Aerion Supersonic Business JetMarket, Environment and Technology Richard R. Tracy Chief Technology Officer Aerion Corporation HISAC Final Conference Paris, June, 2009
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
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
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
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
Laminar Wing Concept Delta (turbulent) Unswept (laminar) HISAC Conference
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
Laminar Wing Advantages • Supersonic cruise efficiency • Subsonic cruise efficiency • Good low speed performance • Flat approach attitude HISAC Conference
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
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
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
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
Configuration HISAC Conference
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

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
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
