Evaluation of New Aluminum Gas Cylinders for Use with the Swimmer Delivery Vehicle.
Abstract
A program was conducted to determine the basic performance characteristics for a limited number of new aluminum gas cylinders for use with the Swimmer Delivery Vehicle. This research consisted of five major tasks: virgin burst experiments, cyclic fatigue experiments, computer analysis of existing alternate design configurations, extended time low temperature creep experiments, and buoyancy experiments. It was concluded that the (specified) operating pressure was significantly higher relative to the observed cylinder burst pressures when compared to the operating pressure to burst pressure ratios normally encountered in diving gas cylinders. It was recommended, therefore, that the operating pressure be reduced to 1500 psig. It was further recommended that the cylinders be inspected for cracks every six months or 100 cycles due to the localized high stresses discovered in the end cap. (Author)
