The ship would eventually run out of deuterium (and this happened in Voyager at least one time), because not all of it can be reused.
Maybe some of it actually does burn off, rather than being unusable. Or maybe it is unusable, and it's just blown out.

I agree on the 602 metres, but it's interesting that with option 3 we would roughly be at the "canon" length.
Thank you for noticing that, as I forgot to point it out; it is rather interesting isn't it? I think 8 feet is a bit too short for her deck heights, though.

TNG TM says that under most operating circumstances the M:AM ratio in a GCS is 25:1 and that it gets up to 1:1 as it approaches higher warp factors.

What if the thing that makes post-Excelsior designs special is that they're able to go with a pure 1:1 M/AM ratio rather than having to have reactant deuterium to be used in a way that can be energized. That is to say, things like the swirlie chambers probably are some sort of anti-matter spiked fusion plant rather than a pure m:am 1:1 reaction. Hence you'd need the stuff to be reacting at the whole thing of the chamber, rather than in a single reaction chamber.
That's freakin' brilliant... and the supercharger on Excelsior would fit in nicely as a sort of prototypical compromise on the way to inventing the "supercollider" style core.

Oh and by the way, regarding your idea of the swirl chambers, this would also fit the reactors before TMP well I think. Look at the reactor of the NX class, it has the swirling effect too, and maybe TOS warp cores could be similar. The TMP version would then be a kind of evolution of this, a reactor array.

EDIT: The intermix chamber being an "anti-matter spiked fusion plant" could also be supported by the connection between intermix chamber and the impulse engines.
Great points!

I have worked out a bit more math regarding the other starship classes, using the pixel/feet method.

(1) Constitution TOS

(For only this one, I used a differently scaled exported file which is why the pixel dimensions are a bit different, so there's a tiny margin of error compared to the others.)

Option A, Saucer Decks: @ 10 ft, Engineering Decks @ 12 ft

10 ft/13 px = .77

1717 * .77 = 1322.09 feet = 402.97 meters

Option B, Saucer Decks @ 8 ft, Engineering Decks @ 10 ft

8ft/13 px = .615ft/px

1717 *.615 = 1055.955 ft = 321.86 meters

Option C, All Decks Uniform Height @ 10 ft
(For this option, saucer deck heights would be increased to match the scale on the engineering hull.)

All Decks @ 10ft

10 ft/16 px = .625

1717 px * .625 = 1073.125 ft = 327.1 meters

(2) Constitution refit


Option A, Saucer Decks: @ 10 ft, Engineering Decks @ 12 ft

10 ft /27 px = .37 ft/px

3619 px * .37 = 1339.03 ft = 408 meters

Option B, Saucer Decks @ 8 ft, Engineering Decks @ 10 ft

8ft/27 px = .296 ft/px

3619 px *.296 = 1072.3 ft = 326.84 meters

Option C, All Decks Uniform Height @ 10 ft
(For this option, saucer deck heights would be increased to match the scale on the engineering hull.)

All Decks @ 10ft

10 ft/32 px = .3125

3619 px * .3125= 1130.94 ft = 344.7 meters

(3) Miranda

Option A, All Decks @ 10 ft

10 ft/28 px = .357 ft/px

2813 * .357 = 1004.241 ft = 306.1 meters

Option B, All Decks @ 8 ft

8 ft/28 px = .2857 ft/px

2813 * .2857 = 803.7 ft = 244.97 meters

(4) Constellation


Option A, All Decks @ 10 ft


10 ft/13 px = .77 ft/px

1568 px * .77 = 1207.36 ft = 368 meters

Option B, All Decks @ 8 ft

8 ft/13 px = .615 ft/px

1568 px * .615 = 964.92 ft = 294.1 meters

(5) Oberth

Option A, All Decks @ 8 ft


8 ft/16 px = .5 ft/px

1263 px * .5 = 631.5 ft = 192.48 meters

Option B, All Decks @ 10 ft

10 ft/16 px = .625 ft/px

1263 px * .625 = 789.375 ft = 240.6 metersGenerally, I prefer option A for each, including the 8 ft decks on the Oberth. Here's the pretty picture to go with it. (Careful, it's huge.)



In this scale analysis, I've included the scaled dorsal views of the Galaxy and Excelsior to solidify my opinon that even at 602 meters long, Excelsior is still comfortably smaller than the Galaxy, and leaves Galaxy her top dog status quite nicely.
