Definitely some of the best Bourke Kitbashes I've ever seen, good work!

There's no such thing as "nothing left to draw" If you can down 10 pints and draw, you're doing alright by my standards

Not true, most of the intakes are indeed located in what you would call the "funnels" of a Burke along with the mixing rooms. Maybe that is what you ment by superstructure in this case.

The only intakes that are not located on the funnels are those for #1 generator which are above the aft entrance to the breaks and those for #3 generator which are located on the superstructure forward of the flight deck and are hard to see in profile.
A Burke regardless of flight has three service generators located in the same place. One aft as you descriped, one amidships and one forward. They are all GTGs.

Ooooooh...I can see that coming in handy. Thank you!
Do you mean close in location, or in size of the diesels?
Not a bad idea: if the Burke was designed as 3/4s of a Ticonderoga with 3 directors and 96 VLS cells, then this could be intended as 1/2 with 2 and 64.
Oh, I'm sold on the logic. My concern is that the easiest way to keep development costs down is to modify as little as possible of the standard Burke design; unfortunately, that makes for a very boring personal design!
Thank you....but I have to ask something rather important: what is COGOGL? Combined Gas or Gas Electric??
Thanks for all your help...it's much appreciated.
Thanks you! Although the credit belongs to the original artists, who did the really hard work...
Okay...I apologise for mangling a fine drawing, but I would like to get the location and role of the various intakes clear in my own mind:



Is this correct?

I'm guessing that either Group A or Group B feeds Generator #2, but which is it? And what is the other group for? Also, what is the role of the white panels on the forward funnel? Access panels?

Or...a photo I've just found suggests they are lockers of some description...fire-fighting gear? Rescue equipment?

You pretty much got it except the lockers. Those are ready service lockers for small arms and crew served weapons or in that particular case reloads for the chaff launchers.

as far as I understood, the intakes for the forward gas turbines are the ones listed as generator 1 in the image above. forward turbines would be that of the exhaust cooling, and gas turbine intakes for the aft engine room would be not visible on this side, but be on the other side of the funnel, in the lower superstructure. the maintenance pannels are indeed liferafts and possibly small arms lockers, as noted above, in the plans I have seen these are listed as emergency. IIRC, generator A is below the forward VLS, but I do not know where it's intakes and exhausts are, this is just from memory so I might be wrong.

shipright, not to prove wrong what is your expertise, but could you edit the burke drawing and show us what is where, preferable in the hull as well? I am curious how this is arranged.

I ask of you to prove me wrong. Not say I am wrong, but prove it, because then I will have learned something new.

Thanks for the info...if the location of the forward turbine intakes can be confirmed, that would help me enormously!

In the meantime, a final update before bed, incorporating the latest thinking:



Changes:

• The aft VLS has been reduced back to 32 cells
• One of the fire control directors has been deleted
• The aft engine room funnel has been resized
• The forward superstructure and funnel have been modified: the superstructure has been extended slightly at the break to incorporate an extra intake for increased airflow

This is probably the best I can come up with (at least at this moment in time) without more detailed information about the Burke's internal structure.

I have seen, but regrettably cannot disseminate, a layout of the gas turbine intakes and exhausts on a Burke. Like with other USN combatants, the gas turbine units themselves are removed directly vertically, through the intake plenums. Ace is correct; what is listed as intake for #1 generator is at least part of the intake area for the LM2500s in MMR #1. I assume this is one of the "mixing rooms" referred to above. These turbines, serving the starboard shaft, are (naturally) on the starboard side of the ship. Unlike a Spruance or a Ticonderoga, the exhaust trunks are not straight vertical; they take two sharp bends in order to stay on the centerline of the ship (this is forced, of course, by the SPY-1 layout). The intakes on either side of the second funnel serve MMR #2, and these are also served by a second mixing room that is on the port side of the ship. The port screw is, of course, powered by gas turbines on the port side of the ship. Presumably the considerably larger intake surface area on the forward mixing room is for servicing crew needs as well as SPY-1 cooling. Unless that's water cooled.

As usual, I'm making some of this up as I go, and no warranty is provided or implied.

No worries, I am wrong all the time

I haven't had to know where each individual vent went to and from since my warfare qualification a decade ago. I have worked on DDG Flight Is six of the last ten years, but I have never worked in engineering department so this is just what I remember from my boards and walking around the damn things for so long.

Here is my take visualized



This is a pick of the 3GEN intake near the helo control tower.



The mixing rooms probably are where the various exhausts combine. Now I never actually asked but I assumed they are called that because that's where the exhaust gases are mixed with outside air to cool them down before going out of the top. The outside air is generally much cooler so this reduces IR signature but its effectiveness depends on the weather. This combined with the bliss caps supposedly greatly reduced signature but the bliss caps (the black things at the top) are missing from the newer Burkes so apparently they didn't work well.

SPY, at least on the Burkes, is water cooled.

I thought the caps were merely radar-shielded by extended stack shells, but were still present within. Certainly they'd be a non-zero maintenance item, and I'd expect they would have been removed from other ships in the class if they were no longer wanted. It's hard to find lots of good, high-quality top-down photographs, but the diameter of the exhausts doesn't appear to have changed, either. Without that mixed cool air, the exhausts would not need to be as large as they are.
