  1. Where NASA is going….

  2. Environmentally Friendly Aircraft Smog-free Noise within airport boundaries Minimize the contribution of air vehicles to the production of smog Constrain objectionable noise to within airport boundaries No impact on global climate Minimize the impact of air vehicles on global climate

  3. Air Vehicles for New Missions Space exploration Earth science Develop innovative air vehicles for science missions in the atmosphere of other planets Use innovative air vehicles to conduct autonomous earth science missions

  4. Transformation of NASA Aeronautics….

  5. Goal: • Demonstrate barrier-breaking vehicle concepts, beyond the scope of conventional air vehicles, that protect the Earth’s environment and enable science missions. • Approach: • Develop technologies and demonstrate them in flight to provide evidence of barrier breakthroughs. • Benefits: • Opens more communities to air transportation • Enables new air transportation models by doubling vehicle speed capability • Eliminates aviation pollution • Enables new science platforms

  6. Demonstration Projects SUBSONIC NOISE REDUCTION — Demonstrate a 50% noise reduction compared to 1997 state of the art. SONIC BOOM MITIGATION — Demonstrate technology to enable overland supersonic flight. HIGH ALTITUDE LONG ENDURANCE (HALE) AIRCRAFT — Demonstrate a 100-day duration high-altitude, fixed wing, unmanned aircraft. ZERO EMISSIONS AIRCRAFT — Demonstrate technology to enable alternative power aircraft.

  8. Subsonic Noise Reduction Demonstration Keep noise within airport boundaries

  9. Noise Reduction Approaches Airframe Noise Reduction (Slats, flaps, gears) High Noise Regions Low Noise Flight Procedures (Continuous descent approach, low noise guidance) Continuous mold line flap and slat cove filler Baseline Jet Noise Reduction (Advanced chevrons, vortex breakdown control, offset fan flow) Fan Noise Reduction (Forward swept fan, porous stators, variable area fan nozzle)

  10. Sonic Boom Reduction Demonstration

  11. Sonic Boom Reduction Demonstration Defining an acceptable sonic boom level

  12. Shaped Sonic Boom Demonstration Predictions Demonstrate a shaped sonic boom that persists to the ground Mach 1.4 32,000 feet Modified F-5 Overpressure Modified F-5 F-5E Profile View Time Fuselage Cross-Sections Bottom View

  13. F-5SSBD F-5E First Ever Shaped Sonic Boom Recorded August 27, 2002 Signatures recorded during SSBD back-to-back data flights in the Edwards AFB supersonic flight corridor early morning Flight conditions: Mach 1.36+, Altitude 32,000 ft Design Mach 1.4

  14. Elements of Demonstration Plan Data Generation Demonstrator Goal Planning Technical Regulatory National Goal Integrated Tech X-Plane FAA & ICAO Coordination Identifying Techs To Overcome Barriers Safe, Efficient, Quiet, Supersonic Flight EPA, ATM, Public Acceptance Testing Key Tech Ground Demos RemoveProhibition Defining Demo Requirements & Approaches Operational Experience Precursor Tech Demos

  15. Zero Emissions Demonstration A Leap Forward in Emissions Reduction

  16. Zero Emissions Attributes Maximum payoff to Goals Hydrogen fueled Zero CO2 Other technologies might achieve a 10-20% reduction in pollutants – this approach gets a 100% reduction. Fuel Cell Energy Conversion Zero NOx High energy efficiency Electric drive Lowest noise The zero emissions system delivers maximum benefit towards public good goals; nothing else comes close
