This valuable textbook describes those subjects important to conceptual, competitive stages of propulsion design and emphasizes the tools needed for this process. The text begins with a discussion of the history of propulsion and outlines various propulsion system types to be discussed such as cold gas systems, monopropellant systems, bipropellant systems, and solid systems. Included with the text is PRO: AIAA Propulsion Design Software, which allows the reader to proceed directly from understanding into professional work and provides the accuracy, speed, and convenience of personal computing. Also, the software contains conversion routines that make it easy to move back and forth between English and metric systems. A recommended text for professionals and students of propulsion.
