Dassault Mirage 2000
The Dassault Mirage 2000 is a French multirole, single-engine fourth-generation jet fighter aircraft manufactured by Dassault Aviation. It was designed as a lightweight fighter based on the Mirage III in the late 1970s for the French Air Force (Armée de l'Air). The Mirage 2000 evolved into a multirole aircraft with several variants developed, with sales to a number of nations. The variants include the Mirage 2000N and 2000D strike variants, the improved Mirage 2000-5 and several export variants. Over 600 aircraft were built and it is in service in nine countries as of 2009.

Using the concept of the delta wing interceptor seen on the Dassault Mirage III, Dassault built a new fighter jet design. This configuration is not ideal with regard to maneuverability, low-altitude flight, and distance required for take-off and landing, but has advantages in high-speed flight characteristics, simplicity of construction, low radar signature and internal volume.

Features

The Mirage 2000 features a low-set thin delta wing with cambered section, 58 degrees leading-edge sweep and moderately blended root; area-ruled; two small canard wings, fixed, placed just behind the air intakes. The flight controls on the wings are: four elevons (+15/-30°), four slats.

Its neutral point is in front of its center of gravity, giving the fighter relaxed stability to enhance maneuverability. It was the first fighter jet to incorporate negative stability and fly-by-wire controls in its design. An airbrake is fitted above and below each wing in an arrangement very similar to that of the Mirage III. A noticeably taller tailfin allows the pilot to retain control at higher angles of attack, assisted by the small strakes mounted along each air intake.

A runway arresting hook or a fairing for a brake parachute can be fitted under the tail. The landing roll is reduced by robust carbon brakes. The backward-retracting, steerable nose gear features dual wheels, while the main gear features single wheels and retracts inward into the wings.

A fixed removable refueling probe can be attached in front of the cockpit, offset slightly to the right of center.

Structure

Multi-spar metal wing; elevons have carbon-fiber skins with AG5 light alloy honeycomb cores; carbon-fiber/light alloy honeycomb panel covers avionics bay; most of the tailfin and all of the rudder are skinned with boron/epoxy/carbon; the rudder has a light alloy honeycomb core.

Flight control system

The aircraft has a redundant fly-by-wire automatic flight control system, providing a high degree of agility and easier handling, together with stability and precise control in all situations. The fighter's airframe is naturally unstable, and so it is coupled with FBW commands to obtain the best agility; however, in override mode it is still possible to exceed a 270 deg/sec roll rate and allows the aircraft to reach 11 g (within the 12 g structural limit), instead of 9 g when engaged. The system is reliable with no known losses due to its failure.

Landing gear

The aircraft uses a retractable tricycle type landing gear by Messier-Dowty, with twin nosewheels and a single wheel on each main gear. Hydraulic retraction, nosewheels rearward, main units inward. Oleo-pneumatic shock absorbers. Electrohydraulic nosewheel steering (+/-45 degrees). Manual disconnect permits the nosewheel unit to caster through 360 degrees for ground towing. The landing roll was reduced by using robust carbon brakes.

Cockpit

The fighter is available as a single-seat or two-seat multi-role fighter. The pilot flies the aircraft by means of a centre stick and left hand throttles, with both incorporating hands-on-throttle-and-stick (HOTAS) controls. The pilot sits on a SEM MB Mk10 zero-zero ejection seat (a license-built version of the British Martin-Baker Mark 10). Unlike in the F-16, the pilot sits in a conventional position, without the steep backward slope of the F-16 seat. The cockpit is quite small, and there is no bubble canopy. Despite this, the cockpit visibility is quite good, but less than the F-16, especially in the 'six o'clock' (rearwards-looking) position.

The instrument panel (in the Mirage 2000 C) is dominated by a Sextant VE-130 Heads Up Display which presents data relating to flight control, navigation, target engagement and weapon firing, and the VMC-180 radar screen located centrally below it. To the lower left is a stores management panel, above which are the navigation instruments and altimeter. The right half of the instrument panel accommodates the engine and systems displays. Located on the left side of the cockpit, just ahead of the throttle, are controls for the communications equipment, including the Have Quick secure radio.

