Gas turbines play an extremely important role in fulfilling a variety of power needs and are mainly used for power generation and propulsion applications. The performance and efficiency of gas turbine engines are to a large extent dependent on turbine rotor inlet temperatures: typically, the hotter the better. In gas turbines, the combustion temperature and the fuel efficiency are limited by the heat transfer properties of the turbine blades. However, in pushing the limits of hot gas temperatures while preventing the melting of blade components in high-pressure turbines, the use of effective cooling technologies is critical. Increasing the turbine inlet temperature also increases heat transferred to the turbine blade, and it is possible that the operating temperature could reach far above permissible metal temperature. In such cases, insufficient cooling of turbine blades results in excessive thermal stress on the blades causing premature blade failure.

The propulsion system is arguably the most critical part of the aircraft; it certainly is the single most expensive component of the vehicle. Ensuring that engines operate reliably without major maintenance issues is an important goal for all operators, military or commercial. Engine health management (EHM) is a critical piece of this puzzle and has been a part of the engine maintenance for more than five decades. In fact, systematic condition monitoring was introduced for engines before it was applied to other systems on the aircraft. Diagnostics and Prognostics of Aerospace Engines is a collection of technical papers from the archives of SAE International, which introduces the reader to a brief history of EHM, presents some examples of EHM functions, and outlines important future trends.

More than 120 authors from science and industry have documented this essential resource for students, practitioners, and professionals. Comprehensively covering the development of the internal combustion engine (ICE), the information presented captures expert knowledge and serves as an essential resource that illustrates the latest level of knowledge about engine development. Particular attention is paid toward the most up-to-date theory and practice addressing thermodynamic principles, engine components, fuels, and emissions. Details and data cover classification and characteristics of reciprocating engines, along with fundamentals about diesel and spark ignition internal combustion engines, including insightful perspectives about the history, components, and complexities of the present-day and future IC engines.

EVERYTHING WORKS WONDERFULLY is a 250-page A4 softback book written to provide a structured source of guidance and reference information on Servitization and the management of physical assets for people at all levels in industry: • Senior executives considering the expansion of their businesses into the provision of Asset Management services for the products they design and manufacture; • Middle management wishing to know what needs to be done to look after the assets they are responsible for and who to approach for help; • ‘Hands-on’ engineers looking for contacts and advice on detailed tools and techniques. • Academics may also find the book useful as a source of contacts and ideas for research.

The World Championship Grand Prix (WCGP) is the premier championship event of motorcycle road racing. The WCGP was established in 1949 by the sport's governing body, the Fédération Internationale de Motocyclisme (FIM), and is the oldest world championship event in the motorsports arena. This book, developed especially for racing enthusiasts by motorsports engineering expert Dr. Alberto Boretti, provides a broad view of WCGP motorcycle racing and vehicles, but is primarily focused on the design of four-stroke engines for the MotoGP class. The book opens with general background on MotoGP governing bodies and a history of the event’s classes since the competition began in 1949. It then presents some of the key engines that have been developed and used for the competition through the years. Technologies that are used in today’s MotoGP engines are discussed.

The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements.

This new ASTM manual brings together the various test procedures that technicians need to diagnose the contamination in fuels and fuel systems. It also suggests the means for detection and control of microbial contamination. As a complement to ASTM D6469 Standard Guide for Microbial Contamination in Fuels and Fuel Systems, this new publication provides an overview of: o Microbiological principles underlying fuel and fuel system biodeterioration o Sample collection and handling o Recommendations for disinfecting and removing microbial contamination from fuels and fuel systems o A variety of diagnostic tests It applies to furnace, aviation gasoline, diesel, aviation turbine, marine, industrial gas turbine, kerosene, gasoline, fuel systems, crude oil, and all liquid petroleum fuels. This is a valuable resource for professionals with a limited microbiological understanding of the symptoms, occurrences, and consequences of chronic microbial contamination.

Direct Injection Systems: The Next Decade in Engine Technology explores potentials that have been recognized and successfully applied, including fuel direct injection, fully variable valve control, downsizing, operation within hybrid scenarios, and use of alternative fuels.

This book addresses the problem of surface protection for aircraft engine turbine blades. Information describes and details a methodology for optimizing turbine blade surface protection; the performance of protective coatings is assessed and evaluated by the complex interconnections of their chemical and phase composition, structure, and physical-mechanical properties; the properties of overlay coatings are given for the wide range of compositions, including the possible coatings states after their production and long-term service; and the principles for calculating the stresses and strains for coated turbine blades are reviewed.

Superalloys provide the most reliable and cost-effective means of achieving high operating temperature and stress conditions in aircraft and industrial gas turbines and in a wide variety of other applications. This book covers virtually all technical aspects related to the selection, processing, use, and analysis of superalloys. Coverage of alloy selection provides many tips and guidelines that the reader can use in identifying an appropriate alloy for a specific application.

This book chronicles the development, production, and application of what was arguably the finest aircraft piston engine ever produced - the Pratt & Whitney R-2800. It powered many of the significant fighters and medium bombers of the conflict, and went on to power many other military and commercial aircraft.

While it took the demands of two World Wars to bring aviation into acceptance by the general public, it was a relative handful of engineers, entrepreneurs, and pilots who positioned the technology and resources necessary to make aviation one of the deciding factors in ending World War II. This book attempts to illuminate some of the historically significant technical developments that were incorporated into World War II aircraft engines that directly contributed to the execution and tactics of the war. Engines detailed in the book include those from these manufacturers: Rolls-Royce Bristol, Napier General Electric Pratt and Whitney Allison Wright Aeronautical Corporation
