DEVELOPMENT AND FABRICATION OF HIGH STRENGTH SIMULATED ROCKET MOTOR CASES BY CRYOGENIC STRETCH FORMING PROCESS.
Abstract
The ARDEFORM cryogenic stretch forming process is shown to be a practical and valuable means for the fabrication of large diameter rocket motor cases. The cryogenic stretch forming process provides for: Incorporation of elliptical head shapes without the usual limitation associated with equipment size; Fabrication is accomplished by relatively simple processing; High strengths can be achieved with readily available materials. Current limitations of the cryogenic stretch forming process are associated with the application of previously determined processes to the fabrication of details for large diameter devices. Limiting areas include: Determination of detailed designs commensurate with current material forming techniques; Refinement of techniques for applying satisfactory weld beads in thick-walled vessels.
