Newtsuit

From Wikipedia, the free encyclopedia
Atmospheric diving suit designed by Phil Nuytten
The Newtsuit has fully articulated,rotary joints in the arms and legs. These provide great mobility, while remaining largely unaffected by high pressures.

TheNewtsuit is anatmospheric diving suit designed and originally built byPhil Nuytten.[1]

The suit is used for work on ocean drilling rigs, pipelines, salvage jobs, and photographic surveys, and is standard equipment in many of the world's navies.[2][clarification needed]

This aluminum hard suit has fully articulated,[3]rotary joints in the arms and legs that give the pilot a great range of mobility.[4] These joints operate freely at high pressures. At the time the suit was constructed, it was the first of its kind in this regard. The pilot can control objects and handle tools with manipulator jaws at the ends of the arms. Although the suit is certified to 300 metres (980 ft), it has been tested to 900 metres (3,000 ft).[5]

The suit can be operated untethered, with a thruster pack that can be fitted to the suit. This allows mobility in mid-water.[1] The Newtsuit navigates with foot controls. The left foot provides vertical control, with the right foot providing lateral control.[3] Other equipment that can be attached includes twin video cameras, colour imagingsonar, and an AMS[clarification needed] suit monitor system that transmits information to the surface, such as CO2, HPO (high pressure oxygen), O2%, depth, temperature, and cabin pressure.[3]

Communication is achieved through digital voice/data transmission via water andumbilical cable.[3]

Emergency equipment

[edit]

In the event of an emergency, the suit is equipped with the following:[3]

Exosuit

[edit]

The newest generation of this type of suit is called the Exosuit, also designed by Phil Nuytten.[7]
