Why Do Modern Jet Engines Have Such Large Fans?

WebThe air does bypass the engine core, but it is accelerated by the N1 fan and provides thrust as it is expelled rearward out of the engine. Thrust from the bypass air can contribute more than half of the total thrust produced by the engine (upwards of 80% of the total thrust for some engines in certain phases of flight).

"The turbofan was invented to improve the fuel consumption of the turbojet. It would do this by increasing the mass and lowering the speed of the propelling jet compared to that of the turbojet. This would be done mechanically by adding a ducted fan rather than using viscous forces by adding an ejector, as first envisaged by Whittle. " - Bypass ratio gas turbine engines
