Let's say I wanted to make a fairly realistic spacecraft for Orbiter, and I wanted to know how big my various tanks needed to be. For example, hydrazine for the RCS, some kind of fuel for the main engines (LOX?), and something for my crew to breathe so they don't die.
How would I figure that out?
For example, I took a look at the Dragonfly model and found that 3DS Max calculates the volume of those two pill-shaped vertical tanks on the back as about 15.6 million cubic centimeters. Using the FuelTransferMFD by computerex, I found that there's about 10 grams of fuel in the thing. From the information I've found about hydrazine, 10 grams should probably fit in your hand. Not that you'd want to hold that stuff.
So from my limited understanding, something is not matching up. If someone could help me figure this out, as well as the volumes/masses of the other consumables I mentioned, I'd appreciate it.
