Aerion Supersonic Business Jet

FAA Civil Supersonic Aircraft Panel Discussion Baltimore, April 21, 2010

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

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
