A comprehensive review of the science and engineering behind future propulsion systems and energy sources in sustainable aviation

Future Propulsion Systems and Energy Sources: in sustainable aviation is a comprehensive reference that offers a review of the science and engineering principles that underpin the concepts of propulsion systems and energy sources in sustainable air transportation. The author – a noted expert in the field – examines the impact of air transportation on the environment and reviews alternative jet fuels, hybrid-electric and nuclear propulsion and power. He also explores modern propulsion for transonic and supersonic-hypersonic aircraft and the impact of propulsion on aircraft design.

Climate change is the main driver for the new technology development in sustainable air transportation. The book contains critical review of gas turbine propulsion and aircraft aerodynamics; followed by an insightful presentation of the aviation impact on environment. Future fuels and energy sources are introduced in a separate chapter. Promising technologies in propulsion and energy sources are identified leading to pathways to sustainable aviation. To facilitate the utility of the subject, the book is accompanied by a website that contains illustrations, and equation files. This important book: 

  • Contains a comprehensive reference to the science and engineering behind propulsion and power in sustainable air transportation
  • Examines the impact of air transportation on the environment
  • Covers alternative jet fuels and hybrid-electric propulsion and power
  • Discusses modern propulsion for transonic, supersonic and hypersonic aircraft
  • Examines the impact of propulsion system integration on aircraft design

Written for engineers, graduate and senior undergraduate students in mechanical and aerospace engineering, Future Propulsion Systems and Energy Sources: in sustainable aviation explores the future of aviation with a guide to sustainable air transportation that includes alternative jet fuels, hybrid-electric propulsion, all-electric and nuclear propulsion.
