Objective:
The objectives of this project are to:
- Produce a TSA guidance document that incorporates collective shock analysis knowledge and practice,
to be issued by NAVSEA 05P1
- Document results in order to ensure a more technically robust and programmatically efficient shock
industry wide shock qualification via M&S on surface combatants
Summary:
HII-NNS, HII-Ingalls, and NSWC-CD 661 will collaborate to improve specifications and associated guidance on how industry should analyze systems to achieve shock qualification by analysis via TSA. NSWC-CD 661 currently has two NAVSEA 05P1 delegated approval authorities (DAA) who review and approve transient shock analyses but are also active R&D engineers. These two engineers will use their subject matter expertise to document, in great detail, what is required when performing TSAs. Additionally, HII-NNS and HII-Ingalls have engineers experienced in TSA and applying TSA methods to both surface ship and submarine combatant design and shock qualification efforts. HII engineers will collaborate with NSWC-CD 661 TSA DAAs to ensure alignment of shipyard specific rules, knowledge, and guidelines are included. Congruent efforts between all parties will ensure that topics that span from mesh sizing, to quality assurance, to how to determine quantities of interest, are appropriately evaluated and documented. Further, this effort will dovetail with a similar R&D task, funded by PMS 351, for submarines, and ensure that all lessons learned and guidance developed for submarines can be effectively leveraged for surface combatants.
Key Deliverables / Benefits:
This project will provide a TSA guidance document for surface combatants and presentations at workshops to showcase results.
