The lower viewport and CTD probe Detail view of the dive weight release mechanism and one of the LED light panels. The forward and downward view through the three ultra-wide angle acrylic viewports is unobstructed by structure or appendages, and illuminated by ten externally mounted high output LED lighting panels of 20,000 lumens each.
The submersible was designed by Graham Hawkes and Hawkes Ocean Technologies (HOT). It was originally ordered by Steve Fossett for an attempt on the Challenger Deep, to become the first solo dive there. [1] [2] Planning for the submersible started in 2000. [3] It was put on the order sheet in 2005, with a depth capability of 11,000 metres ...
The submersible features two robotic arms and can be fitted with mission-specific sampling and experimental gear. The plug hatch of the vessel is 0.48 m (1 ft 7 in) in diameter and somewhat thicker than the 2-inch (51 mm) thick titanium sphere pressure hull; [ 2 ] it is held in place by the pressure of the water above it.
LED power dissipation is modeled as a current source; thermal resistance is modeled as a resistor; and the ambient temperature is modeled as a voltage source. High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light – about 70% heat and 30% light. [1]
Ictineu 3 is a crewed submersible with a large semi-spheric acrylic glass viewport and is capable of reaching depths of 1,200 m (3,900 ft). Some submersibles have been able to dive to great depths. The bathyscaphe Trieste was the first to reach the deepest part of the ocean, nearly 11 km (36,000 ft) below the surface, at the bottom of the ...
Deepsea Challenger (DCV 1) was a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of the Challenger Deep, the deepest-known point on Earth.On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep.
