A STUDY OF METHODS FOR EXTENDING FATIGUE LIFE OF CATAPULT ACCUMULATORS,

Abstract

This study was made to determine if the fatigue life of a steam accumulator can be extended by any of a number of methods. Six separate studies investigate analytically or logically the possible methods. As discussed where appropriate, some methods can be completely evaluated only by both studies and test data. The problem in accumulator design is that the observed fatigue life as manifested by cracking has been found to be less than the calculated fatigue life. Inspection of accumulators in fleet service has revealed extensive cracking near the manhole and near the nozzles. The accumulators which are installed at N.A.T.F., Lakehurst, New Jersey have had severe cracking at the head shell junction and at some nozzles. Almost all cracking has occurred on the inside surfaces. (Author)
