Spherical Volume: 1000 Meter Diameter

Ok, feel free to correct the math-dummy here.

Sphere: 1000 Meter Diameter.

4/3 * PI * 500 ^ 3 = 523,598,776 cu m (according to MS Excel 2000).

Now here's the biggie . . .

523,598,776 / 13.5 = 38,785,094 dTons.

or . . .

523,598,776 / 14 = 37,399,913 dTons.


Did I calculate all that correctly?
 
I checked and the results are correct.

Using the 37,399,913 dton result I figured how thick a TLF armor factor of 1 (external only), for such a ship would be: 3.356m (11 feet)

A 'standard' hull thickness of 0.152m (6") would have a tonnage (using CT 14m^3/dton) of 33,649.8 dtons, almost half of a AHL class cruiser.

IMPRESSIVE!
 
Randy,

Thank you.


33K dtons for a hull? I'm pretty sure the Imperial Palace has armor on top of that. :D Just think of what that will mass per factor!

I wonder how many Type-T Spinal Mounts I can stick in this Great Ol' Biggest Happy Fun Ball o' dem All?

Oh! Given the volume, I wonder how much the Aquarium masses in dead-weight tons of water?

According to High Guard, MT, and T20 - one ;)

Well, water has a density of one ton per cubic metre...

In the unlikely event that Cleon City ever has a water utility breakdown, all they have to do is run a hose up to the Imperial Palace and it becomes the most expensive floating water tower in history.

My rule is 1 spinal mount per million dtons

Start the topic.


I won't be able to respond until late tomorrow evening, at the earliest, though. I'm going to bed in a short while, and won't be back at the my PC for a while.

Check the numbers again! You say 35K dton, but the afore mentioned hull is 37m+ dton. Which did you intend to use?
 
I think he meant 35,000. Designing at 35,000,000 would take too long for a "little" contest.

I've had some problems today, and tomorrow is right out. But this is not out of my thoughts. I haven't seen the right topic started up yet, though.
 
I know Andy is going to kick himself when he wakes up. It's nothing I haven't done myself, simple errors require complex minds ;)

The 520 million the convertor threw out was the cubic measure of volume. In this case 500 meter radius so 520 million cubic meters as Chris calculated above. You just forgot to divide by your choice of cubic meters per displacement ton to arrive at the smaller 38ish million displacement tons.

Edited to correct the decimal place, didn't check Andy on that. Chris caught it but still seems to think below it's dtons?

A factor of 15 armor (16% of total ship mass) will be 5,983,986 dtons. If all of the armor is considered to be the hull (ie no internal bracing) then it would be 28.23m thick. That would be 92 feet, 7 1/8 inches of solid metal armor.
 
Yet one more point in favor of my heretical leanings that "tons" in starship design should be and have always been meant as mass tons and not displacement tons.
 
Hi !

Randy, is there perhaps a bug somewhere ?

Using Ships for Windows it spits out around 2,8 million tons of additional mass for an armor value 15/F.
This results in an additional hull layer of a few cm's (18 cm using normal steel, quite less using superdense stuff).

The number 5,983,986... is this really mass in tons or displacement in dTons ?
Which ruleset did You use ?
 
I used his 37,399,913 tonnage as a base figure. In CT/HG (14m^3/dton) a factor 15 armor uses 16% of the displacement tonnage. I subtracted the armor tonnage of 5,983,986 dtons from the original then recomputed for the radius of the resulting 31,415,926.9 dtons of ship. That would be 471.77m subtracted from 500m leaves 28.23m for the armor hull.
 
Ah, thats a really funny HG thing


In MT they turned towards just specifying the mass of additional armor. So using some reasonable densities and calculating back to volume keeps the hull thickness in limits.

Guess assuming enhancement of internal structure might be a solution, too.
 
Or to add heresey on top of heresey HG armor might be some kind of early reactive force shield since it is tied to volume and not area.

The up-side, ships can maintain their canon look with lots of holes (port holes, hatches and such) while still being protected. As a bonus it also allows ships to be upgraded with more protection as long as sufficient volume/mass is available internally, like in a cargo hold.

The down-side is of course that it has no power requirement so how does it work.

Short of that yes, the best way to go is figure that most of the armor allotment on bigger ships is internal bracing and compartmentalization.
 
Dan makes a worthwhile point here, High Guard armour was never described - bonded superdense etc. were a Striker invention retconned into HG by implication in the Striker rules, and then canonised by MT ;)

High Guard armour could indeed be some sort of cold plasma designed to absorb laser beams etc.

Here's the link I usually use at this time ;)
