Aerion Supersonic Business Jet FAA Civil Supersonic Aircraft Panel Discussion Baltimore, April 21, 2010

2 The Supersonic Challenge Supersonic business jet mission –To place a high-value team where they are needed in the shortest possible time. To do this successfully requires an aircraft with –The best possible supersonic cruise efficiency –Good performance at all speeds: landing, subsonic, supersonic –Flexibility to perform both short range and long range missions –Ability to comply with all existing and proposed regulations
3
3 Traditional Approach Delta Wing adopted for supersonic cruise because of its… –Better supersonic lift-related drag (but still worse than subsonic) –Favorable wing structure and fuel arrangement However, it imposes severe handicaps due to... –High sweep, short span and ineffective flaps, resulting in… Poor low speed and transonic performance, thus… –Long runways and high angle of attack –Inability to fly below Mach 1 efficiently for overland legs –Lack of flexibility for short range operations from business airports

4 The Aerion Solution
5
5 Laminar Wing Concept Unswept (laminar) Delta (turbulent)
6
6 Laminar Wing Advantages Significantly reduces cruise fuel burn Uses same airports as large subsonic business jets Efficiently cruises just below Mach 1 Cruises below 51,000ft avoiding ozone layer Aerion approach attitude

7 North Atlantic Cruise at M1.60:4:14 Cruise at M0.90: 7:01 New York Paris When the SSBJ arrives in New York, the subsonic jet is still in the middle of the Atlantic SSBJ Completes the Mission ~ 40% less time
8
8 East Coast to Asia Tokyo Anchorage New York Los Angeles TEB – NRT 34kt headwind Supersonic mission: 9:33, includes 1:00 in Anchorage Subsonic mission: 13:06 - nonstop 1 hr. stop SSBJ Completes the Mission ~ 30% less time
9
9 NY-LA Mission TEB – LAX 41kt headwind Cruise at M = 0.98: 4:19 Cruise at M = 1.10: 3:52 Cruise at M = 0.90: 4:45 New York Los Angeles At Mach 0.98 SSBJ Completes the Mission ~ 10% less time At Mach 1.1 SSBJ Completes the Mission ~ 19% less time
10
10 Sonic Boom FAA – Mach 1 or greater prohibited ICAO – “No unacceptable situation on the ground” (no or low boom) Aerion complies with existing regulations –Efficient flight at 0.98 Mach over US –Boom cutoff flight ~1.15 Mach with no boom on the ground Shock Wave Reflected Wave Evanescent Wave 5000 ft Ground
