Aerion Supersonic Business Jet FAA/UC Symposium on Aviation Noise and Air Quality Palm Springs, March 1, 2009
The Supersonic Challenge • Supersonic business jet drivers/advantages • Global economy growth • Greater user productivity • Competitive operating costs • Supersonic flight also brings problems • Higher drag results in short range, heavy aircraft • Poor subsonic and airport performance • Most civil engines don’t work in supersonic application • Sonic boom regulations restrict overland flight routes
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
Laminar Wing Concept Delta (turbulent) Unswept (laminar)
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
North Atlantic Cruise at M1.60: 4:14 Cruise at M0.90: 7:01 SSBJ Completes the Mission ~ 40% less time Paris When the SSBJ arrives in New York, the subsonic jet is still in the middle of the Atlantic New York
Anchorage New York Los Angeles Tokyo East Coast to Asia SSBJ Completes the Mission ~ 30% less time 1 hr. stop TEB – NRT 34kt headwind Supersonic mission: 9:33, includes 1:00 in Anchorage Subsonic mission: 13:06 - nonstop
NY-LA Mission At Mach 0.98 SSBJ Completes the Mission ~ 10% less time At Mach 1.1 SSBJ Completes the Mission ~ 19% less time New York Los Angeles 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
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 Reflected Wave Shock Wave 5000 ft Evanescent Wave Ground
