Abstract
A rocket motor extendible nozzle 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 membrane that is constructed by joining the two longitudinal edges may be collapsed for stowage with vastly reduced overall length, maximum diameter, and with substantially increased rigidity in comparison with the fully deployed unit. In the stowed condition, the material comprising the aft portion of the membrane is situated in multiple layers within the forward portion so that deployment is induced by forward-to-aft gas flow of the rocket motor within the cone.
