  • Summary

    The detonation-driven shock tunnel is one of three important classes of hypersonic and high-enthalpy ground testing facilities that are based on the shock-heated principle. The theory and methods for developing the detonation-driven shock tunnels aiming at hypervelocity flow generation are summarized in this chapter. At first, the primary concepts for detonation drivers are presented to demonstrate their unique advantages for aerodynamic ground-based testing. The difficult problems arising from the development of hypervelocity shock tunnels for simulating flight conditions are identified and discussed in detail to address critical issues underlying the high-enthalpy shock tunnel design. Then, three kinds of detonation-driven shock tunnels are introduced, and their key techniques and performances are reviewed and discussed in detail. Finally, some experiments are summarized to demonstrate the capability of the detonation-driven hypersonic shock tunnel and the importance of the measurement techniques for hypersonic and high-temperature flow experiments. Both are the frontiers of high-enthalpy flow research for developing hypersonic vehicles.

  • Learn to design and improve state-of-the-art aerodynamic ground testing facilities in this comprehensive reference book, with particular focus on high-enthalpy shock tunnels. Including the latest advances in detonation-driven high-enthalpy shock tunnels, readers will discover how to extend test time with brand new concepts and duplicate real hypersonic flight test conditions. Through a systematic approach, the book describes technologies for a variety of different drivers in hypersonic and high-enthalpy shock tunnels. The fundamental theories for hypersonic and high-enthalpy shock tunnels are described step-by-step, with examples throughout, providing an accessible introduction. Built on years of real-world experience, this book examines in detail the advantages and challenges of improving test flow qualities, including increasing total pressure and enthalpy, model scale amplification and test-time extending for different types of shock tunnel drivers. This is an ideal companion handbook for aerospace engineers as well as graduate students.
