Aircraft Design Class

2. Lavatory, Galley, and Water System
Important to include in preliminary design.
Large investment in weight
Large investment in volume

3. Typical Layouts

4. Galley All food prep is done on the ground Equipment
Coolers
Warmers
Coffee Makers
90 – 100 KVA allocated

7. Water supply .3 gallons per person Pressurized by pneumatic system
Water quality regulated by EPA
Tanks have to be flushed and disinfected

11. Lavatory

12. Lavatories Rule of Thumb: 1 lavatory per 30 passengers
They use very little water (about 0.5 gallons per flush)

13. Lavatory They can use much smaller diameter sewer pipes
They can flush in any direction, including upward. Since a vacuum system does not use gravity to move the water, there is nothing to stop the sewer pipe from going straight up
They can be put anywhere in the aircraft

14. Waste System Self contained
Waste tanks and flushing units mix the waste with chemicals
Vacuum flush from in flight pressure differential (No gravity plumbing)
Must be serviced after every flight.
Drain locations need to be positioned carefully

17. Removing Waste

18. Food for Thought
Doesn't apply for UAVs or HPA
Military Transports?
