Web1949: Turbojet engines are used for commercial purpose for the first time. 1953: North American Aviation product, YF-100 Super Sabre becomes the first airplane powered by a turbojet to break the sound barrier. 1964: … 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.
