The escalating use of aircraft in the 21st century demands a thorough understanding of engine propulsion concepts, including the
performance of aero engines. Among other critical activities,gas turbines play an extensive role in electric power generation,
and marine propulsion for naval vessels and cargo ships.
In the most exhaustive volume to date, this text examines the foundation of aircraft propulsion: aerodynamics interwoven with
thermodynamics, heat transfer, and mechanical design. With a finely focused approach, the author devotes each chapter to a
particular engine type, such as ramjet and pulsejet, turbojet, and turbofan. Supported by actual case studies, he illustrates
engine performance under various operating conditions.
Part I discusses the history, classifications, and performance of air breathing engines. Beginning with Leonardo and continuing on
to the emergence of the jet age and beyond, this section chronicles inventions up through the 20th century. It then moves into a
detailed discussion of different engine types, including pulsejet, ramjet, single- and multi-spool turbojet, and turbofan in
both subsonic and supersonic applications.
The author discusses Vertical Take Off and Landing aircraft, and provides a comprehensive examination of hypersonic scramjet and
turbo ramjet engines. He also analyzes the different types of industrial gas turbines having single-and multi-spool with intercoolers,
regenerators, and reheaters.
Part II investigates the design of rotating compressors and turbines, and non-rotating components, intakes, combustion chambers,
and nozzles for all modern jet propulsion and gas turbine engine systems, along with their performance. Every chapter concludes with
illustrative examples followed by a problems section; for greater clarity, some provide a listing of important mathematical relations
Aircraft Propulsion and Gas Turbine Engines, Second Edition builds upon the success of the book’s first edition, with the addition
of three major topic areas: Piston Engines with integrated propeller coverage; Pump Technologies; and Rocket Propulsion. The rocket
propulsion section extends the text’s coverage so that both Aerospace and Aeronautical topics can be studied and compared. Numerous
updates have been made to reflect the latest advances in turbine engines, fuels, and combustion. The text is now divided into three
parts, the first two devoted to air breathing engines, and the third covering non-air breathing or rocket engines.
"This book is one of the best on the market covering the topic of aircraft propulsion. There is no question that Aircraft
Propulsion and Gas Turbines, 2nd Edition deserves your attention should you consider employment in gas turbines industry
or are developing an academic course for your university. It is a resource that should be on everyone’s shelf."
This book provides a comprehensive basics-to-advanced course in an aero-thermal science vital to the design of engines for either
type of craft. The text classifies engines powering aircraft and single/multi-stage rockets, and derives performance parameters
for both from basic aerodynamics and thermodynamics laws. Each type of engine is analyzed for optimum performance goals, and
mission-appropriate engines selection is explained.
Aimed at graduate and final-year undergraduate students, this textbook provides a thorough grounding in the history
and classification of both aircraft and rocket engines, important design features of all the engines detailed, and
particular consideration of special aircraft such as unmanned aerial and short/vertical takeoff and landing aircraft.
End-of-chapter exercises make this a valuable student resource, and the provision of a downloadable solutions manual
will be of further benefit for course instructors
Effect of Film cooling of HP and IP turbines on Performance of triple Spool Turbofan Engines (Trent 700 type)
Film cooling will increase Turbine Inlet Temperature, which in turn increase the availble energy in LPT driving fan and exhaust speed.
Gain in available thrust will increase propulsive efficiency
