Aircraft Propulsion, 2nd Edition

Preface to the Second Edition

Since the first edition of this book appeared in 2008, the Uninhabited Aerial Vehicle (UAV) has gained wider interest and market share in aircraft industry. As a result, the second edition has a new chapter dedicated to General Aviation and UAV Propulsion Systems. The remaining changes to the second edition stem from technological advances in propulsion in recent years. For example in the commercial transport sector, we have witnessed the development of Ultra-High Bypass (UHB) turbofan engines with bypass ratio above 12. An enabling technology to UHB is the Geared Turbofan, which has also received an introductory coverage in the second edition. Other technological advances include Chevron Nozzle, Alternative “drop-in” Jet Fuels (AJF) and advanced heat exchanger in airbreathing rocket engine for single-stage-to-orbit application, which are introduced in the new edition.

Some of the reviewers and readers suggested an introductory presentation on propeller theory could well be integrated with the presentation of the turboprop engines. In response, I have added a section on propeller theory prior to the turboprop cycle analysis section. The instructors often wrote and asked for more problems at the end of chapters and as a result the new edition has about 50% more end-of-chapter problems than the first edition (i.e., 446 in 2E vs. 305 in 1E). There is an increased interest in Aerospace Engineering (AE) programs to offer propulsion system design as ...
