ABSTRACT:
A controlled thermal expansivity structure whose length along a given axis of the structure and thermal expansivity in the direction of the axis, i.e. total change in length in response to a given temperature change, are independently adjustable in a manner which permits adjustment of the structure in length while maintaining its thermal expansivity constant and adjustment of the thermal expansivity of the structure while maintaining its length constant. The range of thermal expansivity adjustment may include zero expansivity to permit adjustment of the structure to dimensionally stable mode. The described structure is a load-bearing strut with end fittings which are adjustable to vary the length and thermal expansivity of the strut.
