Abstract/Description

A system and method for implementing stage-by-stage counter rotation in a multi-stage axial compressor of a gas turbine engine. The system includes an electrical power gen­erator and an electric motor. A turbine-driven shaft connected to an armature of the electrical generator drives a first plural­ity of compressor blades. The electrical generator armature induces changing magnetic flux in the stator coils of the electrical generator which generates electrical power that is sent to a power control module. The power control module controls the electrical motor and excites the coils in the elec­tric motor stator which drives the electric motor armature. The electric motor armature drives a second shaft which drives a second plurality of compressor blades in an opposite direction to the first plurality of compressor blades.
