Abstract

A system for imparting linear momentum transfer may include a catching mechanism of a target space vehicle and a tether that is configured to impart a linear momentum transfer from the tether to the target space vehicle. The tether may be fixedly or detachably connected to a Kinetic Energy Storage and Transfer (KEST) vehicle that maneuvers and potentially retrieves the tether. Alternatively, the tether may be separate from the KEST vehicle and may be retrieved by a suitable retrieving mechanism, such as a robotic arm.

First claim

The invention claimed is:

1. A system, comprising:
a Kinetic Energy Storage and Transfer (KEST) vehicle comprising circuitry and a plurality of thrusters;
a tether operably connected to or retrievable by the KEST vehicle, the tether comprising a contact mechanism; and
a target space vehicle comprising a catching mechanism configured to receive the contact mechanism of the tether, the catching mechanism comprising webbing of sufficient length, width, weaving, and material such that the contact mechanism is traveling at a same speed as the target space vehicle before or by the time the contact mechanism rips through some or all of the webbing, wherein
the KEST vehicle is configured to position the tether for contact with the target space vehicle, and
the tether is configured to bend after the contact mechanism of the tether makes contact with the catching mechanism of the target space vehicle, and as the bend progresses, the target space vehicle speeds up and incremental sections of the tether where the bend is forming slow down, thereby transferring linear momentum of the tether to the target space vehicle.

2. The system of claim 1 , wherein the target space vehicle further comprises:
a plurality of thrusters; and
circuitry configured to receive a beacon signal from the tether, process the beacon signal, determine adjustments for the target space vehicle, and fire one or more of the plurality of thrusters such that the catching mechanism is maneuvered to make contact with the contact mechanism of the tether.

3. The system of claim 1 , wherein the catching mechanism further comprises:
a pair of tangs that are attached to the webbing and form a “V”, wherein
the contact mechanism of the tether is configured to enter an open end of the “V” and to tear the webbing towards a closed end of the “V”.

4. The system of claim 3 , wherein the catching mechanism further comprises a support member connected to the tangs at one end and connected to the target space vehicle at another end.

5. The system of claim 4 , wherein the connection between the support member and the target space vehicle is achieved via an attachment member configured to release the catching mechanism from the target space vehicle.

6. The system of claim 1 , wherein the contact mechanism comprises a hook.

7. The system of claim 1 , wherein the catching mechanism further comprises:
one or more support mechanisms; and
at least two pivot points connecting a support mechanism of the one or more support mechanisms to a body of the target space vehicle, to another support mechanism of the one or more support mechanisms, or to the catching mechanism, wherein
the one or more support mechanisms are configured to move from an orientation that is perpendicular to a trajectory of the target space vehicle to an orientation that is parallel to the trajectory of the target space vehicle after the catching mechanism of the target space vehicle makes contact with the contact mechanism of the tether.

8. The system of claim 1 , wherein
the tether is retrievable by the KEST vehicle, and
the tether further comprises a retrieval mechanism by which the tether can be retrieved by the KEST vehicle.

9. The system of claim 8 , wherein the retrieval mechanism comprises a ring shape or an elliptical shape.

10. The system of claim 1 , wherein the tether further comprises a beacon configured to emit a beacon signal that may be received by the KEST vehicle, the target space vehicle, or both.

11. The system of claim 10 , wherein the tether further comprises:
a power source configured to power the beacon;
a charging connector; and
a conductor operably connecting the power source to the charging connector.

12. The system of claim 1 , wherein the tether is tapered such that the tether becomes progressively wider from an end proximate to the contact mechanism to an end opposite the contact mechanism.

13. The system of claim 1 , wherein the circuitry of the KEST vehicle is configured to receive a beacon signal from the tether, process the beacon signal, determine adjustments for the KEST vehicle, and fire one or more of the plurality of thrusters such that the KEST vehicle can intercept the tether.

14. The system of claim 1 , wherein the tether is retrievable by the KEST vehicle and the KEST vehicle further comprises:
a robotic arm configured to retrieve an end of the tether.

15. The system of claim 1 , wherein the KEST vehicle further comprises:
a docking station configured to secure the tether to the KEST vehicle; and
a charging port configured to receive a charging connector of the tether and provide power to the tether.

16. The system of claim 1 , wherein the tether has a length of at least a mile.
