ELECTRICAL POWER GENERATION APPARATUS FOR CONTRA- ROTATING OPEN-ROTOR AIRCRAFT PROPULSION SYSTEM

摘要

An electrical power generation apparatus is embedded in a contra- rotating propulsion system that includes overlapping first and second shafts operatively connected for counter-rotation about a common axis. The electrical power generation apparatus includes a winding mounted to one of the shafts and a field array mounted to the other of the shafts adjacent to the winding. Relative rotation of the winding and the field array induces electrical current in the winding.
