Book excerpt: Hybrid Rocket Propulsion Design Handbook provides system scaling laws, design methodologies, and a summary of available test data, giving engineers all the tools they need to develop realistic hybrid system designs.Important supporting theory from chemistry, thermodynamics, and rocket propulsion is addressed, helping readers from a variety of backgrounds to understand this interdisciplinary subject. This book also suggests guidelines for standardized reporting of test data, in response to difficulties researchers have in working with results from different research institutes. - Covers general theory, recent advances and current fragmented experimental results of hybrid rocket engines - Outlines testing standards for hybrid researchers - Provides guidance on how to use a freely available online code from NASA
