FACILITIES AVAILABILITY AND REQUIREMENTS FOR FABRICATION OF CASE SEGMENTS AND CLOSURES FOR LARGE SOLID PROPELLANT ROCKET MOTORS
Abstract
An investigation is reported of current industry capability for fabricating case segments and closures for large segmented solid propellant rocket motors. The capability of industry to fabricate cylindrical case segments using roll and weld technique, machined ring forging and power shear spinning is presented. For closure fabrication, the capability of industry to fabricate closures by spinning, explosive forming and welding is presented. Because of the limited technology currently available with more advanced fabrication techniques such as strip lap, fiberglass winding and cryogenic stretch forming, these processes could not be considered for immediate use on a large motor development program. The current capabilities of industry are further broken down to cover available vertical lathes, horizontal lathes, heat treat facilities, expandable mandrels, forged ring facilities, power shear spinning, welding, roll formers and flat plate production. Tables are presented which summarize the availability and requirements of facilities, cost and lead time to obtain the capability for four motor diameters; 100, 136, 156 and 200 inches diameter.
