Mission statement
Mission Statement

To design an environmentally responsible aircraft for the twin aisle commercial transport market with a capacity of 300+ passengers, NASA’s N+2 capabilities, and an entry date of 2020-2025.

  • NASA’s N+2 technology benefits include:

    • Reducing cumulative noise by 42dB below Stage 4

    • Reducing take-off and landing NOx emissions to 75% below CAEP6 levels

    • Reducing fuel burn by 50% relative to “large twin-aisle performance” (777-200LR)

    • Reducing field length by 50% relative to the

    • large twin-aisle


  • Twin-aisle aircraft represent the fastest-growing market segment

  • Growth fueled by emerging economies (Asia-Pacific, Latin America, Middle East, etc.)

Boeing Market Forecast


  • Asia-Pacific, Middle East, Latin America

  • Low Cost Carriers (LCC’s)

  • Passengers looking for cheap hub-to-hub and nonstop flights

  • Airliners looking for high capacity aircraft to meet increasing market demand


  • High-Speed Rail Systems

  • Boeing 737, Airbus A319

Sizing code progress
Sizing Code Progress

  • We used three sizing codes:

    • Simple – Incorporates design mission range, (L/D)max and number of passengers

    • Initial – Incorporates all of the above in addition to T/W and W0/S ratios.

    • MATLAB – Incorporates all of the above and the entire design mission (i.e. loiter time, emergency landing etc.)


  • Market forecasts predict a need for higher capacity aircraft to fly heavily trafficked routes

  • 400 passenger, 4000 nmi range, N+2 compliant aircraft scheduled for deployment in 2020-2025

  • Next Steps

    • Constraint Analysis

    • Sizing code refinement

    • Acquire Propulsion systems data

    • Preliminary wing design
