Abstract
A composite static structure formed of interdependent subcomponents, referred to as simple tetrahypars, combined to achieve an independent structural component or tetrahypar. Each simple tetrahypar has two rigid struts spaced along and extending perpendicular to a common axis of twist and lying in planes that intersect along the axis. The struts are connected by a torsion member, called a twister, that extends along the axis of twist. One strut of one tetrahypar is connected between one set of ends of the two struts of the other tetrahypar, and the other strut of the one tetrahypar is connected between the other set of ends of the two struts of the other tetrahypar. A structural component (or tetrahypar) of the type thus constructed may be combined in several ways with one or more other tetrahypars to form various tetrahypar structures, such as by joining tetrahypars at the points of connection (or vertices) between struts of the simple tetrahypars, by joining (or combining) along a strut of one tetrahypar coextensive or coinciding with a strut of another tetrahypar, by joining the midpoint of one strut of one tetrahypar with the midpoint of one strut of the other tetrahypar, and the midpoint of another strut of the one tetrahypar with the midpoint of another strut of the other tetrahypar, or by various combinations of the above.
