DDG(X) Power and Propulsion Risk Mitigation
Abstract
In accordance with the FY 2020 NDAA, DDG(X) shall execute land based testing to reduce the technological and integration risks of the propulsion system. This effort will execute risk mitigation efforts for the DDG(X) Integrated Power System (IPS) selected and specified during design and analysis, including prototyping and testing in and Integrated Power and Energy Test Facility (ITF) that successfully demonstrates performance in a suitably realistic environment necessary to mitigate the technology risk. DDG(X) is initiating a phased systems engineering approach where risk is incrementally reduced to the necessary level to support performance of follow-on design and construction activities. This four-phased testing and risk reduction approach builds assurance that the IPS system can be installed and activated efficiently by the shipbuilder with performance characteristics that are well understood. Phase 1 (Digital Engineering) includes establishing a description of the components and system non-real-time models that are needed for the DDG(X) effort initiating the IPS digital engineering effort. This ensures requirements, specifications, and other important factors that determine intended use and performance bounds are defined. Phase 2 (Surrogate Testing) employs refined digital models and full-scale integrated surrogate components that functionally represent the intended DDG(X) power and propulsion system for testing at ITF. These models and surrogates support the build specification and guide the connection of equipment and interfaces at the ITF. Phase 3 (Tactical Hardware Testing) develop and transition ITF to the DDG(X) Land Based Engineering Site (LBES), builds a full-scale tactical representation of the shipboard power and propulsion system. Phase 4 (Shipboard Test & Activation) conducts shipboard integration testing of the power and propulsion system with other ship systems to confirm performance as specified in the contract requirements and interoperability at the platform level. The development of the Integrated Power and Energy System Test Facility (ITF) at NSWCPD for DDG(X) will be transferred after FY21 from this PE to the Electric Ships Program (PMS 320) funding line (PE0603573N/PU 2471) as the program office responsible for DDG(X) power and propulsion system execution.
