Jump/Grav relationship

[Fersboo]

N00b question I'm sure. I'm working off of the CT cd-rom and still need to read more, but I am interested in what relationship the jump/manuever drive has with the grav plates. That is, at what level of performance would require that grav technology was necessary.

Not certain, but the fluff states that Jump was discovered by accident by the Solomani during experiments being preformed in the asteriod belt. THey were doing some reseach to improve the power or efficiency of thruster drives at the time.

Grav plates are assumed to compensate for the thrust applied by the M Drive, whatever that thrust is.
Jump drives don't create acceleration so they have no relation to grav plates.

Hope that helps.

Sort of. I guess I should get the terminology correct first. Is there an amount of Gs that exceed the operation of craft without grav plates? I want to create an ATU that doesn't introduce Grav plates/inertial dampers (how I read what the Kzinti had in Niven's Known Space) until humaniti meets an outside alien race. Does that make better sense of what I'm fishing for?

IYTU you can do what you want. Thrust plates and CG, hence inertial dampers all are interrelated technologies. Nothing stopping you from doing something different thou....

Somewhere it says that internal compensation is the limiting factor for G's. If, in your TU you want to either go beyond that, or go before/without, then the floor is open. Having decks parallel to the axis of thrust then becomes critical, and the ability to strap everyone down a la Apollo.

I always favored the idea of military ships, especially fighters and gunboats, being able to exceed internal compensation, with everyone strapped into proper acceleration couches, for a couple or three g's extra here and there, but I never worked it into any of my work.

Traveller uses whole numbers of Gs. Since 1G is more than enough to do serious harm (as evidenced by any fall on Earth) there is no minimum safe G force in Traveller.

If you want to have ships with no grav plates you will need to fit acceleration couches for every occupant, to be used whenever thrust is applied.

You will have a delay as people prepare for thrust, but this shouldn't be significant with 10 or 20 minute turns.

You may decide that every stateroom has acceleration couches built in, or you may choose to add them seperately.

Nobody can force you to stick to the rules, your universe is your own. Play it how you want.

Have fun.

PS. You may benefit from designing your ships as 'tail sitters' with the 'floor' tailward so that application of thrust acts like gravity. You'll still need couches though, just in case something goes wrong and to protect occupants in case of impact forces from combat hits and from contact with an atmosphere.

Without grav plates, every jolt will cause problems for persons without couches.

Hope that helps.

Not sure if you'll find this interesting...

Thanks. I guess I should have considered that 1G is dangerous. o:

As to it's your TU thing, I still want to follow some rule structure and not be all space opera/hand-wavium about things.

I like the manual.

Also, even if you use the "thrust as gravity" idea, you are then stuck with 1G, or something pretty close, and you are zero-g without thrust, to include "flipping" in the middle of a journey.

That is why I would only consider military vessels (essentially small craft, at that) for any uncompensated G's. Then again, these vessels would probably use such acceleration under exceptional circumstances.

I always liked the idea of no compensators, and stacked floorlike decks, and constant 1g, so the crew can walk about, with a central lift tube / device, sealable by a quick-closing valve/airlock.

When in combat, or maneuvers other than 1 or 2% off course, the crew straps down into acceleration couches for maneuvering.
