What planes use LEAP engines?
How do geared turbofan engines work?
A geared turbofan engine is a variant of a conventional turbofan engine in which a reduction gearbox is installed between the fan and the low pressure (low speed) turbine. In a conventional turbojet engine, the fan, low pressure compressor and low pressure (low speed) turbine are all rigidly joined by a single shaft.
