Titan (ubåd)
For alternative betydninger, se titan. (Se også artikler, som begynder med titan)
Titan, tidligere kaldet Cyclops 2, var en eksperimentel undervandsbåd, der imploderede den 18. juni 2023, mens den transporterede turister for at besøge vraget af RMS Titanic.
Undervandsfartøjet blev skabt og drevet af OceanGate. Titan var den første privatejede undervandsbåd med en påstået maksimal dybde på 4.000 m,[1] og den første færdige bemandede undervandsbåd med et skrog konstrueret af titanium- og kulfiberkompositmaterialer.[2][3]

The ability of carbon fibers to withstand repeated cycles of stress, especially compressive stress, under deep-sea pressures is not well understood, making it difficult to design safe hulls based on carbon fibers. The degrading effects of water absorption on the epoxy binding the carbon fibers in the composite should also be kept in mind in assessing the failure of Titan..."

Schematic providing overall dimensions of the Titan submersible designed and built by OceanGate. Titan is depicted in a side view, with the forward hatch to the left. The pressure hull consists of three major components: two hemispherical titanium end caps, joined to a cylindrical carbon fiber composite hull via titanium interface pieces which are bonded to the carbon fiber hull and bolted to the end caps. The composite hull and aft end cap are surrounded by a glass fiber composite shroud. There are two thrusters per side, one vertical and one horizontal. This drawing is to the scale of 1 pixel = 1 cm. The human figures, as drawn on the Pioneer 10 plaque and converted to silhouette to avoid issues with nudity, have been added for scale. According to the schematics on the plaque, the woman is 168 cm; the man is scaled to 174 cm accordingly.

The dimensions for the cylindrical carbon fiber hull were taken from stated design specifications in a news article published by CompositesWorld: Sloan, Jeff (May 10, 2017). "Composite submersibles: Under pressure in deep, dep waters". CompositesWorld.
According to the Titan specification sheet, the thrusters are Innerspace model 1002. Thruster dimensions are taken from the manufacturer's website: Model 1002 series electric thrusters. Innerspace Thrusters. and the profile was simplified for graphical purposes. News photographs of the Titan indicate the thrusters were mounted directly to the fiberglass shell without fairings, although an earlier version (the hull was rebuilt after 2020) may have incorporated fairings for the vertical thrusters, as shown in an Everett Herald news article: Davey, Stephanie (March 9, 2020).

The viewport is stated to be 15 inches in diameter and 7 inches thick. Petapixel states the diameter (presumably for the outside surface) is 21 inches, which clearly shows a domed surface: Growcoot, Matt (June 20, 2023).
