Title: RN Type 42 Batch 1 & 2 non modified air intakes
Post by: justboatonic on July 21, 2019, 06:55:52 pm
I have another question regarding, in particular, HMS Newcastle but also the early T42 B1 & 2 non modified air intakes build.
Hopefully the attached pics of the ship and model build will help to explain the question.
On the B1 & 2, the non modified air intakes butt upto the superstructure and serve almost as another deck. In this pic, you can see a couple of crew members stood on top of the intakes.

The model build shows a little better.(https://i.ibb.co/1ncrQMv/Foremast2.jpg) (https://ibb.co/X4H7LD2)

My question is, how did the crew access the deck on top of the air intakes? All the pictures I have do not show any doors on the next higher deck superstructure and none show any steps or stairway from the deck immediately below the Scot Domes or Optical Lookout Sights level.
Does anyone have any pictures or planned layout showing steps or stairway?
Thanks in anticipation.

There appears to be a doorway under the dome platform and a short stairwell to the top of the air intakes (1st photo)
Also a walkway heading ford'?

I thought that as well Captain (in the first picture of Newcastle) and this is the only picture I can find that suggests there's some form of stairway and, there doesnt seem to be any other access methods ie doors either side of the mast base or, up \ down ladders on the sides of the intakes.
Would be good if I could get any other verification though.

Thanks for the additional pics but they dont show crew access from the optical lookout sight deck to the deck space on top of the unmodified air intakes.

Well, we'll keep searching for the definitive answer but I've almost convinced myself there will be a short stairwell between the two. Maybe 5 or 6 steps angled to suit  {:-{

Hello,
From memory ,I served on Exeter and Cardiff, there were a few rings of a vertical ladder to get up to that deck, there was never much up there as the deck in bolts to get the engines out.

Paul

Hi. Thanks for the info for which I am very grateful. I just didnt want people to think I was after pictures of the deck under the Scot Domes or the optical sights etc and them go off looking for such.
From the pictures Ive found and others, its pretty clear there's a way up there!

What D108 said regarding the three/four rung vertical ladder. The deck was two bolted soft patches, which when removed accessed the Olympus Plenum Chambers and the Downtakes. The Splitter boxes (long sections of trunking with perforated vanes, which helped steady the air flow) would be removed, followed by a large box bolted to the front face of the Engine Module, called a Cascade Bend. This contained a 90 degree set of guide vanes, which altered the intake air flow direction from vertically down to horizontally aft, into the Engine Air Intake.
Guide rails were fitted, and the Engine lifted out. 
I seem to remember that when operational, the area served as a convenient storage space for Wicker Fenders.
Nice Model by the way, following your progress with interest.
