General Question DGIV cabin atmosphere?

[EnDSchultz]

Just a random question, wondering if the cabin settings have any impact on the craft within the context of the simulation (IE, high pressure with low oxygen vs low pressure with high oxygen), and if not, what would the purpose for changing the atmospheric conditions inside the orbiter be in reality?

 

[Bloodworth]

The purpose behind changing the cabin atmosphere is the survival of your crew...
The DGIV (as well as the XR series of vehicles) require UMMU to operate and if the crew dies then the vehicle becomes uncontrollable.

 

[EnDSchultz]

Yes, I understand this. I suppose a more accurate way of phrasing my question is: what difference does it make, if any, as long as I keep the atmospheric pressure/oxygen ratio within the "green" band on the DGIV atmosphere graph?

I'm not 100% certain, but AFAIK there is no impact on the operation of the vehicle other than whether or not the crew is alive or not. HOWEVER, there are some situations you may want to change it, if you miscalculated your trip time to Mars and find that the crew will run out of oxygen 47 hours before you reach a base, then you may want to manage the oxygen usage levels early before a serious problem develops and see if you can squeeze the extra time out of the tanks, giving the crew acceptable but lowered O2 levels.

I found the DGIV atmosphere control feature really fun. If one could count how many UMMU's I'm accidentally killed when experimenting with life support control panel. I also like to keep the lowest possible oxygen setting just to keep the crew barely allive.

uh.... why? :lol:

I won't be flying on your shuttle any time soon, Captain! :lol:

Thanks for the responses, guys.

This atmosphere feature is the equivalent of air conditioning in a plane.
But unlike planes, oxygen is consumed in a DGIV.
It does not become an issue, unless you are short on oxygen.

Life support in interplanetary craft would involve more devices, which basically recycle human waste and would produce food. This kind of system would be more appropriate for an Arrow freighter because of the demand of space inside the ship.

One more point:

In reality it's important to make EVAs in low pressure high oxygen conditions to prevent the spacesuits from blowing up like balloons. Remember the issues the russians made in first spacewalk.

So, if you want to make it as real as possible, you will have to lower pressure very slowly while inreasing oxygene over an at least 12 hour period before you can dock out any of your Crewmembers.

Thats what they are doing in real ISS

I would... but i guess i'm not that hardcore. mostly interested in the flight aspect!

Ouch. That IS hardcore.

Please get me right;

I don't want to simulate that every time. Especially because Orbiter doesn't take care of it. It's even not computed in UMMU. And DanSteph forgot of caisson disease when he was coding this wonderful DGIV. But that is the reason for the necessary long decompression time. We have just to remember things like that because of the deadly consequences they would have for our crews in reality.

And if you want to decompress and refill your docking-chamber very frequent on your journey...
Do it with low pressure in your DGIV
