A system for transferring mechanical torque variably between a plurality of rotating machines in a turbofan engine. Two devices are used, where the first device relies upon magnetic properties of a planetary magnetic gearbox to couple the magnetic machines. The second device is used to variably control the torque transfer between the magnetic machines. The system couples rotating shafts rotating at differing speeds within a turbofan engine for controllably transferring power. To transfer power in the system, a fixed gear ratio is obtained by coupling the...
The invention claimed is: 1. A system for variable coupling of a high pressure spool and a low pressure spools to power a generator in a turbofan engine, the system comprising: a differential gear portion having a first input portion, a second input portion, and an output shaft; an electromagnetic variable transmission having an independently rotatable inner rotor portion and an independently rotatable outer rotor portion, the inner rotor portion coupled with one of the high pressure spool and the low pressure spool, and the outer portion connected to t...
