  1. Aerion Supersonic Business JetMarket, Environment and Technology Richard R. Tracy Chief Technology Officer Aerion Corporation HISAC Final Conference Paris, June, 2009

  2. Supersonic Dichotomy • Two approaches to civil supersonic flight have emerged since the Concorde. • Low sonic boom is the goal of most programs, with increased range secondary • Maximum range and flexibility is Aerion’s focus, with no compromise for boom reduction • HISAC stimulates a comparative assessment of the problems and benefits of both approaches HISAC Conference

  3. Market Issue • Value offlying supersonic over populated areas, • versus… • Weight and cost increase, along with adverse “green” impact • Route restrictionsto corridors, and “superboom” avoidance • Delayed availability by five to ten years • Uncertainty whether low boom will be approved HISAC Conference

  4. Aerion Goals • “Uncompromised” supersonic cruise efficiency • Strong emphasis on subsonic performance • Current production engine and systems • Practical, operationally flexible aircraft • Low business and technological risk • First to market HISAC Conference

  5. Traditional Approach • Delta Wing • Least supersonic lift-related drag • High sweep, short span and ineffective flaps • Result • Longer runways and high angle of attack • Less efficient subsonic cruise HISAC Conference

  6. Aerion’s Approach

  7. Laminar Wing Concept Delta (turbulent)‏ Unswept (laminar)‏ HISAC Conference

  8. NLF Laminar Wing Advantages:The Virtuous Cycle Lower Fuel Burn • Lower drag requires… • Less thrust, allowing… • Smaller engine and • Less fuel Smaller Engine Low Drag Airframe Less Thrust Required HISAC Conference

  9. Laminar Wing Advantages • Supersonic cruise efficiency • Subsonic cruise efficiency • Good low speed performance • Flat approach attitude HISAC Conference

  10. Laminar Flow Validation • F-15 flight test at NASA Dryden • Demonstrated SSNLF to >10 million • Test article full chord • NLF test at ETW • Demonstrated SSNLF to 30 million • Test article full chord • Aerodynamic full scale • Level required for Aerion performance HISAC Conference

  11. Sonic Boom: Considerations • Current • FAA: prohibits Mach 1 or greater over U.S.A. • ICAO: “No unacceptable situation on the ground” • Aerion complies with existing regulations • Efficient below Mach 1 over US • No boom at ~Mach 1.15 elsewhere Reflected Wave Shock Wave 5000 ft Evanescent Wave Ground HISAC Conference

  12. Sonic Boom:Different Approaches • Low Boom • Market appeal ? • Increase weight and fuel • Regulation changes • High Performance (No Boom) • Maximize cruise efficiency • Meet all current regulations • Supersonic “boom cutoff” potential HISAC Conference

  13. Supersonic Overland:NY-LA Mission New York Los Angeles TEB – LAX 41kt headwind G-V at M=0.85: 5:00 Aerion at M=0.98: 4:19 Aerion at M=1.10: 3:52 HISAC Conference

  14. Design Overview

  15. Configuration HISAC Conference

  16. P&W JT8D-219 Engine • Existing certified commercial engine • MD-80 series aircraft • Mature and reliable • Improvements to meet latest emission standards • Noise-compliant • Fuel efficient • Aerion low drag airframe is a unique fit for the JT8D HISAC Conference

  17. Major Systems Fuel Tank APU Engines Fuel Tanks Avionics & Fly-By-Wire Flight Control Systems ECS HISAC Conference

  18. Interior HISAC Conference

  19. Performance

  20. Range Subsonic Cruise High Speed Cruise Boom Cutoff Cruise HISAC Conference

  21. Economics Operating Expense per NM, 550 hrs/yr Utilization * * Data from Business & Commercial Aviation 2006 Operations Planning Guide HISAC Conference

  22. Conclusions • Aerion SSBJ offers economics, operating characteristics and flexibility on a par with subsonic aircraft • Maximum efficiency sub- and supersonic cruise results from NLF wing and no compromise for low boom • Compliance with existing regulations reduces program risk • First to market HISAC Conference

  23. NLF Conclusions Lower Fuel Burn SSBJ Low Drag Airframe Smaller Engine • Minimum SSBJ environmental impact : Less Required Thrust No Boom Overland Flight Lowest Environmental impact HISAC Conference
