ABSTRACT:
A rocket motor extendible nozzle, in a first embodiment of the invention, is made by folding a sheet stock (metal, etc.) development of a membrane in the form of a cone or conical frustum (with a straight meridian) in such manner that the aft or larger diameter region of the cone that is constructed by joining the opposed edges may have the aft portion collapsed for stowage in a single layer of fluted form contained between two planes perpendicular to the axis of the cone with reduced overall length, and the forward portion extensively folded for substantially increased rigidity in comparison with the fully deployed unit. A second embodiment of the invention differs from the first embodiment in the further development of the membrane such that the aft end of the cone may be collapsed for stowage in multiple layers with vastly reduced overall length while retaining the increased rigidity of the forward portion in the stowed condition. Deployment is induced by forward-to-aft gas flow of the rocket motor within the cone.
