RISSpherical Acrylic Plastic Hulls Under External Explosive Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: NEMO-type acrylic spherical hulls have been subjected to underwater explosions in order to determine their resistance to hydrodynamic impulse loading. Six 15-in. OD and one 66-in. OD spheres ...
Spherical Acrylic Pressure Hulls for Undersea Exploration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exploratory phase of the research program into the applicability of acrylic to the construction of spherical pressure hulls for undersea exploration has been completed. The findings show ...
Effect of Bubble Inclusions on the Mechanical Properties of Cast Poly-Methyl Metacrylate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bubble inclusions present in cast acrylic plastic generally degrade the mechanical properties of the material. To evaluate the effect of bubbles on the mechanical strength of acrylic plastic, ...
Critical Pressure of Conical Acrylic Windows Under Short-Term Hydrostatic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study has been conducted to determine the critical pressure of conical acrylic windows under short-term hydrostatic loading. Conical windows with 30, 60, 90, 120, and 150 deg ...
NEMO Type Acrylic Plastic Spherical Hull for Manned Operation to 3000 ft Depth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: NEMO Mod 2000 acrylic plastic pressure hull assembly represents the latest addition to the NEMO hull series represented by NEMO Mod 600 and 1000 hull assemblies. The 66 in. OD × 58 in. ...
Deep Submergence Spherical Shell Window Assembly With Glass or Transparent Ceramic Windows for Abyssal Depth Service
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A total of 20 spherical shell windows with R0 = 4 in., Ri = 3 in., and 150 deg included spherical angle have been pressure tested under static and dynamic loading conditions. The tests ...
Spherical Sector Windows With Restrained Edge for Undersea Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new concept for the mounting of spherical sector windows has been experimentally evaluated under short-term, long-term, and cyclic pressure loadings. The new mounting concept requires that the ...
Hyperhemispherical Viewports for Undersea Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hyperhemispherical windows with included spherical angles in the 260–270 degree range have been fabricated from acrylic plastic and glass for a variety of undersea applications. When seated in ...
Performance of Photovoltaic Cells in Undersea Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Photovoltaic solar cells can serve as a reliable source of electric power for electronic instrumentation in temporarily or permanently submerged marine systems in the form of bottom installations, ...
Effect of Temperature and Flange Support on Critical Pressure of Conical Acrylic Windows Under Short Term Pressure Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Temperature and the seating arrangement in the flange have a significant effect on the critical pressure of conical acrylic windows. Over 400 acrylic windows with 90 deg conical angle were ...
