AND UNDERSTANDING

After accumulating a couple of thousand users (in academia and industry) from around the globe, this engine is due for an overhaul!

Since an overhaul is a heavy repair/maintenance process, then, in this second edition of my engine book, a number of significant changes have been made to the scope, organization, and focus. In this edition, I have strived to cope with the technological and environmental challenges associated with thrust/power production.

The scope of the book has been expanded to include rocket propulsion, unmanned aerial vehicles (UAVs), and biofuel. Therefore, three new chapters have been added. Two of them are on rocketry. The third is entitled Selected Topics and handles three hot topics: future trends in aeroengine design, UAV, and biofuel.

The book has 19 chapters organized in three parts. With this new material, it is now possible to teach two complete juniorsenior-level coursesone on aircraft and rocket propulsion and one on aeroengine design.

Other major content changes include the addition of internal combustion engines and propeller design. Moreover, since a long-distance rocket incorporates an airbreathing engine side by side with a rocket engine for sustained flight, there is a thorough analysis and discussion in the relevant chapters of intermeshing a rocket engine with either a ramjet, turbojet, or turbofan engine. Also, unducted fan (UDF) or propfan engines have regained the interest they previously enjoyed in the 1970s after the oil embargo; this was sufficient motivation for adding a detailed case study. Many new solved examples and nearly 100 new end-of-chapter problems based on real airbreathing engines and rocket engines have been developed for this edition.

, History and Classifications of Aeroengines, includes all changes in airbreathing engines to cover the period between the two editions (20072016). There is particular emphasis on geared and three-spool turbofan engines, scramjet engines, and solar aircraft.

, Performance Parameters of Jet Engines, includes details for range and fuel consumption for each flight phase of military aircraft as well as the point of no return and critical point for airliners. Performance analyses of many flying aircraft are provided. Thrust of rockets is also introduced.

, Pulsejet and Ramjet Engines, includes major changes. The pulsating nature of pulsejet engines and the analysis of Flying Bomb V-1 and pulse detonation engine are discussed. Classifications of ramjets based on flight speed (subsonic/supersonic), geometry (fixed/variable), type of fuel (solid/liquid), and nuclear/nonnuclear engines are given. The thermodynamics of double-throat and solid-fuel ramjets is introduced. Finally, the Boeing IM-99/CIM-10 Bomarc rocket, using both a liquid-fuel rocket and a liquid-fuel ramjet for its sustained flight, is analyzed.

, Turbojet Engine, addresses small engines used in cruise missiles, target drones, and other small unmanned air vehicles (UAVs), since larger ones are no longer employed due to their high noise and fuel consumption. Data for several micro-turbojets are given. Turbojet engines integrated with rocket engines (e.g., in Harpoon and Storm shadow rockets) for sustained flight are analyzed.

, Turbofan Engines, adds new material on triple-spool mixed/afterburning turbofan engines. The effect of air bleed on the performance of large three-spool engines is enhanced. The subject of turbofan engines used in powering rockets during sustained flight has been added. Many examples are worked out, including the Williams International F107-WR-402 turbofan powering the AGM-86 ALCM cruise missile launched from the Boeing B-52H Stratofortress bomber. Since a geared turbofan engine represents the recommended choice for the coming decadedue to its low noise and fuel consumptiona detailed performance analysis for a typical geared turbofan is given.
