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

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

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

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
