Flexible and resilient masts are connected by flexible and resilient inner and outer spars, and flexible cords radially connect the spars. A flexible material is attached to the cords. The assembly is wrapped around a rotatable cylindrical drum in the structure's stored configuration. Each mast is flexible only about an axis lying parallel to the axis of rotation of the drum, and is otherwise rigid. Each mast is linear when extended and has a bending stress when deformed into a non-linear configuration, such as when wrapped around the drum. When the structure is in its stored configuration, a restraining device opposes the bending stress and another prevents the drum from rotating. Upon disengagement of the restraining devices, the stored bending strain energy forces the drum to rotate and the masts to extend into the deployed configuration and thereby unfurl the flexible material.
