Abstract

An aircraft can include a first wing and a second wing. The first wing can extend laterally from an aircraft body to a first tip, and the second wing can extend laterally from the aircraft body to a second tip. The aircraft can include a first end effector and a second end effector, each including a fore winglet and an aft winglet. The fore and aft winglets of the first end effector can be pivotably connected to the first tip. The fore and aft winglets of the second end effector can be pivotably connected to the second tip. The fore and aft winglets of the first and second end effectors can be independently operable. The first and second end effectors can be independently operable. A processor can be operatively connected to control movement of the fore and aft winglets of the first and second end effectors.

the aircraft being a kite.

2. An aircraft comprising:
an aircraft body including a wing, the wing extending laterally from the aircraft body to a tip; and
an end effector including a fore winglet and an aft winglet, the fore winglet and the aft winglet being pivotably connected to the tip, the fore winglet and the aft winglet being independently operable,
the aircraft being tailless.

3. The aircraft of claim 1 , wherein the fore winglet is different from the aft winglet.

4. An aircraft comprising:
an aircraft body including a wing, the wing extending laterally from the aircraft body to a tip;
an end effector including a fore winglet and an aft winglet, the fore winglet and the aft winglet being pivotably connected to the tip, the fore winglet and the aft winglet being independently operable; and
webbing, and the fore winglet and the aft winglet being connected by the webbing.

5. An aircraft comprising:
an aircraft body including a wing, the wing extending laterally from the aircraft body to a tip, the aircraft body being inflatable; and
an end effector including a fore winglet and an aft winglet, the fore winglet and the aft winglet being pivotably connected to the tip, the fore winglet and the aft winglet being independently operable.

6. The aircraft of claim 1 , wherein the fore winglet and the aft winglet are connected to the tip by a hinge.

7. The aircraft of claim 1 , further including one or more actuators, the one or more actuators being operatively connected to cause pivoting movement of the fore winglet and the aft winglet.

8. A system comprising:
an aircraft including:
an aircraft body including a first wing and a second wing, the first wing extending laterally from the aircraft body to a first tip, the second wing extending laterally from the aircraft body to a second tip; and
a first end effector including a fore winglet and an aft winglet, the fore winglet and the aft winglet being pivotably connected to the first tip, the fore winglet and the aft winglet being independently operable;
a second end effector including a fore winglet and an aft winglet, the fore winglet and the aft winglet are pivotably connected to the second tip, the fore winglet and the aft winglet being independently operable,
the first end effector and the second end effector being independently operable; and
webbing, and wherein the fore winglet and aft winglet of the first end effector and the second end effector are connected by the webbing; and

a processor operatively connected to control movement of the fore winglet and the aft winglet of the first end effector and the second end effector.

9. The system of claim 8 , further including one or more actuators operatively connected to the processor, the one or more actuators being operatively connected to cause pivoting movement of the fore winglet and the aft winglet of the first end effector and the second end effector.

10. The system of claim 8 , wherein the processor is configured to control the first end effector and the second end effector in a roll mode, wherein, in the roll mode, the processor is configured to:
control the first end effector such that the fore winglet is pivoted upward and the aft winglet is pivoted downward relative to the first tip; and
control the second end effector such that the fore winglet and the aft winglet are pivoted downwardly relative to the second tip.

11. The system of claim 8 , wherein the processor is configured to control the first end effector and the second end effector in a yaw mode, wherein, in the yaw mode, the processor is configured to:
control the first end effector such that the fore winglet and the aft winglet are pivoted upward relative to the first tip; and
control the second end effector such that the fore winglet and the aft winglet are pivoted downward relative to the second tip.

12. The system of claim 11 , wherein the fore winglet and the aft winglet of one of the first end effector or the second end effector are offset from each other.

13. The system of claim 8 , wherein the processor is configured to control the first end effector and the second end effector in a roll-yaw hybrid mode, wherein, in the roll-yaw hybrid mode, the processor is configured to:
control the first end effector such that the fore winglet and the aft winglet are pivoted upward relative to the first tip, wherein the fore winglet and the aft winglet are offset; and
control the second end effector such that the fore winglet and the aft winglet are pivoted downward relative to the second tip, wherein the fore winglet and the aft winglet are offset.

14. The system of claim 8 , further including a sensor, wherein the sensor is located onboard the aircraft, wherein the sensor is operatively connected to the processor, and wherein the sensor is configured to acquire sensor data about one of: the aircraft and an external environment of the aircraft.

15. The system of claim 14 , wherein the sensor is a wind speed sensor.

16. The system of claim 14 , wherein the processor is configured to control the first end effector and the second end effector based on the sensor data.

17. The system of claim 8 , wherein the processor is configured to control the first end effector and the second end effector autonomously.

18. The system of claim 8 , wherein the processor is configured to control the first end effector and the second end effector in response to remote control inputs.

19. A system comprising:
an aircraft, the aircraft being tailless, the aircraft including:
an aircraft body including a first wing and a second wing, the first wing extending laterally from the aircraft body to a first tip, the second wing extending laterally from the aircraft body to a second tip; and
