Abstract

Claims (14)

1. An aircraft wing assembly comprising:

a wing;

a ducted fan integrated within the wing;

inlet louvers and outlet louvers positioned on opposite sides of the ducted fan; and

an actuating mechanism that is configured to adjust at least the inlet louvers between an open position and a closed position,

wherein the actuating mechanism comprises (i) a plurality of bars spanning the ducted fan, wherein each bar has one pushrod that is connected to the inlet louvers by way of louver levers extending from the bar, (ii) a rotational actuator having two output shafts, and (iii) two rotatable members on opposite sides of the rotational actuator, wherein each rotatable member is connected to one of the two output shafts, wherein each rotatable member has a radial lever extending therefrom, and wherein the radial levers are respectively connected to the pushrods such that rotation of the rotatable members causes translation of the pushrods.

2. The aircraft wing assembly according to claim 1 , wherein the ducted fan is substantially horizontal.

3. The aircraft wing assembly according to claim 1 , wherein the inlet louvers and the outlet louvers are together configured to either prevent or limit a pressure compensation between a negative pressure prevailing above the wing and a positive pressure prevailing below the wing through the ducted fan in a cruising phase of the aircraft.

4. The aircraft wing assembly according to claim 1 , wherein the aircraft is fully autonomously controllable.

5. The aircraft wing assembly according to claim 1 , wherein each output shaft of the two output shafts is assigned to a respective one of the bars of the plurality of bars.

6. The aircraft wing assembly according to claim 1 , wherein each radial lever is connected to the respective pushrod by a link.

7. The aircraft wing assembly according to claim 1 , wherein each radial lever extends radially beyond a perimeter of the rotatable member to which the radial lever is connected.

8. The aircraft wing assembly according to claim 1 , wherein each radial lever rotates along with the rotatable member to which the radial lever is connected.

9. The aircraft wing assembly according to claim 1 , wherein the rotational actuator is positioned at a location between the rotatable members.
