Structural Analysis Status Report, 5-inch Guided Projectile

Abstract

Twelve rounds in various test configurations of the five-inch guided projectile were test fired to verify the motor case load and stress analysis so that a selection of wall thickness to support a sixty pound payload could be made. Analysis efforts previous to these tests had indicated that all motor cases with walls less than .190 would buckle and that the .190 wall motor case was marginal. None of the test motor cases buckled. All the motor cases with wall less than .190 inches experienced a reduction in length (permanent strain) indicating an imposed longitudinal stress in excess of the compression yield. This report presents the current thinking of the structure analysis effort and attempts to provide some guidance for future structural design of the guided projectile motor case.
