle propulsion
An examination of CFD analysis, ground and flight testing, and simulation

Chapter 1 introduces the concept of hypersonic flight and describes high-speed air-breathing propulsion, highlighting the scramjet engine. After a summary of important
R&D programs, brief and pointed summaries of the history of hypersonic air-breathing propulsion are given along with the current status. Chapter 2 provides technical background, and it introduces the notation, defines important concepts, reviews fundamental formulas, and gives a qualitative glimpse of the vehicle-integrated propulsion system.

Chapter 3 is devoted to aerothermodynamics of vehicle-integrated scramjets, reviewing viscous flow phenomena and boundary-layer transition. The design and performance of the scramjet main components (inlet, combustor, and nozzle) are treated in Chapters 4, 5, and 8, respectively. The presentation is not what a design engineer would consider rigorous, but the material in these chapters conveys the essence of the scramjet flowpath design, and it also provides some ideas on the conditions and limitations associated with the performance relationships under study. Chapter 6 addresses endothermic fuels, while Chapter 7 gives a phenomenological description of dual-mode combustion, an important topic for scramjet engines that will operate in the low hypersonic flight regime.

Chapter 9 contains information on high-temperature materials, structures, and thermal management systems. Chapter 10 reviews combined cycle propulsion, including formulations for ideal cycle analysis of turbojets and ramjets. Chapter 11 focuses on ground testing, since sophisticated analysis and computational fluid dynamic (CFD) codes and methodology are used to obtain solutions to hypersonic air-breathing propulsion flowfields, Chapter 12 presents results obtained using computer codes of varying degrees of rigor, emphasizing their scope and contribution to the development of scramjet engines. An overview of flight testing is presented in Chapter 13, including the methods pursued, the experience gained during past scramjet demonstration flights, lessons learned, and infrastructure for safe testing of a scramjet-powered vehicle. The book concludes with an outlook of what the future may bring. Powering the Future of Transcontinental Flight and Access to Space encapsulates the current status of air-breathing propulsion R&D programs pursuing this future.

Perfect for researchers and graduate students in aerospace engineering, Scramjet Propulsion: A Practical Introduction is also an indispensable addition to the libraries of engineers working on hypersonic vehicle development seeking a state-of-the-art resource in one of the most potentially disruptive areas of aerospace research today.
