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.
