AQUIFER Concept

Wing Demonstrator

Rim-Driven Motor (RDM/RDF)

• Fire / Explosion Hazards

• Recharging Time

• Radiated EMI

• Coupled Power & Energy

• Range Limitations

• Noise Concerns

Electric Propulsion Barriers

• Charging time equal to fuel pumping

• Co-locating power & energy, no long cables

• Need more power – more stack area

• Need more range – more fuel

• No hub or blade-tip interference noise

• Aqueous fuel

AQUIFER Technology Benefits

Nano-electro fuel (NEF)

Future Considerations

• NEF Generation 2 (GEN 2) Development

• Maintain non-explosivity / non-flammability

of GEN 1

• 1-year Target: 75 Wh/kg

• 3-year Target: 500+ Wh/kg

• Air-bearing development

• Improved motor acoustics

• Improved motor thrust• Minimal complexity increase
