Free rotating integrated motor propulsor

摘要

An integrated motor propulsor includes a rotor which a plurality of rotor blades adapted to rotate about a center axis. An outer ring surrounding the rotor contacts one of the rotor blades and has a field means positioned on the outer ring. A duct is in low friction contact circumferentially outside the outer ring. A stator is positioned in the duct to interact with the field means. The duct also has a plurality of pitch control apparatuses pivotally joined to outboard blades which extend radially outward from the duct.
