Abstract:

The structural integrity of the motor case of a five-inch gun launched projectile is examined as a function of case thickness and maximum launch acceleration. The analysis techniques developed in a previous study of the buckling failure of a three-inch projectile motor case are applied to the five-inch case. Survivability curves are presented for case thicknesses of 0.09 in., 0.10 in., 0.12 in., 0.15 in., and 0.19 in. and a maximum launch acceleration of 7,000 gs. The 0.19 in. case under 6,000 gs is also examined. Both bonded and unbonded propellants are considered.
