FAA Civil Supersonic Aircraft Panel Discussion

Baltimore, April 21, 2010


The supersonic challenge
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

2


Traditional approach
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
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

1 hr. stop

TEB – NRT 34kt headwind

Supersonic mission: 9:33, includes 1:00 in Anchorage

Subsonic mission: 13:06 - nonstop


Ny la mission
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
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
