Notes on Atmosphere for a Starship

Notes from the Enzmann Archives on Starships ca. 1980s

1) Note regarding air mass and the absurdity of large doughnut stations. Let’s say its five miles in circumference and a quarter-mile wide so the area = (580) 5 (1/4) (5280) = (5/4) 27,878,900 feet2. Pressure 60-70 million tons outward. Steel walls of 20 – 30 feet in thickness?

2) In a very large (long) ship or hollow asteroid at 1/10G over 80 miles, the air at the bow is like that at 15,000 ft; stop acceleration pogo air hits the bow with the force of 9 billion to 60 billion tons. Worse than any hydrogen bomb.

3) Airlocks: sewage and water limited to ¼ of habitat height; ventilation in four levels, access doors in four levels all with separate piping systems.

4) Safety locks and pogo control: three-door ports

Plus slosh torque control and three layers of triple locks

5) auxiliary vehicle air conservation: a: glove docks for ANPs b: refuelers c: fleet shuttles d: gangplanks gangway knees

6) Spacesuit use: via pod locks, use waffle-pads with pod locks

7) Air conservation: strip (foil strips) welded oven all seams in deep space

8) Air storage: as frozen gases, as chlorate candles

9) Fail safe on power loss all doors lock: floors – bulkheads need power-on to be opened, leak warning between hulls, differential pressure monitoring

10) Recycling air: 60 ft2 of green leaves can turn one human’s CO2 into O2; plants remove dust from the air. Note: plants need chemical/physical recycling by machinery

11) Quality of air: heat/cold, humidity, sound-proofing, circulation with draft control

12) Pressure: like Denver, even at the climax of Colorado 12,000 ft to 15,000 ft, 5000 ft.
