With up to 35,000 pounds of thrust, the PW1100G-JM, the modern engines from the Pratt & Whitney GTF™ engine family, can get an A320neo into the air. The fan rotor, the clearly visible compressor rotor at the front, provides the main thrust. It is driven by the low-pressure turbine, which runs particularly fast in the GTF engine and ensures greater efficiency. This is made possible by the gearbox installed in the GTF, which decouples the low-pressure turbine and the fan from each other. This allows both to run at their optimum speed – the fan slower, the low-pressure turbine faster. Turbine, gearbox and fan are essential components of a modern turbofan engine. And what role do the compressor and combustor actually play?
