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 dont 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

The Aerion Solution

Laminar Wing Concept
Delta (turbulent)?
Unswept (laminar)?
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
