Abstract

A method and apparatus for deploying a group of panels. An apparatus comprises a group of panels in a folded configuration against a side of a spacecraft, a group of flexible members connected to the group of panels, and an interface system associated with the group of panels and the group of flexible members. The interface system is configured to move the group of panels from the folded configuration to a deployed configuration when the group of flexible members is extended from the spacecraft.

First claim

What is claimed is:

1. An apparatus comprising:
a panel in a folded configuration within a side of a spacecraft, wherein the panel includes a solar array comprising:
a first set of solar modules configured to be folded along a longitudinal axis; and
a second set of solar modules configured to be folded along a diagonal axis to form the folded configuration for the solar array;

a flexible member connected to the panel; and
an interface system associated with the panel and the flexible member, wherein the interface system is configured to move the panel from the folded configuration to a deployed configuration when the flexible member is extended from the spacecraft.

2. The apparatus of claim 1 further comprising:
a spool within a housing of the spacecraft, wherein the flexible member is configured to be wound on the spool.

3. The apparatus of claim 1 , wherein the interface system comprises:
connectors associated with the panel and the flexible member, wherein each connector in the connectors comprises a channel and is configured to attach to a panel in the panel; and
a group of engagement structures associated with the flexible member, wherein an engagement structure in the group of engagement structures is configured to engage with a corresponding connector in the connectors to move the panel in the panel from the folded configuration to the deployed configuration.

4. The apparatus of claim 1 , wherein the panel is connected to the spacecraft by a number of contact points.

5. The apparatus of claim 1 , wherein a panel in the panel is selected from one of a solar array, an antenna, and a drag device.

6. The apparatus of claim 1 further comprising:
a steering system configured to steer the panel in space.

7. The apparatus of claim 1 , wherein the interface system holds the panel substantially flat when the panel is in the deployed configuration.

8. The apparatus of claim 1 further comprising:
a housing of the spacecraft, wherein the panel is located against a number of sides of the housing when the panel is in the folded configuration; and
a number of doors configured to cover the panel located against the number of sides of the housing in the folded configuration and open such that the panel are moved from the folded configuration to the deployed configuration.

9. The apparatus of claim 1 , wherein the flexible member is comprised of structures with a cross-sectional shape selected from at least one of a round shape, a triangular shape, a rectangular shape, an irregular shape, or a hexagonal shape.

10. The apparatus of claim 1 further comprising:
a deployment mechanism configured to extend the flexible member from an interior of the spacecraft to an exterior of the spacecraft such that the panel move from the folded configuration to the deployed configuration.

11. The apparatus of claim 4 , wherein the deployment mechanism comprises at least one of a torsion spring or a motor within a housing of the spacecraft.
