We present a grounded optimal type of transformable-volume structures’ (TVS) basic surface and the developed mathematical model of its transformation into a compact form. Optimal geometric parameters of a conical type TVS were determined. The parameters of stresses distribution in a structure’s shell at successive stages of transformation was modeled and kinetics of a thinwalled conical TSV unfolding process was studied. Quality criteria of permanent joints of the transformable thin-walled metal shells were determined and the technological equipment for their manufacture and laboratory tests samples was designed.
