Seaglider Program: 1,000 Meter Depth

Record for longest deployment and travel - using no propellers, it travels silently
It moves forward by changing its buoyancy - propelling it by sinking and rising
The black bladder inflates and deflates with oil to change the buoyancy
Project closed in 2018 after supplying
more than 125 Seagliders and 8 Deepglider
Transferred to another manufacturer I believe

Deepglider Project - 6,000 Meter Depth

In Collaboration With
U.W. Applied Physics and designer Jim Osse

The initial stock was too large a diameter to fit over the cross-slide.
I used our largest steady rest to machine a section down to fit over the cross-slide.
No photos of that setup, but a photo showing the minimum clearance that created.
I had to flood the cross-slide to prevent chips from getting caught under the stock.
Photo shows tool block with two tools, but of course I only had one installed each time.  
Machining a mandrel.
For wrapping with carbon fiber.
Stock following machining with steady rest.
Custom tool holder with two tools

Heavy stock was dicey in the steady rest.
It rumbled threatening to dance around.
So I machined minimum needed to clear.

I made mandrels for these tests

Didn't seem to survive as well as above mfr.

Sensors: Salinity - pressure - oxygen
There may be other sensors for the DOD

Prototypes I built and helped to design.
One is partially cutaway to show the inner chamber, insulation and bellows neck.

The neck design greatly increases the distance for heat to travel from outside to inside.
Three Prototypes - good for over a month of vaccine storage.
Two early commercial versions. One current ARKTEK commercial PVSD.
