NOVELTY - The SDDS has flexible frame which supports at least one flexible sheet. The flexible sheet frame is twistable into at least two loops that are foldable into overlapping configuration.

USE - SDDSS for use in e.g. spacecraft, satellites.

ADVANTAGE - Reduces or eliminates he need of pyro-active or heavy device has to be brought on board the spacecraft for deploying the space structure. Allows the deployed flexible sheet surface higher than the case when SDSS is rigidly linked at the short distance from carrier structure. Ensures a reliable unfolding of deorbiting structures in zero gravity. Provides the strain energy provoking the deployment without the need of addition of energy to the system. Eliminates the issues around successful unfolding known from other technical solutions as the frame unfolds automatically without using external energy for unfolding by using the accumulated strain energy in stressed configuration. Ensures that deorbiting space structure can be efficiently folded without intervention of active unfolding device.
