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 nozzles
- Combustion chambers and afterburners, axial-flow compressor and fan aerodynamics, centrifugal compressor aerodynamics and gas turbine aerodynamics, and heat transfer and cooling technologies
- Aircraft engine component matching and off-design analysis
- Available on a companion website: Compressible flow with friction and heat, general aviation and uninhabited aerial vehicle propulsion systems, propeller theory, and chemical rocket propulsion
Aircraft 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.
