Description
Book SynopsisAerospace propulsion devices embody some of the most advanced technologies, ranging from materials, fluid control, and heat transfer and combustion. In order to maximize the performance, sophisticated testing and computer simulation tools are developed and used.
Trade ReviewNevertheless 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 Theoryby Savaranamutto, Rogers, Cohen and Straznicky (Prentice Hall. 2008 Sixth edition) and Space Propulsion Analysis and Designedited by R. W. Humble et al. (McGraw-Hill Publishing Company. 1995). (The Aeronautical Journal, 1 June 2014)
