Abstract: An aircraft power plant is disclosed having a plurality of bladed rotors in flow communication driven by separate work producing devices. The work producing devices can take a variety of forms including an internal combustion engine and electric motor, for example. The bladed rotors can be associated with an aircraft pylon and can be driven independently to separate operating conditions to provide optimum performance. For example, the bladed rotors can be driven to separate operating conditions that improve a noise signature or performance of the aircraft.

The first linkage is operable to transmit rotational power to the open rotor module for rotating the plurality of variable-pitch blades. The system also includes an actuator operable to change a pitch of the plurality of variable-pitch blades. The system also includes a generator operable to generate electric power. The system also includes a second linkage extending between the power plant and the generator. The second linkage is operable to transmit rotational power to the generator. The generator is operable to convert the rotational power to electrical power. The system also includes a controller operably coupled to the actuator to vary a pitch of the plurality of variable-pitch blades.

Abstract: A roadable aircraft and an associated method are disclosed herein. The roadable aircraft includes a body extending along a longitudinal axis and operable to house a human occupant. The roadable aircraft also includes at least first and second wings each being selectively moveable relative to the body between a retracted position for stowing and an extended position for flight. Each of the first and second wings extend a wing cord along the longitudinal axis when in the extended position between a leading edge and a wing trailing-edge vectoring nozzle. The roadable aircraft also includes a system for directing first and second streams of air through the first and second wings, respectively, and out of the first and second wing trailing-edge vectoring nozzles such that thrust for the body is generated. In addition, embodiments of the invention can include a plurality of deployable, vectoring lift fans which are also capable of producing thrust.
