EVALUATION OF FILAMENT-WOUND HIGH PRESSURE CYLINDERS FOR USE WITH THE MARK VI UNDERWATER BREATHING APPARATUS

摘要

A program was conducted to investigate the performance characteristics of experimental filament-wound cylinders for possible use with the Mark VI Breathing Apparatus. Magnetic effects experiments were conducted according to the procedures defined in MIL-M-19595B (OS). Cylinder strength properties were identified through: (1) virgin burst experiments, (2) cyclic fatigue experiments conducted under various environmental conditions, (3) exposure to ultraviolet light and thermal shock, and (4) impact-type damage tolerance experiments. Recommendations were formulated for the use, storage, and handling of the cylinders. Buoyancy trim and back-pack modifications were identified for the Mark VI Breathing Apparatus when used with the filament-wound cylinders.
