Follow a parcel of air through a jet engine — squeezed, burned, expanded, thrown out of the back — with the cycle worked out live at every step, then see why airliner fans keep growing and why a car's turbocharger is a little gas turbine.

How jet engines work and what their numbers mean: an animated cutaway of turbojet, turbofan, turboprop, turboshaft, ramjet and afterburning engines with numbered stations; ideal and real Brayton cycle analysis at any Mach and altitude — thrust, TSFC, efficiencies, T–s and P–v diagrams and trade studies; compressor stages, draggable velocity triangles and a compressor map with surge margin; approximate figures for real engine families; and fuel, run time and start-up for model turbojets.
