GEAR FAN-TYPE GAS-TURBINE MOTOR ARRANGEMENT Russian patent published in 2017 - IPC F02K3/06 

FIELD: engines and pumps.

SUBSTANCE: as a general matter, gas-turbine motor comprises a fan unit, a compressor unit, a combustion unit and a turbine unit. A gear unit can be used for the fan unit setting in motion, for instance, a gear unit that represents an epicyclic wheel train. In that kind of motors construction the axle, that is driven by one of the turbine unit, brings the epicyclic wheel train into action. This epicyclic wheel train rotates the fan at a speed that is different from the turbine unit rotative speed. As a result, the rotation speed of both turbine and fan units can be close to the optimum speeds. This provides the operational characteristics upgrade and increase in efficiency with respect to the usage of the required combination of the divers elements exposed design features of the described gas-turbine motor.

EFFECT: fan unit rotating capacity at a speed that is different from the turbine unit rotative speed and an upside potential of the total draft engine efficiency.
