A retractable environmental seal for use in sealing the opening of the exit cone for a rocket nozzle was devised. The seal comprises a diaphragm like cover having a central region adapted to be seated in sealing relation with the periphery of the opening. It is characterized by radially extended failure zones for facilitating a pressure induced rupture of the cover. A plurality of angularly spaced tension springs is connected with the peripheral portion of the cover for retracting fractured segments of the cover from the opening subsequent to a pressure induced rupture.
