'T-END CLOSURE STUDY FOR POLARIS A-3 ROCKET MOTOR CASE
Abstract
Design studies were begun of the aft dome section of the Polaris A-3 rocket motor case with the following objectives: (1) analyze the magnitude of stresses and stress distribution around the port openings; (2) determine structural requirements for port reinforcement and design optimum reinforcement for the stress pattern; (3) investigate use of a more ductile type of Al alloy for aft cluster fitting; (4) analyze shape of aft cluster and recommend shape which will reduce bending stress under pressure to a minimum; and (5) develop optimum flexible bond between Al cluster fitting and fiber glass chamber. Theoretical computations were made of stresses at port openings. (Author)
