Example doors for ducted fan inlet openings are disclosed herein. An example apparatus disclosed herein includes a door and a duct of a ducted fan unit extending through a body of an aircraft. The duct of the example apparatus defines a passageway between a first opening in a first side of the body and a second opening in a second side of the body opposite the first side. The example apparatus also includes an actuation system to move the door between a first position in which the door is disposed over the first opening and a second position in which the door is disposed over the first side of the body and outside of a diameter of the first opening. In the example apparatus, the door is orientated generally parallel to the first side of the body throughout movement of the door between the first position and the second position.

1. An apparatus comprising: a door;a duct of a ducted fan unit extending through a body of an aircraft, the duct defining a passageway between a first opening in a first side of the body and a second opening in a second side of the body opposite the first side; andan actuation system including a mov
1. An apparatus comprising: a door;a duct of a ducted fan unit extending through a body of an aircraft, the duct defining a passageway between a first opening in a first side of the body and a second opening in a second side of the body opposite the first side; andan actuation system including a movable carriage to move the door between a first position in which the door is disposed over the first opening and a second position in which the door is disposed over the first side of the body and outside of a diameter of the first opening, the door orientated parallel to the first side of the body throughout movement of the door between the first position and the second position, wherein the carriage is moveable along a linear path that causes the door to move along (A) an arcuate path between the first position and a lifted position separated from the first opening and (B) a linear path between the lifted position and the second position. 2. The apparatus of claim 1, wherein the body of the aircraft is a fuselage, a wing, a canard or an empennage. 3. The apparatus of claim 1, wherein, in the second position, the door is disposed aft of the first opening. 4. The apparatus of claim 1, wherein, in the first position, a top surface of the door is substantially flush with a skin on the first side of the body adjacent the first opening. 5. The apparatus of claim 1, wherein the door is a substantially unitary piece or component. 6. The apparatus of claim 1, further including a recess formed in the first side of the body around the first opening, the door disposed in the recess when in the first position. 7. The apparatus of claim 1, wherein the door is a first door and the actuation system is a first actuation system, further including: a second door including a plurality of louvers disposed in the second opening on the second side of the body; anda second actuation system to rotate the louvers between an open position, a closed position, and any position between the open position and the closed position. 8. The apparatus of claim 1, wherein a profile of the door substantially matches a profile of the first side of the body adjacent the first opening. 9. A method comprising: moving, via a carriage coupled to a door of a ducted fan inlet opening on an aircraft, the door between a closed position in which the door is disposed over the inlet opening and a retracted position in which the door is disposed over a body of the aircraft and outside of a diameter of the inlet opening, wherein the moving of the door between the closed position and the retracted position includes (A) moving the door along an arcuate path between the closed position and an intermediate position in which the door is spaced above the inlet opening and (B) moving the door along a substantially linear path between the intermediate position and the retracted position, and wherein the door remains in a horizontal orientation throughout the movement between the closed position and the retracted position. 10. The method of claim 9, wherein a diameter of the door is the same as or larger than a diameter of the inlet opening. 11. The method of claim 9, further including rotating a plurality of louvers disposed in a ducted fan outlet opening between an open position, a closed position, and any position between the open position and the closed position to control a direction of movement of the aircraft. 12. An aircraft comprising: an inlet opening of a ducted fan formed in a surface of the aircraft;a door having a diameter the same as or larger than a diameter of the inlet opening; andan actuation system including a first arm and a second arm coupled to the door, the first arm and the second arm carried by a moveable carriage to move the door between a first position in which the door is disposed over the inlet opening and a second position in which the door is disposed over the surface of the aircraft and outside of a diameter of the inlet opening, the door oriented substantially perpendicular to a direction of an axis of the inlet opening in the first position and the second position, the carriage being moveable along a linear path, a first end of the first arm pivotably coupled to the door a second end of the first arm slidably coupled to a track, and an intermediate point on the first arm between the first end and the second end pivotably coupled to the carriage. 13. The aircraft of claim 12, wherein a third end of the second arm is pivotably coupled to the door and a fourth end of the second arm is pivotably coupled to the carriage. 14. The aircraft of claim 12, wherein a first section of the track is aligned with the direction in which the door is to move, and a second section of the track oriented perpendicular to the first section of the track, such that when the second end of the first arm slides along the second section of the track, the first arm rotates and causes the first end of the first arm and the door to move along an arcuate path. 15. The aircraft of claim 12, wherein the first and second arms extend through a slot in the surface of the aircraft. 16. The aircraft of claim 12, wherein first and second arms are a first pair of arms, the first pair of arms coupled to a first end of the door, the actuation system further including a second pair of arms coupled to a second end of the door opposite the first end of the door. 17. The aircraft of claim 12, wherein the actuation system further includes an actuator to move the carriage along the linear path.