Avionics

Avionics for the Mirage-2000B/C include the Sagem ULISS 52 inertial navigation system (INS), TRT radio altimeter, Dassault Electronique Type 2084 central digital computer, Digibus digital data bus and Sextant Avionique Type 90 air data computer. The communication equipment package includes the LMT NRAI-7A IFF transponder, IO-300-A marker beacon receiver, TRT ERA 7000 V/UHF com transceiver, TRT ERA 7200 UHF or EAS secure voice communications.

Radar

Thomson-CSF RDM multi-mode radar or Dassault Electronique/Thomson-CSF RDI pulse-Doppler radar for the Mirage 2000C/D, each with an operating range of 54 nm (100 km / 62 miles). This unit was an evolution of Cyrano radars, with more modern processing units and look-down/shoot-down capabilities. The effective range is around 60–70 km with modest capabilities against low-level targets. It is linked with Super R.530F missiles, and equipped the first 37 aircraft delivered to the French Air Force and most exported Mirages. It has multirole capabilities that enable its use in air-to-surface tasks, including anti-ship roles. The very early RDM were still not linked with the Super R.530F missiles, but it was solved quickly. Some recent export versions of the aircraft carry the Thales RDY (Radar Doppler Multitarget) developed for the Mirage 2000-5.

Countermeasures

The Mirage 2000 is equipped with the Thales Serval Radar warning receiver (RWR) with antennas on the wingtips and on the rear of the top of the tailfin. It is also equipped with the Dassault Sabre RF jammer in a pod below the bottom of the tailfin, with the antenna in a fairing on the front of the tailfin. The Dassault Éclair dispenser system under the tail was eventually replaced by a pair of Matra Spirale dispensers, each fitted on the extensions behind the rear of each wingroot, giving a total capacity of 224 cartridges.

Engines

The new and powerful SNECMA M53 afterburning bypass turbojet engine was developed for the ACF, and was available for the Mirage 2000 project. The Mirage 2000 is equipped with a SNECMA M53-5 (first 37 airplanes), or SNECMA M53-P2 low-bypass ratio turbofan engine, depending on the aircraft version, which provides 64 kilonewtons (14,000 lbf) of thrust dry and 98 kilonewtons (22,000 lbf) in afterburner. The air intakes are fitted with an adjustable half-cone-shaped centerbody, which provides an inclined shock of air pressure for highly efficient air intake. Total internal fuel capacity is 3,978 litres (1,051 US gal) in the Mirage 2000C and E, and 3,904 litres (1,031 US gal) in the Mirage 2000B, N, D and S. There are also provisions for a jettisonable 1,300-litre (340 US gal) centerline fuselage fuel tank and for a 1,700-litre (450 US gal) drop tank under each wing.

Armament and payload

The Mirage 2000 is equipped with built-in twin DEFA 554 (now GIAT 30–550 F4) 30 mm revolver-type cannons with 125 rounds each. The cannons have selectable fire rates of 1,200 or 1,800 rounds per minute. Each round weighs 275 grams (9.7 oz) and has a muzzle velocity of around 800 metres per second (2,600 ft/s).

The Mirage 2000 can carry up to 6.3 tonnes (14,000 lb) (or 7 tonnes for −9 version) of stores on nine pylons, with two pylons on each wing and five under the fuselage. External stores can include Matra Super 530 medium-range semi-active radar-guided air-to-air missile on the inboard wing pylons and underbelly, and Matra Magic short-range infrared-seeking AAM on the outboard wing pylons. Other short-range missiles such as the AIM-9J/L/P are compatible and are often used on Mirages which have been exported, because Magic itself was meant as 'Sidewinder compatible'. The Mirage 2000C and later versions can carry the lighter, more advanced MBDA MICA instead of the Super 530D.
