ABSTRACT:
An STOL or VTOL winged aircraft comprises a fuselage and a fixed wing attached to the fuselage and extending outward from the two lateral sides thereof, forming one wing component extending outward from one side of the fuselage and a second wing component extending outward from the opposite side of the fuselage. At least one “thruster” is disposed in each wing component to provide vertical lift to the aircraft when the aircraft is stationary or moving forward only slowly. The thruster includes a shaft mounted for rotation in the respective wing component and extending substantially parallel to the wing axis and a plurality of fan blades attached to the shaft for movement of air. A shroud is preferably arranged in each wing component, adjacent to the fan blades, for directing the airflow downward or rearward. Ducted fans a preferably arranged on both sides of the aircraft for providing additional vertical thrust.
