TL-13 Laser Design Problem

A

ArcaneFlash

SOC-10
I was designing several FF&S spreadsheets. One was for designing CLC Cartridge Lasers. When designing a Laser pistol, i first set up a TL Chart. I first tried to set up using standard cartridges. I compared them to the standart TL13 pistol in the book.

I got some bizarre results:
TL-13 2cm Pistol 0.01 Pulse, DV: 3, Pen 1, R: 80m, PerDamDice: 63(?)

Why 63 Dam. Dice? I used PDD = SQRT(I)*50

Any Ideas?

PS on Missiles: 0.75 M^3, 800kg, 50kg HE warhead, DV: 45, Pen 16, 14 G-Turns. Does this sound right?

DV = 2.5 times Square root of intensity Damage dice = 50 times square root of intensity. that's a 20:1 ratio, so 3 DV =63 damage dice sounds exactly right.

If you shoot something that has an AV of 3 the armour stops 3 of the DV of the shot or 60 damage dice, only leaving 3 damage dice if any.
 
I'll look at my tables again, but yes I had penetration.

BtW: I tried to reverse engineer the Space Missile, Mine was like 16-G opposed to 12-G (TL 9 or 10)

Second, Which Ship design rules do you guys prefer? CT, MT or FFS?

FF&S, once you get a spreadsheet set up, (or use one of the ones published on this site), designing a ship only takes a few minutes, and you can specify nearly anything. BTW there is very little differance in the formulas between TNE's FF&S and T4's FF&S, TNE has better explainations, T4 has better organization.
 
T4's use of KN's kind of confused me. What do you use instead of EAPlaC? I created a nice HE version of a Photon torpedo in FFS 1. But I noticed the main problem of getting CT standard missile size was the SRFed engine size-inefficiency. So, I'm considering dropping it and seeing what I get.

Also, How would I determine contact damage for a nuclear Missile?

I'm trying to work out a version of SFB ships for Traveller and noticed FFS 1 seemed to fit the bill. So, I'm planning on 3 sizes of missiles. Not sure how to do Disrupters. But I'm limiting energy weapons to 1 LS. I want 10,000 km/hex. I'm staying sublight combat. Any suggestions on timescale?
 
For TL 13 through 16 inclusive I use HEPLAR attached to a Fusion power plant and a fuel tank. The HEPLAR is pretty much an Ion drive.

I've posted elsewhere on this board the various therotical maximum performance of this combination. Suffice to say the TL 16 one gets 81 g's.

If you're running star fleet battles in Traveller don't limit yourself on the tech, you need tractor beams and antimater power, so that puts you in the TL=17 at a minimum.

Ok SFB uses an impulse system to break up the combat round such that no ship can ever move two hexes in one segment. So let's establish a impulse speed limit of .1c (30,000km/s) so your segments would be 1/3 of a second with a 4 second turn for a 12 segment turn.

A 10,000km hex = 1000 sec turns for 1 hex=1 G-Turn vector change.
1000 sec is 16.6 minutes. If, of course, you're using Traveller standard 10m/s/s G's and rating Impulse drives in G's.


If, instead, you use 10PSL increments constant speed, so as to match Trek canon closer, a 6 sec turn would mean crossing 1,800,000km per turn at 1PSL, so you'd be looking at needing to cross 18 per turn...
In a 2 second turn, you're crossing 600,000km/turn, for 10PSL=6 hexes a turn.

Personally, I'd use a hybrid model. Each rating is 10 PSL maximum speed, and an acceleration/deceleration of 1PSL; sidelining an acceleration of 1/3 current velocity produces a 30° turn, and use 3.3 second turns.

I've never used FFS before, but are you sure there isn't a rule requiring lasers of a certain size to have a penetration of nil? Any penetration on a laser pistol is surprising, but 1? That's awesome.

Page 129 in the second printing of FF&S states that you need an intensity of 0.390625 Mj per cm2 to get a penetration rating, anything less - and that includes things like the Squad Support Laser - and the penetration rating is nil.
 
I made a series of basic laser pistol CLC stats from TL 11-16.
The cartridge size is a uniform 10mmx30mm.
Intensities:
TL 11-12, 1 Mj/kg, DV: 2, DE 0.005, I: 0.781, R: 0.08km, IPR: 1, PerDamDice: 44
TL 13-15, 2 Mj/kg, DV: 3, DE 0.01, I: 1.563, R: 0.08km, IPR: 1, PDD: 63
TL 16...., 3 Mj/kg, DV: 4, DE 0.014, I: 2.188, R: 0.08km, IPR 1, PDD: 74

Cartridge size: 18mm x 32mm.
TL 11-12, DV: 4, DE: 0.016, I: 1.975, R: 0.09km, IPR: 1, PDD: 70
TL 13...., DV: 5, DE: 0.032, I: 3.951, R: 0.09 km, IPR: 2, PDD: 99

Cartridge size: 20mm x 32mm.
TL 14-15, DV: 6, DE: 0.040, I: 4.938, R: 0.09 km, IPR: 2, PDD: 111
TL 16....., DV: 7, DE: 0.061, I: 7.531, R: 0.09 km, IPR: 2, PDD: 137
