  1. AMP

  2. Frame • Delrin • Neutrally buoyant • Stiff • Easily adaptable • Waterjet bulkheads • Modular • Longitudinal stiffeners • Maximize usable volume • Captive nuts for structural strength

  3. Struts • Welded Al 5086 • Anodized as single piece • Fairing attached with 6 #10 fasteners as shown

  4. Pressure Housing Design • 5 nominal bottle types • 3 with significant differences • 9 per AMP → adds up quickly • Design must be: • Robust • Easily Configurable • Cost Effective • Key Features • Fabricated from standard pipe • Uses a filament retention system • No dissimilar metals in contact • Parametric design can be rapidly adapted to generate new bottles

  5. Pressure Housing Design Filament Groove Double O-Ring Seal

  6. Lense Design Wiper module Copper anti-fouling ring Double face seal

  7. FEA Results • Results are worst case observed across all bottles • Camera electronics bottle housing is the limiting factor • Peak stress occurs in a low-risk area • Design depth was 100m, deployment depth will be less than 30m

  8. FEA Results

  9. Operational Performance • 1000 lb total mass • Approximately 115 gal envelope • 60 gallons of water → 480 lb • Rough performance estimates based on initial CFD analysis • Vmax= 3.4 kts in 25 seconds • 1.75 m stopping distance
