Abstract
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.
