Updated edition of the successful textbook exploring cutting-edge developments in the field and Net-Zero aviation goals of 2050 Maintaining the successful foundation of previous editions, the fourth edition of Aircraft Propulsion is a forward-looking textbook on propulsion, from the basic principles to more advanced treatments in engine components and system integration, that focuses on the Net-Zero Aviation goals of 2050. This book explores the alphabet of the emerging technology in propulsion by emphasizing electrification and sustainable aviation fuels (SAF), including liquefied natural gas (LNG) and hydrogen. This book also covers advanced topics like flow control, adaptive cycle engines (ACE), hybrid-electric propulsion, pulse detonation engines (PDE), propulsion integration, and engine performance testing and instrumentation. Along with content updates, this new edition devotes a new chapter to supersonic and hypersonic propulsion. End-of-chapter problem sets are included as a learning aid with solutions available on a companion website. A quiz appendix with 45 10-minute quizzes helps readers test their knowledge at every stage of learning. Aircraft Propulsion includes information on: Engine thrust and performance parameters, gas turbine engine cycle analysis, and aircraft engine inlets and nozzlesCombustion chambers and afterburners, axial-flow compressor and fan aerodynamics, centrifugal compressor aerodynamics and gas turbine aerodynamics, and heat transfer and cooling technologiesAircraft engine component matching and off-design analysisAvailable on a companion website: Compressible flow with friction and heat, general aviation and uninhabited aerial vehicle propulsion systems, propeller theory, and chemical rocket propulsionAircraft Propulsion is an essential reference on the subject for aerospace and mechanical engineering students in their upper undergraduate or first-year graduate studies, practicing engineers in industry and research centers working on sustainability, and aviation industry engineers.

Written to teach students the nature of transonic flow and its mathematical foundation, this book offers a much-needed introduction to transonic aerodynamics. The authors present a quantitative and qualitative assessment of subsonic, supersonic and transonic flow around bodies in two and three dimensions. The book reviews the governing equations and explores their applications and limitations as employed in modeling and computational fluid dynamics.Some concepts, such as shock and expansion theory, are examined from a numerical perspective. Others, including shock-boundary-layer interaction, are discussed from a qualitative point of view. The book includes 60 examples and more than 200 practice problems. The authors also offer analytical methods such as Method of Characteristics (MOC) that allow readers to practice with the subject matter.The result is a wealth of insight into transonic flow phenomena and their impact on aircraft design, including compressibility effects, shock and expansion waves, shock-boundary-layer interaction and aeroelasticity.
