Turbofan engines were first named as bypass turbojets by Rolls-Royce. Boeing sometimes refers to them as fanjets . Turbofan engines are the most reliable engines ever developed. Fundamentally, turbofan engines are fuel efficient and quiet, turbine-based engines. They feature continuous combustion and smooth rotation, unlike the internal combustion engine of automotives. The gas generator of a single-spool turbofan has three sections:
Fan unit and compressor section
Turbine sectionThe fan pressurizes air and feeds it aft. Most of this air goes around the engine core and is next ejected through a nozzle called a fan (or cold) nozzle. The rest goes through the engine core, where it is further compressed in a compressor and next then it mixes with the fuel and ignites. The hot expanding combustion efflux passes through the turbine section, spinning the turbine as it exits the engine.
