Abstract

Rotary electric engines, aircraft including the same, and associated methods. A rotary electric engine includes a nacelle, a fan configured to generate thrust, a stator operatively coupled to the nacelle, and a rotor operatively coupled to the fan. The fan includes a plurality of fan blades. The rotor includes a plurality of rotor magnets operatively coupled to respective blade tips of the fan blades. The stator includes a plurality of field coils configured to produce a magnetic interaction between the field coils and the rotor magnets to rotate the fan. In examples, the stator is configured to rotate each field coil relative to the nacelle. In examples, an aircraft includes one or more rotary electric engines pivotally mounted within engine mount regions. In examples, a method of operating an aircraft includes operating one or more rotary electric engines in a vertical lift configuration and in a forward flight configuration.
