FIBERGLASS MOTOR CASE STUDY-POLARIS SECOND STAGE END CLOSURE

Progress was reported in resolving the problem involving the selection of an optimum winding pattern for the fiberglass motor case dome closures. It has been established that in any dome configuration the winding pattern and contour must be mutually compatible to minimize bending and inflection points. Furthermore, the contour must be such that subsequent deflections during hydrostatic loading will not effect the original shape to the point where serious bending and inflection points are encountered. With this in mind, a concerted effort was made to determine the significant parameters effecting these contours and the magnitude of these effects. (Author)
