  2. Outline • Background • Concept Description • Manufacturing Approach • Transition to Fleet • Summary

  3. AEM/S on USS Radford

  4. BACKGROUND • Half scale DDG Mast • Composite Structures

  5. ATD PAYOFFS • SOLVES PROBLEMS • Sensor Performance • Blockage • False Targets • Sensor Downtime • Affordable Signature Control • Topside Weight Limitations • Life Cycle Costs • Sensors • PCMS • ENABLES NEW TECHNOLOGY • Embedded Sensors • Planar Arrays • Low Observable ShipSignatures 3.696.448

  6. ADVANCED ENCLOSED MAST/SENSOR AEM/S

  7. TAILORED MATERIAL SYSTEMS

  8. Manufacturing Process RESIN INJECTION PORT RESIN INJECTION PORT DISTRIBUTION MEDIUM PEEL PLY DRY FABRIC CORE MATERIAL VACUUM PORT DRY FABRIC VACUUM BAG VP PEEL PLY MOLD SURFACE Seemann Composite Resin Infusion Molding Process (SCRIMP): • Near Autoclave Laminate Quality At Shipyard Prices • Extremely Low Void Content Laminate • High Fiber to Resin Volume Ratio = High Strength to Weight

  9. SCRIMP = Cost Effective Advanced Composite Structures

  10. FABRICATING THE STRUCTURAL MAST

  11. The AEM/S Experience – Fiber Reinforcement & Core Lay-up For A Deck Cloth Lay-up On Mold Core Laid On Cloth Core Laid On Cloth Cloth Lay-up On Core

  12. The AEM/S Experience – Fiber Reinforcement & Core Lay-up For The Mast Panel Laminated & Mold Rotated Cloth Lay-up In Full-Round Mold Lay-up For Sixth Side Panel Ring Girders Laminated In-Place Ring Girder Installation Lower-Half Removed From Mold

  13. The USS Radford AEM/S Mast Stepping Ceremony

  14. AEM/S Fleet Transition to LPD 17 Advanced Composite Mast on USS Radford • Successful ONR Funded Advanced Technology Demonstration (ATD) project • Rapid Transition from R&D to New Construction • Example of what can be Accomplished when the Navy and Private Industry Work Together Transition LPD 17

  15. Integrated Topside Goal
