Current Technology Boeing 787 Dreamliner  $243.6M  242 Passengers  9400 mile range  Cruise: 567 mph  33,528 gallons of fuel

787 Cockpit

Airbus A350  $278M  314 Passengers  Expected Launch in 2013  9300 mile range  Cruise: 561 mph  36,500 gallons of fuel  Video: :13-:50

Needs:  Lighter (Fuel efficient)  Faster Range ~20 years

Box-Wing Jet (Target: 2025)

Box Wing Jet cont.  Lockheed Martin  Increase range, still fit in airport gates  Materials from F-22 & F-35  Loop-wing = 16% incr. lift-to-drag ratio Steeper decents with less power  Two ultrahigh-bypass turbofan engines Another 22% increase  Total = 50% increase in efficiency over average jetliners.

Sugar Volt (Target: 2035)

Sugar Volt cont.  Boeing  Size of a 737  Hybrid Takeoff = jet fuel + batteries Cruise = batteries  Thinner wings + higher lift-to-drag  Wings fold to fit into gates  Hybrid + high-lift wings + open rotor engines = 55% more efficient  Emits 60% less CO2 + 80% less N2O

Supersonic Green Machine (2030)

Green Machine cont.  Lockheed Martin  Redesigned Concorde from 2003  After burners reduce NOx by 75%  Inverted V-shaped tail mitigate sound waves No sonic boom, just dull roar.  Cruises at Mach 1.6

Volta Volare GT4

Volta Volare cont.  Portland-based Volta Volare  Hybrid powertrain 900 lb. Li Polymer with 236 cells  Uses $20 in electricity vs. $80 in fuel 200 mile flight  Only one moving part in engine Less Maintenance  Takeoff, climb, and cruise 300 miles on solely electrical power.  Future: replace fuel with more batteries

Solar Impulse

Solar Impulse cont.  Swiss company  Weighs less than an SUV  165 yards of runway to take off Over a mile for a commercial jet  Completely solar powered  Can fly at night  Cruise: 43 mph  20 day world trip in 2015
