220509 ISDP メモ
- atmosphere storage
- how much it covers? LEO? GEO?
- where it stands by?
- network / no blackout time
- pressurized section (habitable section)
- sure to have air circulation system
- expendable system (not too much CO2)
e.g.) oxygen candle: sort of like a stick. burns and hold close to their face -> use to breathe
- heat shield capsule
- detachable section
enough analysis
comparing with other capsules
ADCS: trade off b/w how mass efficient they are/ how power full they are
C&DH: human control computer
TT&C: how do you contact with earth
EPS: how much power does it need, solar panels/ battery? how to make it long-term
Bus/ Structure: not very detailed look at similarity with other similar missions, basically a capsule
Thermal Control: life-support system might need more technically complex system: more power, more weight
start thinking about right now
- propulsion
- electrical power: look at Dragon or other similar Soyuz (simple, reliable)
- payload (how many people?, how big it needs to be?)
- trajectory (service area)
basic idea about each system
different options for each category, then choose the best option.
