Advancing Ship Battle Damage Response by Integrating Distributed and Hull Systems Models

摘要

Mission altering hull damage experienced by Stark, Roberts, Tarawa, Princeton, Cole reminds us that the Navy Policy of Distributed Lethality requires ships to fight and 'fight-while-hurt.' Fighting while hurt in the context of Navy Policy of Total Ship Survivability requires immediate and continuous realtime readiness assessment and restoration of both distributed and hull systems to maximize available remaining combat systems sensing and firepower. Today's HM&E distributed systems that are designed and implemented with physics reference models are able to describe the damage to the systems. When mission altering hull damage occurs today's ships have few sensors capable of automatically detecting and describing transverse structure hull damage. Describing transverse structure loss is the primary factor required in the Navy provided shipboard Hull Structural Strength System (HSSS) / Intelligent Decision-aids (IDA) software. Reviewed are hull sensors tested aboard the ONR X-Craft and HSV-2 to monitor stress and hull fatigue. Required are hull / transverse structure failure sensors sufficiently accurate to automatically input the damage into the NSWC HSSS-IDA decision-aids. Applications of Finite Element Analysis and Virtual Reality techniques developed for ROKN post-damage analysis of Cheonan sinking in 2010 point to future hull damage analysis capabilities.
