‘Gas Turbine Propulsion Systems in Aerospace & Defense’ pulls together all of the systems and subsystems associated with gas turbine engines in aircraft and marine warship applications. The subject of engine (fuel) control has undergone major changes in the past 20 years due to the advent of the digital electronic control technology and therefore existing books on the subject are typically out of date with current methods. ‘Gas Turbine Propulsion Systems in Aerospace & Defense’ discusses the latest technologies in this area; including marine propulsion which is an emerging application area for the technology that involves some interesting modifications to aviation technologies. This book also fits well into the systems engineering focus of the Aerospace Series.Includes chapters on aircraft engine systems functional overview, marine propulsion systems, fuel control and power management systems, engine lubrication and scavenging systems, nacelle and ancillary systems, engine certification, unique engine systems and future developments in gas turbine propulsion systemsIncludes case studies of specific engines Includes applications within marine defenceAccompanied by a book companion website featuring full colour images
