Are there artificial gravity in spaceships? (Terracide)

[Theros]

Is it possible to get? If it is, how big ship need to be to get it?

Well, there aren't any "rubber science" artificial gravity generators like in those SyFy shows; the only way to simulate gravity in space is with spin gravity. Generally speaking, any spacecraft with Size of 15 or greater can be given a rotating hull when it's built. This is a one-time decision; it's extremely difficult to retro-fit a spin-hull onto a spacecraft after it's built. It's either designed to rotate or it's not.

 

Most spin-hulls on Terracide spacecraft won't be spun up to a full G, to reduce stress on the hull. One third of a G is enough for most purposes and it's a good compromise for everyone -- it keeps the "baseline" humans oriented and doesn't fatigue the Aquila types (and other low-G types) nearly as much. Also on smaller craft, higher G-levels require a spin rate over 3rpm, which is disorienting for almost everyone. (Hence the Size 15 requirement.)

 

Also worth noting: most spacecraft without spin hulls have enough fuel to boost at one-third of a G for a couple weeks if needed. It's usually considered a waste of fuel, but if they really want to simulate gravity that way (or if they're just in a hurry!) they can do it.

Ok. I am just getting some cargo + passenger ships to my campaign. I am in need of layouts ( as there happens attacks and so on inside the spaceship, when it is transporting passangers + PCs. I need to check that size thing then.

At this time, I haven't done any official starship deck plans. Which ship class do the PC's have?

 

In the near future I expect to have some floor plans (by a professional artist!) for the Gravity Model independent merchant and possibly the Man of War fleet intruder. Both of those are small ships in the Size 10-12 range.

 

Some general guidelines: Terracide starships use an "engines down" configuration, with the decks stacked vertically above the engines, so they can simulate gravity using engine thrust. (And so that high levels of thrust don't slam everyone into the walls.)

 

In general, spaces tend to be cramped: two hexes per crew member is a good minimum, although most ships will have more than that.

 

Anything that doesn't need life support will not have it: cargo, fuel, docking bays.

 

Areas that need to be secure will be on their own separate decks: flight controls (the bridge), hibernation units, weaponry, engine room.

Ship that I am going to use is in three floors. It is modified Nasa space shuttle from outlook. The lowest floor is cargo bay. Second floor is for passenger seats and the highest floor is floor for sleeping and other areas. Designed maximum trip will be 30 days.

 

Ship is 44 meters long, 16 meters wide and 10 meters in height. Main thrusters are located behind the ship, like all other engines and air systems. Those are located in the lowest floor only.

 

passengers should be seated during the take off and when ship is maneuvering. In other situations they are free to spend time in two floors. Ship will have three security personnel and around 40-50 passengers at max + pilots and other staff personnels.
