Selected Aerothermodynamic Design Problems of Hypersonic Flight Vehicles

In this book selected aerothermodynamic design problems in hypersonic vehicles are treated. Where applicable, it emphasizes the fact that outer surfaces of hypersonic vehicles primarily are radiation-cooled, an interdisciplinary topic with many implications.

This volume addresses selected aerothermodynamic design problems for three vehicle classes: winged reentry, non-winged reentry, and airbreathing hypersonic flight vehicles. Following an introductory chapter, the book presents the basics of flight trajectory mechanics, giving the aerothermodynamicist an understanding of the principal issues relevant to the field. In the following chapters, specific aerothermodynamic phenomena are discussed for the three vehicle classes, major simulation problems are singled out, and particular trends are examined. Available coefficients of longitudinal motion are presented for a variety of shapes of operational and studied vehicles, and aerothermodynamic issues of stabilization, trim, and control devices are treated. A full chapter is devoted to describing equations for aerodynamic forces, moments, center of pressure, trim, and stability. Another chapter focuses on multidisciplinary design aspects, presenting the mathematical models and the couplingprocedures in detail. Other chapters address the thermal state of a vehicle surface, thermal loads, and thermal surface effects, which are among the major topics of hypersonic vehicle design. The governing equations for flow in thermo-chemical non-equilibrium are presented, along with properties of the earth's atmosphere. Finally, constants and dimensions, symbol definitions, a glossary, acronyms, and a solution guide to problems are provided.

This book will be a great boon to graduate students, doctoral students, design and development engineers, and technical managers alike.

Different classes of hypersonic vehicles such as winged reentry vehicles or capsules are treated Written for scientists, engineers and advanced students in aerothermodynamics
