A modern turbofan engine takes air in at the front, subjects it to a sequence of thermodynamic processes — compression, combustion, expansion — and expels it at the rear at a velocity sufficient to propel a 400-ton aircraft across an ocean. The peak temperature inside the combustion chamber exceeds 2,000 Kelvin — hot enough to melt the nickel alloys surrounding it. The turbine blades operate continuously in that environment at rotational speeds producing tip velocities near the speed of sound. That they don't melt, don't fracture, and produce reliable thrust for tens of thousands of hours is the result of materials science, thermodynamic engineering, and manufacturing precision operating at the absolute frontier of what human industry can achieve. This series examines the jet engine from first principles: the thermodynamic cycle that defines its efficiency limits, the aerodynamic engineering of the compressor, the combustion chemistry, the extraordinary metallurgy of turbine blades, the mathematics of thrust, the engineering evolution from Whittle's first turbojet to the geared turbofan, and where propulsion engineering is heading next.
