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

HISAC Conference 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 of flying supersonic over populated areas, versus… Weight and cost increase, along with adverse “green” impact Route restrictions to 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

Aerion’s Approach

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

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

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 Shock Wave Reflected Wave Evanescent Wave 5000 ft 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 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 New York Los Angeles

HISAC Conference 20 Range High Speed Cruise Subsonic 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 Conclusions Minimum SSBJ environmental impact : NLF Low Drag Airframe Less Required Thrust Smaller Engine Lower Fuel Burn SSBJ Lowest Environmental impact No Boom Overland Flight No Boom Overland Flight
