Claim 7:
8. A method of providing propulsion to an aircraft, the method comprising:
providing an engine disposed within a fuselage of the aircraft;
providing two electrical generators disposed within the fuselage and connected to the engine;
providing two nacelles, each nacelle comprising a proprotor, and each nacelle housing two electric motors connected to the proprotor;
providing a fan coupled to the fuselage and connected to two additional electric motors, and each additional electric motor connected to the two electric generators;
driving the two electrical generators with the engine;
generating an electrical power from the two electrical generators;
transmitting the electrical power to the electric motors in the nacelles;
rotating the proprotors using the electrical motors in the nacelles to provide lift for vertical takeoff and landing in a helicopter mode; and
rotating the fan using the additional electric motors to provide thrust for forward flight during an airplane mode, wherein the airplane mode includes increasing power to the fan while decreasing power to the proprotors.
