Turbofan Engine Schematic Diagram. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion.
All of this additional turbomachinery is colored green on the schematic.
This is a diagram of my turbofan jet engine.
The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan. It's also the part that you can see when you're looking at the front of a jet. In the turbofan engine, the core engine is surrounded by a fan in the front and an additional turbine at the rear.
