Abstract:

A description is given of the fabrication studies and tests to determine the material allowables for, together with a description of, subscale and full-scale filament- o nd sandwich rocket motor cases. The edgewise compression and smallscale sandwich-wall cylinder tests that were initiated to determine design values for sizing the subscale and full-scale sandwich rocket motor cases are summarized. The fabrication process used to build the sandwich- wall cylinders and subscale cases is described in detail, together with the associated mandrel-tooling development studies. Test results of the subscale motor cases are discussed and analyzed. A subscale case was built which exceeded the ultimate design pressure by 10 percent. A detailed stress analysis for the full-scale rocket motor cases is presented, together with design drawings of the motor case, nozzle, and internal insulation.
