Ship Design Philosophy

Spaceships: Life Support and Camping Out

Q. Vehicles have a slightly different variant of life support.

R. One vehicle space is equivalent to a quarter spacecraft tonne.

S. Long term technological level seven life support is for ninety days, one space sufficient for five people, at fifty kilostarbux, two hundred fifty starbux per month.

T. Short term technological level four life support is for four days, one space sufficient for twenty people, at ten kilostarbux, at fifty starbux per month, in theory, six and two thirds starbux per four days.

U. Consumption costs is covered by monthly maintenance cost, half a percent per month.

V. One issue is being able to separate these functions from their originating design schemes.

W. The easiest way is transplanting the entire mechanism to the spacecraft.

X. This covers issues such as power requirements, and what's required to ensure that the item functions as expected.

Y. You could install the life support unit on a golf cart, that putters around the spacecraft, spreading the good air.

Z. Also the fresher, which can be emptied afterwards.
Spaceships: Life Support and Camping Out

1. Life support could be considered having four aspects, at least for humans.

2. Oxygen supply.

3. Water supply.

4. Climate control

5. Food supply.

6. Arguably, waste removal.

7. It's quite possible, this is all regulated by one or more interstellar, or planetary, authorities.

8. Or, at least, while operating within their exclusive economic zones.

9. Or maybe not.

Spaceships: Life Support and Camping Out

A. Each room or compartment is likely to have a door.

B. It's seems unlikely that you can have a distributed life support system.

C. If you include areas like cargo holds, the oxygen content would be severely diluted.

D. If life support is concentrated in the crew and passenger cabins, every else you'd have people wandering about in rebreathers, if not, oxygen masks.

E. It's possible, if life support is continuously on, long enough, the entire spacecraft will be full of the correct oxygen/nitrogen mix.

F. I'm thinking that you install a life support module on a Roomba, and distributing oxygen while it cleans the floor.

G. A twin set of compressed oxygen tanks, allowing independent breathing in smoke, dust, gas or Exotic atmospheres.

H. Two tanks last six hours.

I. These tanks are not suitable for underwater use, see underwater air tanks (Page 114) instead.

J. A refill of proper atmospheric mixture for any given species costs Cr20.

K. Technological level five - would assume at technological level fourteen, with bonded superdense, you can stuff in more oxygen.
Starwarships: Drop Troopers in Sci-Fi Warfare (Helldivers 2, ODST etc)

With the recent success of #Helldivers2 we've been thinking a lot about Drop Troopers as a sci-fi combat trope.

1. Ortillery.

2. Angle of attack.

3. Low down.

4. Flak.

5. Deceleration.

6. Flight time.

7. Inertial compensation, and airbags.

8. Landing blind.

9. Local mobility.

A. Ascertain local resource exploitation.
Spaceships: Hulls and Bunkerage

1. Instead of storing the ship’s hydrogen fuel in liquid form at extremely low temperatures with a high risk of explosion if a leak occurs into the inhabited spaces of the ship, it is possible to store hydrogen at room temperature using a non-flammable metal hydride matrix.

2. This takes up more space but is safer.

3. Metal hydride storage replaces a ship’s normal fuel tankage but consumes twice as much space and costs MCr0.2 per ton.

4. I would have thought compresses stuff makes it smaller.

5. If we armour the fuel tank bulkheads, or just armour the fuel tanks, how far can we compress the hydrogen?

6. Can we fuel the jump drives, while the hydrogen is under (increased) pressure?

L. Ye, many moons ago, I did the calculations of cost comparisons between default life support and biodomes.

M. In the short and medium term, you might as well just pony up for the default costs.

N. Long term has some inherent risks, like someone shooting out your starship under you.

O. Or, the biodome is infected by black mold.

P. Each human requires half a tonne, half a power point, at one hundred kilostarbux, which means you're paying for that real estate (and operating costs) as well, whereas default life support can be viewed as virtual.

1. Reasonably airtight.

2. Fifty to eighty atmospheres.

3. Carbon dioxide scrubbers run indefinitely, if powered.

4. Space sparks.

5. Sauna.

6. Parachutes.

Q. Speaking of oxygen dilution, you'd think that common areas such as dining areas would have additional life support, to compensate for the anticipated crowds.

R. Galleys with gas stoves and barbeques grills would probably need that as well.

S. Training areas, considering all that extra grunting from exertions.

T. Laboratories have Bunsen burners.

U. And medical bays probably need them in a easily accessible form.

The docking clamp system in Mongoose seems rather unrealistic, but that aside.

The thing about docking clamp/victors is that they have limitless tonnage, from fifty tonnes onwards, at two kilotonnes plus, one reason I decided to redesign anything between one and two kilotonnes, and became convinced that the Confederation Navy wouldn't really bother with anything less than five kilotonnes, especially if they plan to transport it via docking clamps.

At the scale where you likely plan to transport a hundred kilotonne hull(s), and you want to accompany it with about kilotonne extra hulls, buy extra docking clamps for your battle tender.

Otherwise, have a scaled down variant that just handles smaller hulls, that can accompany the primary tender.
I always applied this rule from High Guard

All space stations are capable of externally docking with a number of ships whose total tonnage does not exceed twice their own tonnage. Alternatively, a single ship of any size can dock with a space station. This is achieved through the use of docking arms and clamps, which are assumed to be purchased and installed during the construction of the space station’s hull.
1. One primary difference between a default spaceship, and a default space station, would be mobility.

2. The space station is unlikely to be accelerating, so external docking facilities are unlikely to be under stress.

3. Unless some freeloader trader declines to pay docking fees, and decides to just take off while still hooked up.

4. Regarding capacity, those listed in Traveller could be viewed as guides.

5. If you've seen it in real life, you have to wonder exactly how underway replenishment works in Traveller.
