ABSTRACT:
A method of and apparatus for forming with a minimum of labor, by explosive forming means, an automatically extendible auxiliary nozzle member or exit cone for a rocket motor, the member having tapered sinusoidal flutes with the stresses and thicknesses thereof being uniform whereby, when deployed, the resulting form of cone can be predicted with accuracy, and stresses being created such as to build a spring bias therein so that the member is bistable, that is, stable in both the stowed position and in the deployed position.
