Abstract/Description

A multi-stage axial compressor incorporating a counter-rota­tional movement is provided with a series of rotors mounted along and driven by a driveshaft, and a geared counter-rotat­ing outer casing. A planetary gear system is assembled along a static casing, which can be assembled as a forward or aft casing for the compressor. The bearings of the planetary gear system typically will be aligned concentrically with a center rotor drum assembly mounted along the single driveshaft. The counter-rotating drum assembly will be assembled over the rotor drum assembly and will be engaged by the forward and aft casings so as to provide for counter-rotation of selected ones of the rotors driven by the driveshaft of the compressor.
