Book Description

This is the second edition of Cumpsty's excellent self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engines. Through two engine design projects, first for a new large passenger aircraft, and second for a new fighter aircraft, the text introduces, illustrates and explains the important facets of modern engine design. This edition has been thoroughly updated and revised, including a new appendix on noise control and expanded treatment of combustion emissions. Suitable for student courses in aircraft propulsion, and an invaluable reference for aerospace engineers.

This text provides a self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engines. Through two engine design projects, the first for a new large passenger aircraft and the second for a new fighter aircraft, the author introduces, illustrates and explains the important facets of modern engine design. Individual sections cover aircraft requirements and aerodynamics, principles of gas turbines and jet engines, elementary compressible fluid mechanics, bypass ratio selection, scaling and dimensional analysis, turbine and compressor design and characteristics, and design optimization, as well as off-design performance.

Although Cumpsty assumes familiarity with basic fluid mechanical ideas, he provides background where necessary. The book emphasizes principles and ideas, with simplification and approximation used where this helps understanding. Many exercises and a detailed glossary support and reinforce the text. This book is suitable for student courses in aircraft propulsion and jet engine design and will be invaluable as a guide and reference for many engineers in the engine and airframe industry who are specialists outside the area of engine performance and overall aerothermal design.

Customer Reviews

This book keeps up with the promise in the title. It is a easily readable guide to design and perfomance of jet engine with a rigorous treatise of each field, even if the level remains simple.

In fact the mathematical exposition is quite accessible, without a full analytical presentation. Nevertheless the formulae are clearly given with an effective theorical background when needed. Since the volume target is to clarify ideas and principles, each topic is attractively examined, emphasizing the qualitative treatment over the quantitative analysis to improve understanding of physical phenomena. This facet is quite useful because it allows an overall comprehension in mastering design process of jet engine. Besides, the emphasis on having a clear picture of principles provides the basis for a fair evaluation of engine perfomances under real conditions.

As a guide or a reference, this work has neatly achived its goal.

hey, how are you? I don't know what I must suppose to write here, but I'm so happy to do this.
