Abstract
A self-erecting structure, including a plurality of unexpanded convoluted bellows means joined together to define an enclosed ring having an interior closed path, along with means for expanding the path. The means for expanding the path include a quantity of propellant contained within the interior closed path in an amount capable of expanding the plurality of bellows to significantly increase the size of the ring upon ignition of the propellant and ignition means for igniting the propellant upon receipt of a command.
