Abstract:
Systems and methods include providing an aircraft with a flight control system, a hybrid electrical or hybrid hydraulic propulsion system, and three ducted fan configuration. Each of two ducted fore fans include a single rotor system having multiple rotor blades, and a single ducted aft fan includes dual, coaxial, counter-rotating rotor systems each having multiple rotor blades. The aircraft is a vertical takeoff and landing (VTOL) aircraft that is capable of operation in an airplane mode and a helicopter mode and designed to provide an urban air-taxi that would relieve ground traffic congestion, reduce carbon emissions, and increase productivity, thereby providing a faster, more efficient means of transportation.
