Aircraft Galley, Lavatory, and Water Systems Ryan Koubek & Mike Maloy Team 3 September 14, 2006 Aircraft Design Class

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

Typical Layouts

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

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

Lavatories • Rule of Thumb: 1 lavatory per 30 passengers • They use very little water (about 0. 5 gallons per flush)

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

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

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