DASSAULT AVIATION Rafale

Rafale’s Flight Model by J.M. LANGERON Version: 4.02

General Description. Rafale is a light (10 tons) Omni-Role (AA and AG) fighter, twin engine (50 / 75kN each), with high-end weapon and navigation system (Multi target BVR, data link, Optronic sensors, Stand Off and Laser Guided AG weapons capabilities) Its advanced aerodynamic configuration and full digital flight control system provide a very high level of maneuverability. Its Speed range (750 Knots IAS , Mach 1.8) is more affordable (with supersonic capabilities without After Burner and/or with external tanks), than wide in itself (compared to Mach 2.2 of Mirage 2000-5 for example)

Versions The airframe of the Rafale is declined as of today in 4 versions:

• Rafale C : single seat, Air Force • Rafale B : two seats, Air Force • Rafale M : single seat, Navy • Rafale N : two seats, Navy

Main differences are:

• The difference between Air Force and Navy versions flight model is very light and do not need to be taken into account in F4.

• Naval versions (N,M) have only 13 hard points, when Air Force has 14.

• Naval version (N,M) front landing gear is different from the land based one, and have a landing hook.

• Two seats navy version (N) does not have internal gun (DEFA 30mm) that is on other.

Any plane of every airframe version can be operated with a given “System level”. This concept is different from the U.S. Block system: A F16-C block 40 is the frozen combination of a given airframe and system, this will not change until a complete retrofit (system and airframe). A Rafale M/F1 can be upgraded to F2 standard with only system changes. As of today, 3 standards are identified:

• F1: AA only, the today’s (20003-2004) standard of Rafale M (French Navy)

• F2: F1 AA: MICA-IR + AG stand off weapons (Scalp-EG and AASM), first standard for B and C versions (French Air Force)

F3: improved AA with Helmet Mounted Cueing System (High Offset Boreseight for MICA-IR), improved AG with Laser Guided weapons (with Damocles Pod) and Nuclear missile ASMPA, Air-Sea capabilities…
