BISMARCK | Cooling water inlets – 1/100th scale | Part 2

The following pictures show my personal reconstruction of the cooling water inlets and how they could have worked. Beware: Eare human est.

Reconstructed and schematic flow pattern for
forward speed. Blue = cold, red = warm.

Flow pattern stern first.

Flow pattern bow first.

Bilge keel and inlets.

Reconstructed and schematic flow of cold water (blue)
and warm water (red). When traveling stern first cold water
flows thru the rear small inlets into the sea chest.

Guide plate (center) seperating the large and small inlet.

Small inlet for reverse speed and large inlet for forward speed.

BISMARCK | Cooling water inlets – 1/100th scale | Part 1

My long term project is a static replica of the German battleship BISMARCK. This time I will focus on the cooling water inlets for the turbines.

Reconstruction of the sea chest:
Y-shaped inlets for forward and reverse speed.

Cut-out in the hull for installing the sea chest.

4mm-balsa plating and glass fibre coating.

Dry fitting of the inlet made from styrene.

Test fitting.

Adjusting the fit was done with files.

Testing the inlet: it actually works very well!

I painted the hull flat black because it is
visible from outside.
