CT Only: Fixing the Type S (Sulieman)

[Grav_Moped]

Fun thing is that the volume formula for a rhomboid pyramid (such as the Type-S) is a simple LWH/3 computation.

• 26 * 18 * 4.5 / 3 = 702m³ = 50.14 tons

Hmmm ... the dimensions seem to be a little ... on the small side ...



If you assume that you want to end up with 1400m³=100 tons as your answer for a single deck rhomboid pyramid design, you really want to have a 6m height at the aft end on the centerline (so as to fit a 3m high deck along most of the centerline).

• 1400*3/6 = 700

You then just need to choose fore/aft and port/starboard that when multiplied together come as close as possible to 700 (such as 70x10 or 35x20, for example).

• 35 * 20 * 6 / 3 = 1400m³ = 100 tons

EDIT: I realized that you're calculating the volume of a different object. Disregard.

Spoiler

I've done the math, and it's slightly more complex than that.
The pyramid is 25m (or so -- i am away from my notes) by 7.5m x 37.5m, with the corners clipped off where it's 24m wide.

Volume is (base area x height) ÷3. The base is not a 7.5m x 25m rectangle, it's a pair of 3.75m x 25m triangles with a common base (before clipping the cormers). Height is 37.5m

It works out to about 85Td, give or take.

I was just saying in the post that the classic Suleiman Class was the Adv.-0/ S-7 version, and some people might not accept his as the Suleiman Class, even though it's the fixed version. I thought that giving it another name it might stop some rants before they had a chance to get started.

Fair point.

That said, it's not a "new" design -- I consider it to be as close as reasonably possible to what was intended by the original illustration, deck plan outlines, and stated dimensions.* Somewhere in the game-design and publication process, they broke it by adding spaces and features to the deck plan which could not fit into its stated dimensions. I un-broke it, mostly. This is pretty much what I did with my Patrol Cruiser project a while back.

For differentiation, one could (and I may) refer to it as "Sulieman Revised" or something like that. But in-universe, it is exactly the same ship!

‐-------------
* replacing the transverse corridor in front of the drive bay with separate diagonal airlocks (and the ensuing modification to the landing gear) probably wasn't entirely necessary.

... and on taking a closer look at S7, once again this is a W.H. Keith illustration and layout that got messed up by changes to accommodate publication.

And this gives me a little insight into what the original layout for the Patrol Cruiser might have been (which is slightly different from what I worked out to replace the FASA deck plans).

Still in progress, but close to done.
AHL style, 1/2"=1.5m.
Still needs color key, scale declaration, and title block.
Note that the upper crawl space (locations 18 and 19) is only 1m tall.

EDIT: Just noticed I need to add the ceiling hatch in the drive room (it's only showing the floor hatch to the "drive-room bilge".

Fits on 8.5"x14" paper with 1/4" non-printing margins all around.

Second pass at the semi-final draft:
2a is still the computer.
8a is a full head with shower fixtures. (Staterooms have fold-away toilet/washbasin appliances.)
8b is a kitchenette area (oven, cooktop, sink, storage). It can be hidden by a roll-up door.
15: there are now two more "ship's locker" lockers, just behind the cockpit. None are full-height.

Maintenance access hatches to lockers and computer room?

S7, p5:
_ _ Maintenance Hatches: At some points, small, unobtrusive maintenance hatches have been placed in bulkheads to allow repair or service personnel access to machinery or equipment. Maintenance hatches are not commonly used; that i s to say, they stand closed and generally ignored nearly all of the time. Only rarely do crew and passengerseven recognizetheir existence.
_ _ Maintenance hatches are unpowered, and they lock with a common service key. On most commercial ships, one key fits all maintenance hatches and most officers and senior ratings have such a key. On military ships, such hatches are separately keyed, and only proper personnel have such keys.

To be airtight (forward "airlock") you presumably need iris valve or full hatch?
For regular use a sliding door?

You don't really need an airlock (double iris valves) between 8 and 13/14?

The cargo hold really needs a large hatch to load larger items, despite not being original?

There's no symbol for "locker door," so I made do. The computer room is normally not accessed. Maybe a regular hatch would be more appropriate.

I'm assuming the lockers in the cargo bay are airtight, but not as impenetrable as interior bulkheads.

You don't really need an airlock (double iris valves) between 8 and 13/14?

If there were any other seal-able compartment between 8 and 13/14, I'd be fine without them.
Mostly I'm overcompensating for the original's screwed up layout (11/13/15 -- open the cargo bay door to adverse atmosphere and you either need to go almost to the cockpit to get to the drive room, or depressurize/contaminate the living space to get there, even if the drive room is also pressurized!)

If the drive room has an adverse atmosphere, airlock access from the living quarters is available through the attic crawlspace.

I can see giving up the outer (aft) side iris valves, perhaps.

Agreed, but I'm keeping it original for now. Will probably do a "done right" version as well as this "what they probably meant before it all went off the rails" version.

Hmmm ... the dimensions seem to be a little ... on the small side ...

It's vol = base × length / 3, but the base is area = width × height / 2 since it's made of triangles, so the total volume is vol = width × height × length / 6.

At 26 by 18 by 4.5 m a Suleiman would be 26 × 18 × 4.5 / 6 = 351 m³ ≈ 25 Dt.

Most of the volume of the Suleiman is in the aft...

Which is why these deck plans are so misleading. That "massive" bridge space allocation up front.... isn't. It just looks like it.

Sorry to be late to the party, but I would make the computer accessible from the upper maintenance crawlway (attic), and switch main airlock (20) and fresher (8a). You would free up a lot of space behind the cockpit for a fresher, workspace, or something, and put some security distance between the main entrance and the cockpit.

Perhaps an undisturbed sensor cubby instead of the computer room?

Quite, the original plans had 10 sq (15 m) in front of the staterooms, that's just 15 × ~10 × 3 m = 75 m³ ≈ 5 Dt, including the cockpit.

The geometric centre of mass of the Suleiman is around the bulkhead aft of the common area, i.e. behind the landing gear wells (10)...

 

[mike wightman]

The "bridge space " allocation includes:
the cockpit
the avionics crawlspace and surrounding machinery
the mission bay (location 13)
the upper gallery which contains storage, sensor equipment access etc.

Among other things,, the forward airlock is an echo of the Lower Cargo Hold from the original. They wanted an entry point there, so there's an entry point there.

Yeah, it's a bit close to the cockpit.

There's not enough interior clearance in the attic to access the computer room from above.

Yes. Which doesn't help counter the illusion...

The maintenance hatch to avionics is hard to see.
Otherwise, Nice.

That's the one between areas 1 and 2, correct?

That'd be the center of volume, right?

Wait, what? This thing literally has 15% of the mandatory bridge space as optional?!
