Gas Turbine Engineering

Master the science, design, and real-world engineering behind one of the most important machines in modern aerospace and power generation.

It is a comprehensive engineering reference designed to connect thermodynamics, fluid mechanics, combustion, heat transfer, materials, mechanical design, controls, and maintenance into one coherent understanding of the modern gas turbine. The book is written for upper-level undergraduate students, graduate students, and practicing engineers who want to understand the gas turbine as an integrated machine rather than as a collection of unrelated components.

Gas turbines operate on a deceptively simple principle: compress air, add heat through continuous combustion, expand the hot gas through a turbine, and convert the resulting energy into shaft power or propulsion. But achieving high efficiency, reliability, power density, and durability requires careful coordination of aerodynamics, high-temperature materials, cooling technology, combustion systems, mechanical design, and control. This book develops those relationships from first principles and shows how each engineering decision affects the performance of the complete machine.

• Understand the working principles, classifications, applications, and major subsystems of modern gas turbines.
• Analyze the ideal Brayton cycle, real-cycle losses, pressure ratios, specific work, thermal efficiency, and back-work ratio.
• Evaluate component efficiencies, pressure losses, variable gas properties, turbine cooling bleed, and real engine performance.
• Explore regeneration, intercooling, reheat, combined-cycle power generation, and cogeneration.
• Understand the aerodynamics of axial-flow and centrifugal compressors, including velocity triangles, Euler work, stage loading, surge, choke, compressor maps, and variable geometry.
• Study combustion fundamentals, fuel-air relationships, flame stabilization, fuel injection, combustor architecture, liner cooling, ignition, and low-emission combustion.
• Analyze axial turbine aerodynamics, blade loading, reaction, stage efficiency, compressibility, choking, and turbine–compressor matching.
• Understand turbine heat transfer, internal blade cooling, film cooling, thermal-barrier coatings, creep, fatigue, oxidation, and blade-life limitations.
• Explore nickel-based superalloys, single-crystal materials, coatings, investment casting, cooling-hole manufacturing, additive manufacturing, and advanced ceramic materials.
• Apply gas-turbine principles to turbojets, turbofans, turboprops, aircraft thrust, bypass ratio, propulsive efficiency, and specific fuel consumption.
• Evaluate design-point and off-design operation, component matching, running lines, surge margin, transient behavior, and ambient-condition effects.
• Develop practical knowledge of gas-turbine operation, control, diagnostics, maintenance, reliability, availability, and life management.

The manuscript deliberately follows the working fluid through the machine—from thermodynamic cycle analysis to compressors, combustion, turbines, cooling and materials, aircraft propulsion, off-design behavior, emissions, mechanical design, and finally operation and maintenance—so that readers see how every subsystem interacts with the others.

Gas Turbine Engineering is especially valuable for:
