Chapter
18 Crew
(&Payload) Accommodations
Learning Objectives
1. Identify Design Requirements driven by Crew & Payload Accommodations
2. Describe various categories and solutions typically used to meet these needs
Emphasis
Describe Systems Engineering considerations
Summarize Interdisciplinary Requirements / Considerations
Address environmental adaptation issues (microgravity, isolation, )
Human Support in Space
Protect from hazardous environment
Pressure vessel / structure, spacesuit
Provide life sustaining needs
ECLSS, Thermal, Power, EVA
Maintain long-term health
Countermeasures (physiological & psychological)
Provide comfort and convenience
Crew Accommodations
General limitations
associated with living in a spacecraft
1. Low levels of environmental comfort
cramped quarters
poor ventilation
temperature/humidity imbalances
high ambient noise
odors
shared sleeping quarters
etc.
2. Inconvenience
rationed showers
lessened hygiene
limited wardrobe changes
unappetizing meals
limited recreational activities
regimented activities
etc.
3. Limited personal control
restricted news access
limited family/friends contact
heavy work schedules
rules and regulations
etc.
Crew Accommodations
Hardware, software, procedures
Support Equipment: hygiene, sleep, rec, cooking
Clothing
Not always clearly indicated in systems requirements or mass, power and volume allocations
