CFM56-5A Turbofan Engine Cutaway Model — 3D Printable Display

This is a 3D printable scaled cutaway model of the CFM56-5A high-bypass turbofan engine, famously used on the Airbus A320 family. The design exposes the internal flow path—fan, booster, multi-stage compressors, combustor, and turbine stages—allowing viewers to clearly understand how air moves and energy is extracted inside a modern jet engine.

The model includes a presentation stand and an engraved information plaque featuring real engine specifications such as thrust rating, manufacturer, first run date, major aircraft applications, and total units produced. It serves as a highly visual teaching, reference, or display piece for aerospace students, engineers, hobbyists, pilots, and aviation enthusiasts.

This is a non-functional educational model intended for demonstration and desktop display.
