Artificial gravity

Does anyone know how Traveller handles the problem of artificial gravity with it's ships? I don't seem to recall any mention of rotating hulls, so what do they use?

Grav plates on the floor. Artificial gravity plates that simulate a 1-G environment.

Think of the tech used to make tanks and speeders float used to keep people from floating off the floor instead.
 
Accorxding to the old computer game "X-Com" the grav plates are made of a material that we have yet to discover named elerium-15, some sort of super-conductor I assume. This stuff helps the crew overcome the lack of gravity AND inertia, so they don't go "splat" on the rear bulkhead when the ship moves.

canon says grav-plates AND "inertial compensation" as well, are related subsystems. One Small Step also includes hamster cages, spin grav, and other TL 8-9 pregravitic stuff for MT. T4 FF&S2 included some of this.

TNE's FF&S has different nummbers, but includes the same basic tech. And, IIRC, hamster cages, too.

The CT Lab Ship has always had BOTH grav plates (for IC and under-thrust comfort) and spin "grav" for gravitics sensitive research.

FF7S limited compensated G's of IC by TL. CT/MT didn't specifically.
 
Hello.
I think i said this somewhere else but hear goes again.
I would assume that the grav plates would be in the floor and the ceiling, The plates can either attract or repell.
This gives you normal weight at any excel up to 6g's, The ceiling can switch from repel to attract and so can the floor.
Each plate can be independantly tasked so if the ship is dodging the plates to either side of someone who is moving can be used to steady them by attracting or repelling them under control of the computer.
NASTY thought you could place plates in the walls and it would be a nasty intruder capture system, the floor and ceiling plates go to 3g (hold the object in place with 6g, and the walls go to 3g repell (pressor beams 6g's).
So what do you lot think.
Bye.
 
GT STARSHIPS explicitly says (p.7) that while ships only have grav plates in the decking, it is still possible to play "Grav Pong" (as it is said to be called by the Imperial Marines) with intruders by bouncing them off the floor, ceiling and even the walls through manipulation of the grav plates.

No offense, but Citing GT isn't quite acceptable to many of us diehards: the rules edition as a whole is (by contract) not authoritative, nor is it the OTU. And it diverges in more ways than just the lack of the rebellion, the later virus, the abundance of IM"s generated under other editions who can't wear battle dress....

GT Ship designs are based upon only 2 "fundamentally traveller" assumptions Jump drive size, and range of drive sizes avvailable. Everything else is GURPS Vehicles derived.

Rules-Canon never specified floor only. In GT, yes, that's true. But CT never discussed it in detail, MT did so only in a third party product (but the core for MT does include how much the AG and IC cost and weigh. And, BTW, in MT, they are in fact, NOT the same systems. AG takes far more power (0.05MW/KL affected vs 0.02MW/KL affected) than IC. And costs twice as much, too!

TNE used the MT figures, as I recall... can't find my FF&S. T4 and F&S22 used the same figures for AG and IC as TNE. TNE did set a TL based limit on IC compensated G's...
 
You can have all the gravity you want if you don't have inertial compensators Gravity plates won't help much. I found it interesting that, aside from the Kinunir, most of the combat ships the floors were perpendicular to the Maneuver Drives. (The AHL, PF Sloan and Mercenary Cruiser.) Meaning if the IC failed you would have a limited distance that you could fall. In the CT Scout ship under full acceleration if you were at the Bridge Door when the IC failed and the ship was at full acceleration then you would fall the equivalent of around 45 meters. (Or roughly 15 stories.) OUCH!!! You better grab the first door frame.


On a Mercenary Cruiser the farthest you could fall, assuming Gravity failed first, is equivalent to 9 meters. Still going to hurt but not nearly as bad. Put a couple of toggle switchs on the Bridge with a Red cover to turn them off?
 
Hello.
If your doing anything better than 1G your not going to be very well after hitting the back wall regardless of how far you fall, even falling over at 2G is going to hurt probably even break bones, how would you like to climb some ladders at 2G or reload that missile tube under 6G's random maneuvering, just breathing would be fun.
Bye.
 
Hi !

Space travel and combat without IC/AG really adds some spice

Even with main thrust-perpendicular decks additional acceleration - "stress" is provided by turns of the ships body. Especially on larger fighting ships....

Guess the best place during heavy maneuvering is the acceleration couch anyway.

Besides, how do you think IC is installed in a ship ?
I always thought of a add-on feature of the standard gravity plates.

Regards,

Mert
 
If you are standing on the deck and the deck is perpendicular to the line of thrust then 2G probably wouldn't hurt that bad if you fell over. 3 probably wouldn't break anything unless you landed wrong or hit something. (Though in both those cases walking would be a pain.) Above 3G would probably hurt if you fell over. Remember you haven't had that much time to fall if you are already on the ground so even at 6-g merely falling over is unlikely to be fatal. F=ma 1g=9.8m/s/s You will hit the floor in less than a second. Moving around at those gravities is a bear but if you stay on the floor you should be in fairly good shape.

I get the impression that IC is essentially an extension of the main Grav system that causes everything "inside" to be accelerated equally (thus no inertial effects).

AG is just that: a separate system to produce low intensity grav fields for convenience and safety. Otherwise AG would be just as expensive and bulky as a 1G drive for the same tonnage as the treated crew space - obviously not true.
