  2. Supersonic Design Dichotomy • Two approaches to civil supersonic flight: • Low sonic boom is the primary goal of most programs • Maximum fuel efficiency and operatinal flexibility are Aerion goals, with boom reduction secondary • FAA and ICAO require compliance in either case with airport noise and engine emissions regulations 7/14/11 ¡ 2 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡

  3. Aerion Design Criteria • Best possible supersonic cruise efficiency & range • Equal or greater range at high subsonic speed • Current production proven engine and systems • Operationally similar to subsonic aircraft • Mach 1.6 minimizes technical and business risk 7/14/11 ¡ 3 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡

  4. Sonic Boom Approaches • Low Boom – Some time savings over populated areas – Pending “low boom” regulations and design technology • No Boom – Maximize cruise range and efficiency – Meet all current regulations (sonic boom, noise, emissions) – Supersonic “boom cutoff” overland, when permitted 7/14/11 4 Aerion Brief - FAA Conference

  5. “Boom Cutoff” Over Populated Areas • Current – FAA: Mach 1 or less over U.S.A. – ICAO: “No unacceptable situation on the ground” (no boom?) • Aerion complies with both rules – Efficient subsonic flight over US – No boom at Mach 1.1+ where permitted Reflected Wave Shock Wave 5000 ft Evanescent Wave Ground 5 ¡ 7/14/11 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡

  6. Traditional Approach • Delta Wing – Lower lift-related drag at supersonic cruise – High sweep, short span and less effective flaps • Result – Longer runways and high angle of attack – Less efficient at SS cruise and high subsonic speed 7/14/11 ¡ 6 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡

  7. Aerion Technology • Laminar Flow Wing – Lower overall supersonic drag – Low sweep and powerful flaps • Additional Benefits – Shorter runways and flat approach – More efficient subsonic cruise 7/14/11 ¡ 7 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡

  8. Laminar ¡Flow ¡Valida>on ¡ • F-15 tests at NASA Dryden 1999-08 • Full-chord natural laminar flow (NLF) • New F-15 tests underway since 2010 • Flow calibration and larger surface • European Transonic Wind Tunnel (ETW) • Achieved full chord NLF to 30 million Reynolds no. 7/14/11 ¡ 8 ¡ Aerion ¡Brief ¡-­‑ ¡FAA ¡Conference ¡
