A retractable environmental seal for use in sealing the opening of the exit cone for a rocket nozzle is described. A diaphragm-like cover having a central region adapted to be seated in sealing relation with the periphery of the opening is discussed. Radially extended failure zones for facilitating a pressure-induced rupture of the cover, and a plurality of angularly spaced tension springs connected with the peripheral portion of the cover are characterized.
