Fundamentals of Jet Propulsion with Applications is an introductory text in air-breathing jet propulsion including ramjets, turbojets, turbofans, and propjets. Aimed at upper-level undergraduate and graduate students, the book provides coverage of the basic operating principles, from cycle analysis through component design and system matching. A basic understanding of fluid mechanics and thermodynamics is assumed, although many principles are thoroughly reviewed. Numerous examples and nearly 300 homework problems based on modern engines make this book an ideal teaching tool, as well as a valuable reference for practicing engineers. A CD included with the book contains example files and software to support the text.

Arvustused

'... This reviewer said of the first edition of this book that 'it deserves to be used wherever aircraft propulsion is taught'; and should enjoy a long and useful life. It is therefore now a pleasure to welcome the second edition ... Like the first edition, this book is highly recommended to all interested in the concepts and design issues of modern jet engines ...'. The Aeronautical Journal The Aeronautical Journal

Ronald D. Flack joined the faculty of the University of Virginia's School of Engineering and Applied Science in the mechanical and aerospace engineering department in 1976. He has authored more than 100 journal publications and more than 175 reports and papers. He has served as the chair of MAE and as director of the Rotating Machinery and Controls Industrial Research Program (ROMAC). Dr Flack has been chair of the ASME IGTI Education Committee and chair of the ASME regional committee of ME department heads, and he is an ASME Fellow. His research interests include experimental internal flows in turbomachines and fluid film bearings, leading to the extended life of turbomachines by reducing forces and vibrations and improved hydraulic efficiency of turbomachines.
