Aerospace Propulsion

T.W. Lee, Arizona State University, USAT.W. Lee is currently an Associate Professor in the Mechanical and Aerospace Engineering department at Arizona State University. He has been teaching an Aerospace Propulsion class for the last 15 years and is the author of two books. His research interests include combustion, thermal-fluids, and propulsion systems and current projects include hypersonic inlets and supersonic reactors.

"Nevertheless this book covers the basics in a clear and easily accessible manner and would serve as a valuable study aid and as a companion text to the number of excellent, more specialised textbooks in this area such as Gas Turbine Theory by Savaranamutto, Rogers, Cohen and Straznicky (Prentice Hall. 2008 - Sixth edition) and Space Propulsion Analysis and Design edited by R. W. Humble et al. (McGraw-Hill Publishing Company. 1995)." (The Aeronautical Journal, 1 June 2014)
