Abstract

A method and system for supporting an airborne vehicle in space over a predetermined location and for an extensive period, comprises coupling the airborne vehicle by cables to a plurality of unmanned aircraft each having its own propulsion system; controlling the unmanned aircraft to fly in circular orbits at equally-spaced angles around the airborne vehicle while coupled to the airborne vehicle, to tension the cables and thereby to support the airborne vehicle in space over the predetermined location; and supplying the unmanned aircraft with energy from an external source to maintain the unmanned aircraft in flight over an extended or indefinite period of time.

Claims

1. A method of supporting an airborne vehicle in space over a predetermined location and for an extensive period, comprising:

coupling the airborne vehicle by cables to a plurality of unmanned aircraft each having its own propulsion system;

controlling the unmanned aircraft to fly in circular orbits at equally-spaced angles around the airborne vehicle while coupled to the airborne vehicle, to tension the cables and thereby to support the airborne vehicle in spaced over said predetermined location;

supplying the airborne vehicle, while supported in space over said predetermined location, with energy from an external source; and

transferring energy from said airborne vehicle to said unmanned aircraft to maintain the unmanned aircraft in flight over an extended or indefinite period of time.

2. The method according to claim 1, wherein said unmanned aircraft are electrically propelled and are supplied with electrical energy from said external source.

3. The method according to claim 2, wherein said electrical energy is supplied to the airborne vehicle from a microwave transmitter located on the ground.

4. The method according to claim 2, wherein said electrical energy is supplied to the airborne vehicle from solar cells located on the airborne vehicle and transmitted to the unmanned aircraft via said cables.

5. The method according to claim 2, wherein said electrical energy is supplied to the airborne vehicle from a power plant located on the ground and transmitting power to the airborne vehicle via a further cable.

6. The method according to claim 2, wherein said electrical energy is supplied to the airborne vehicle from a laser located on the ground.

7. The method according to claim 1, wherein there are at least three of said unmanned aircraft coupled to said airborne vehicle.

8. The method according to claim 1, wherein the unmanned aircraft support the airborne vehicle at an altitude of at least 50,000 feet but less than 200,000 feet above sea level.

9. A launching facility for launching an airborne vehicle according to claim 1, comprising a circular runway for the unmanned aircraft, and a central bay for the airborne vehicle.

10. A system for supporting an airborne vehicle in space over a predetermined location and for an extensive period, comprising:

a plurality of unmanned aircraft, each coupled by a cable to the airborne vehicle;

control means for controlling the unmanned aircraft to fly a circular orbit at equally-spaced angles around the airborne vehicle while coupled thereto, to tension the cables and thereby to support the airborne vehicle in space over said predetermined location;

energy-supplying means supplying said airborne vehicle, while supported in space over said predetermined location, with energy from an external source; and

means for transferring energy from said airborne vehicle to said unmanned aircraft to maintain the unmanned aircraft in flight over an extended or indefinite period of time.

11. The system according to claim 10, wherein said unmanned aircraft include electrical propulsion devices and means for supplying said devices with electrical energy from said external source.

12. The system according to claim 11, wherein said means for supplying electrical energy comprises a microwave transmitter located on the ground.

13. The system according to claim 11, wherein said means for supplying electrical energy comprises solar cells located on the airborne vehicle for generating electrical energy transmitted to the unmanned aircraft via said cables.

14. The system according to claim 11, wherein said means for supplying electrical energy comprises a power plant located on the ground and supplying power to the airborne vehicle via a further cable.

15. The system according to claim 14, wherein said means for supplying electrical energy comprises a laser located on the ground.

16. The system according to claim 11, wherein there are at least three of said unmanned aircraft coupled to said airborne vehicle.

17. The system according to claim 11, further including a launching facility for launching said unmanned aircraft, comprising a circular runway for the unmanned aircraft, and a central bay for the airborne vehicle.
