This is also a repost, because - like the Free Trader design - the demon at
engrg didn't answer.
How to create Damage Tables for TNE.
When I finished the Technical Booklet (TB) of Brilliant Lances I found, that
a description of the creation of Damage Tables for the new created Spaceships
is missing. In the Design Evaluation chapter on page 17, I found only vague
hints on how to create them. Here is my solution, to create these tables.
The 200 tons Beowulf class Free Trader is used as an example.
1. Calculate the volume of the ship's components as suggested in step 3 of the
Design Evaluation.
Beowulf: Electronics: 47.312 kl
Hold: 1947.288 kl
Quaters: 518.400 kl
Engineering: 203.000 kl
Weapon Mounts: 84.000 kl
total: 2800.000 kl Ship Volume
2. Calculate the percentage parts of these components compared to the ships
displacement:
to calculate: Beowulf
---------------------------------- -------------------------
ElecPart = Electronics/Ship Volume ElecPart = 47.312/2800 = 0.01690
HoldPart = Hold/Ship Volume HoldPart = 1947.288/2800 = 0.69546
QtrsPart = Quaters/Ship Volume QtrsPart = 518.400/2800 = 0.18351
EngPart = Engineering/Ship Volume EngPart = 203.000/2800 = 0.07250
WeapPart = Weapon Mounts/Ship Volume WeapPart = 84.000/2800 = 0.03000
3. The whole ship has 400 (20x20) damage locations. To get the damage
locations of the single parts, multiply the calculated "Part"-Values
by 400. The result is the number of damage locations each component
has.
to calculate: Beowulf in %
------------------------ -----------------------------
Elecdam = 400*ElecPart Elecdam = 400 * 0.01690 = 7 1.75
Holddam = 400*HoldPart Holddam = 400 * 0.69546 = 278 69.50
QtrsDam = 400*QtrsPart QtrsDam = 400 * 0.18351 = 73 18.25
EngDam = 400*EngPart EngDam = 400 * 0.07250 = 30 7.50
WeapDam = 400*WeapPart WeapDam = 400 * 0.03000 = 12 3.00
4. You have now calculated the damage locations for the internal Explosion
damage table of the ship. Now these locations must be placed. To do this,
imagine the exterior design of the ship, as you would like to see it.
That's easy for the Beowulf, because there are enough pictures and even
deck plans around, to do this.
Some hints:
To find the hit location of the ship, you first role a D20. This roll
select the hull part using the "Hull Surface Loaction" picture (page 17
Brilliant Lances Rules of Play (RoP), or page 319 in TNE).
To place the damage location think of the globe sections as the directions
from where incoming weapons reach the hull. Then remember your intended
interior design of the ship. Think of the parts of the interior which can
be damaged, if a weapon hit from one of the sectors of the globe. Keeping
this in mind, you choose these of the five categories, which can be touched
by a hit from this location. You need at least a rough idea on how the ship
shall look like.
Every Component with more than 20 hit locations could count as one line
in the damage location table. That's true for the Hold, the Quarters and
the Engine Components in this case. The other components damage locations
have to be placed for a second D20 role.
BTW: Only a sphere shaped ship can apply this damage locations without
bothering shadows for the incoming fire. Think of the fire arcs of the
different fire locations. If a ship fires in this arc, it should not be
able to damage the weapon installations. If you like to use details, it
would be an interesting work, to place the damage location with more
details :).
Result of this steps is the damage location table for internal explosions.
And the surface damage? Well, you should use the same method:
1. Caculate the antenna area, cargo hatch surface, launch port surface and
Air Lock surface. Then find the part of the ship's surface they take.
You can calculate the ship's surface by using the MV-value of the Hull
Size Table (p.2 TB) multiplied by 100.
to calculate: Beowulf:
----------------------------------------- ---------------------------
AntPart = antenna area/ship surface area AntPart = 15.4/900 = 0.0171
CHPart = Cargo hatch area/ship surface CHPart = 40.0/900 = 0.0444
LPPart = Launch Port area/ship surface LPPart = 16.0/900 = 0.0178
ALPart = Air Lock area/ship surface area ALPart = 4.0/900 = 0.0044
EMMPart = EMMRad area/ship surface area not available
I've calculated the Air Lock Surface area as 2 square meters for the
exterior door. I havn't found any hints on the true surface area.
2. Use the calculated values to find the surface damage locations.
to calculate: Beowulf:
AntDam = 400 * AntPart AntDam = 400 * 0.0171 = 7
CHDam = 400 * CHPart CHDam = 400 * 0.0444 = 18
LPDam = 400 * LPPart LPDam = 400 * 0.0178 = 7
ALDam = 400 * ALPart ALDam = 400 * 0.0044 = 2
EMMDam = 400 * EMMPart
Step 4 of the Design Evaluation chapter says, that external grapples
are part of the surface fixtures. If you check through the tables, no
ship uses this. Every ship which has an external grapple locates its
Small Craft there.
3. Locate these damage locations on the hull. Use the same method
I hope the ideas mentioned above are of some help. It took me 3 hours to
figure out how to calculate and place the damage locations on the Beowulf
class Free Trader. It took much less time on the Marva class Far Trader.
I hope with some routine, I can create this tables a bit faster.
All in all a ship design for BL takes about 3 hours for small ships. I don't
know how long it will take on large ships. I will soon try :).
With calculated damage tables....errr...well...
