General Electric GE36
... exhaust stream discharged through a seven-stage low pressure (LP) turbine, where each stator ring was 'unearthed' and free to move in the opposite direction to that of the ... variable pitch, fan blades was connected to the LP turbine rotor system, while the other set was connected to the contra-rotating LP turbine stators ... GE used a low speed, (effectively) 14 stage, LP turbine, rather than a conventional high speed LP turbine and reduction gearbox, to drive the fan rotor blades ...
Turbofan Configurations - Aft-fan Turbofan
... J79 turbojet, known as the CJ805-23, which featured an integrated aft fan/low pressure (LP) turbine unit located in the turbojet exhaust jetpipe ... Hot gas from the turbojet turbine exhaust expanded through the LP turbine, the fan blades being a radial extension of the turbine blades ... One of the problems with the aft fan configuration is hot gas leakage from the LP turbine to the fan ...
Geared Turbofan - Technology
... the overall cycle has been defined the tip speed required for the fan dictates the LP shaft rotational speed (i.e ... high radius ratios) the implied tip speeds of the LP turbine and (in this case) IP compressor are relatively low, which means extra turbine/compressor stages are required to keep the average ... Geared Turbofan, fitting a 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 ...
