Validation of new crack monitoring technique for Victoria class high-pressure air bottles / Ian Thompson, John R. MacKay. : D68-2/81-2014E-PDF
High-pressure (HP) air bottles are used in the Victoria class submarines for emergency air and displacing water in the ballast tanks during surfacing. The vital nature of these activities means that the integrity of HP air bottles is critical to safe operation. As such, measures must be taken to ensure fracture or leakage is avoided. Currently, the bottles are periodically inspected and damaged bottles are removed from service. This document covers the validation of the use of externally mounted strain gauges to monitor further growth of cracks of a limited size. Finite element analyses of experimental samples similar to air bottles were conducted using the same modelling techniques used by BMT Fleet Technology. The results of the finite element analyses were compared to experimental results. Digital image correlation (DIC) was used in the experiments and its use, associated challenges, and potential future uses are discussed.
