  2. Mission Statement • Implement advanced technologies to design a future large commercial airliner (200 passenger minimum) that simultaneously addresses all of the N+2 goals for noise, emissions and fuel burn as set forth by NASA. • These NASA goals include: • Reduce noise by 42 dB below stage 4 certification noise measurements at takeoff, sideline, and approach • Reduce landing and takeoff NOx by 75% below CAEP6 • Reduce fuel burn by 50% relative to a “large twin-aisle reference” • Reduce field length by 50% relative to a “large twin-aisle reference” • Use market driven parameters to design a realistic and desirable aircraft.

  3. Customers

  4. Regional Market • Similarities in market predictions

  5. Regional Market • After 3 major domestic markets, many major international routes with high demands Airbus Market Outlook

  6. Competitors

  7. Competitors • B787-8 • Replace B767-200ER, B767-300ER and possibly B757-200 (on shorter routes) * indicating aircraft will need replacement

  8. Competitors • B787-8 will be have no competition for small twin aisle aircraft carrying 200-250 passengers • Compete against B787-8, assuming the proliferation of point to point model as opposed to hub and spoke distribution • Smaller, long range, efficient aircraft offers economical option to open up markets into low volume city pairs.

  20. Sizing Capabilities

  21. Current Sizing Tools • Empty Weight Prediction • for Jet Transports • This equation is from Raymer Table 3.1 • Fuel Weight Prediction • Requires fuel burn prediction and drag prediction

  22. Current Sizing Tools • Drag Prediction • Use similar existing aircraft AR to estimate (L/D)cruise • for subsonic aircraft • This equation is from Nicolai Figure 5.3

  23. Current Sizing Tools • Fuel Weight Prediction • Use Breguet range equation and endurance equation • Total Fuel • Add 1% for trapped fuel

  24. Sizing Calibration • Baseline Aircraft • Boeing 767-200ER http://boeing.mediaroom.com/index.php?s=13&cat=30&item=1126

  28. Predictions Using Sizing Tool • Noncalibrated Weights • Calibrated Weights

  29. Summary & Next Steps

  30. Next Steps • Refine sizing code • Powerplants • Thrust-to-weight improvements • Aerodynamic designs • Airfoil design / Finite wing design • Fuselage • CAD Model of aircraft • Estimation of new technologies on specifications
