jet engine compressor

high pressure compressor of Pratt and Whitney PURE POWER 1000G turbofan engine In the PurePower PW1000G engine, a state of the art gear system separates the engine fan from the low pressure compressor and turbine, allowing each of the modules to operate at their optimum speeds. This enables the fan to rotate slower and while the low pressure compressor and turbine operate at a high speed, increasing engine efficiency and delivering significantly lower fuel consumption, emissions and noise. This increased efficiency also translates to fewer engine stages and parts for lower weight and reduced maintenance costs.
