Abstract
A gas turbine engine has a turbine driving a gear reduction. The gear reduction drives a fan drive shaft assembly to, in turn, drive a fan rotor at a reduced speed relative to the turbine. A generator generates current upon rotation of the fan drive assembly. The generator supplies electric current to an electric motor driven pump. The electric motor driven pump delivers lubricant to components within the gear reduction.
