ADAM Collapsible Truss System

The ADAM collapsible truss system from Able Engineering Inc., is, according to Tilbert [1] something of a simplification upon the earlier FAST mast system produced by the same company. The ADAM system is deployed by a rotating nut at the base, which swivels each bay in turn upon spherical hinges and causes it to spring into a rigid box, as shown by Figure 3-18. Each box is then stiffened and secured as the diagonal cross-ties become taut resulting in a space-proven and highly scalable structure, the longest example of which reached nearly 61 m.

ADAM boom deployment in progress. Notice that the deployed structure is immediately rigid. From
