ABSTRACT:
A propeller engine system with means for generating electric power within a rotatable hub is disclosed. The means include a shaft extending into the hub so that the hub and shaft are differentially rotatable. Magnetic means are fixed to the shaft and winding means are fixed to the hub so that either rotation of the rotor shaft or hub induces an electric current in the winding means.
