Unmanned aerial vehicle
The present invention relates to an aircraft with a surveillance system characterized in that the direction of flight towards a target is achievable by shifting the center of gravity of the vehicle towards the target. The center of gravity is shifted towards the target by pointing the surveillance system at the target.
1. An aircraft, comprising:
a surveillance system, said surveillance system being operably linked to said aircraft such that pointing said surveillance system towards a target results in a change in a center of gravity of said aircraft by a displacement of a mass via a weight-shifting apparatus and results in said aircraft being repositioned over said target, wherein said surveillance system is a camera, wherein said camera can move in 360 degrees.
2. The aircraft of claim 1 , wherein said aircraft comprises at least two sets of rotary wings which are able to rotate in a contra-rotary manner.
3. The aircraft of claim 1 , wherein said mass comprises said surveillance system.
4. The aircraft of claim 1 , wherein said aircraft comprises a support structure, wherein said support structure is freely rotatable around a body of said aircraft.
5. The aircraft of claim 1 , wherein said weight-shifting apparatus comprises a support structure of said aircraft.
6. The aircraft of claim 1 , wherein said aircraft has at least one sensor to determine and/or maintain altitude.
7. The aircraft of claim 1 , wherein said weight-shifting apparatus comprises an element which extends from said aircraft.
8. The aircraft of claim 7 , wherein said element is operably linked to an auxiliary drive unit at its proximal end and said surveillance system at or near to its distal end.
9. The aircraft of claim 8 , wherein said element is configured such that in its resting configuration said element hangs substantially vertically, or wherein said element is configured such that in its resting configuration it is offset from vertical.
10. The aircraft of claim 1 , wherein said surveillance system can be independently maneuverable in its housing.
11. The aircraft of claim 10 , wherein said surveillance system is self-righting to provide an upright image to an operator.
12. A method of controlling the direction of flight of an aircraft, comprising:
shifting a center of gravity of said aircraft via a weight-shifting apparatus such that said aircraft changes an angle of flight to move said aircraft towards said shifted center of gravity, wherein said weight-shifting apparatus is operably linked to a surveillance system such that movement of said surveillance system directly causes said shift in said center of gravity of said aircraft, wherein said surveillance system can move in 360 degrees.
13. The method of claim 12 , wherein said center of gravity can be displaced on a real-time basis towards a target according to an operator's selection of said target.
14. The method of claim 12 , wherein controlling the aircraft is achieved by weight-shifting apparatus extending from said aircraft.
15. The method of claim 14 , wherein said surveillance system is attached to said weight shifting apparatus.
