Outline Mission Statement Market Competition Concept of Operations Design Requirements Design Comparison New Technologies and Advanced Concepts Sizing Code Summary
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
Market • Twin-aisle aircraft represent the fastest-growing market segment • Growth fueled by emerging economies (Asia-Pacific, Latin America, Middle East, etc.) Image Source: Boeing Market Forecast
Customers • 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
Competition • High-Speed Rail Systems • Boeing 737, Airbus A319 Map of proposed high-speed rail systems in China, along with estimated travel times from Beijing Image Source: www.hasea.com
Concept of Operations • Operational City Pairs Reference: Centre for Asia Pacific Aviation
Concept of Operations • Design Mission • 400 Passengers (Max Payload) • 4,000 nmi Range (Tokyo-NHD to New Delhi-DEL: 3,200nmi) • Runway Length • 8,300 ft (Takeoff) 200 nmi 4000 nmi
Design Requirements *Reference Vehicle B737-700

New Technologies and Advanced Concepts PROPULSION • Geared Turbofan • Unducted Fan (UDF) • Bio-Diesel • Trailing Edge Brushes • Blended Wing Body • Spiroid Winglets AERODYNAMICS
New Technologies and Advanced Concepts Dynamics & Controls • Fly By Wireless • Morphing Trailing Edge • Composites • Bonded Skin Panels Structures
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.)
Summary • 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
