    en.wikipedia.org/wiki/Pratt_&_Whitney_PW1000G

    The Pratt & Whitney PW1000G family, also marketed as the Pratt & Whitney GTF (geared turbofan), is a family of high-bypass geared turbofan engines produced by Pratt & Whitney. Following years of development and testing on various demonstrators, the program officially launched in 2008 with the PW1200G destined for the Mitsubishi SpaceJet (a ...

  3. Geared turbofan - Wikipedia

    en.wikipedia.org/wiki/Geared_turbofan

    In a geared turbofan, a planetary reduction gearbox between the fan and the LP shaft allows the latter to run at a higher rotational speed thus enabling fewer stages to be used in both the LP turbine and the LP compressor, increasing efficiency and reducing weight. However, some energy will be lost as heat in the gear mechanism and weight saved ...

    The PLF1A-2 had a 40 in diameter (100 cm) geared fan stage, produced a static thrust of 4,320 lb (1,960 kg), [44] and had a bypass ratio of 6:1. [45] The General Electric TF39 became the first production model, designed to power the Lockheed C-5 Galaxy military transport aircraft. [22] The civil General Electric CF6 engine used a derived design.

  9. Bypass ratio - Wikipedia

    en.wikipedia.org/wiki/Bypass_ratio

    The bypass ratio (BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. [1] A 10:1 bypass ratio, for example, means that 10 kg of air passes through the bypass duct for every 1 kg of air passing through the core.
