The Vortex and The Jet

Reiner Decher is Professor Emeritus at University of Washington, Seattle WA USA (Department of Aeronautics and Astronautics). He completed his PhD degree at Massachusetts Institute of Technology.
Prof. Decher has published numerous technical papers in the subjects of aerodynamics, propulsion, energy conversion and gas dynamics. He has published several books in these fields, Energy Conversion (Oxford UP 1994), Direct Energy Conversion (Oxford UP 1997), Powering the World's Airliners (Pen & Sword, 2020), 2 books on rail transportation, 1 book history of engine technology: Turbulent Journey (Schiffer 2021), and 1 book as editor on WW II history: Invading Hitler's Europe (Pen & Sword 2020).
Prof. Decher has been Fulbright Research Professor at University of Karlsruhe Germany (1981-82), Fulbright Research Professor at Technical University of Berlin Germany (1998-99), Visiting Research Professor at Ecole Polytechnique de Lausanne Switzerland (1992) and Visiting Professor at MIT, (1991).

This open access book is an introduction for the lay reader to understand the basics of flight. The exposure is to the mysteries of lift generation by wings and the basic function of the jet propulsion engine. The text relies on simple descriptions of the physics of air flow without unduly involving mathematics. The text is richly illustrated with sketches and photographs to enrich verbal descriptions. 
The book takes the viewpoint that a reader does not have a background in the engineering of airplane components but is interested in the subject. The description is in terms of easy-to-understand terminology, occasional use of humor, references to everyday experiences, and occasionally to an algebraic relationship when that is unavoidable. 
This book would serve a student aspiring to be an engineer to begin grappling with the phenomena involved and the techniques used to analyze these phenomena. The practitioner, as well as the beginner, in the art of flying an airplane is well served with the knowledge exposed here.  
The text makes no apology for technical complexity. Its introduction is rigorous and provides a sound footing for further study.

Gives great introduction to the inner working of the modern jet engine

How and why does a wing generate lift?.- The bound vortex.- Frictionless air cannot provide lift: a paradox.- Drag, a nightmare or a challenge, depending on your point of view.- Pressure: The Bernoulli principle and flow energy conservation.- Pressure, pressure, it's all about pressure!.- Putting it all together in the real world.- The jet: fluid in motion.- Propulsion for flight: power or thrust?.- The compressor: engine keystone.- Bypass.- Other components of the jet engine.- More components: inlets, mixers, and nozzles.
