Mirage2000:The Cutting Edge

  The Cockpit of a Mirage 2000-5 with HUD display
   The SNECMA M53-P2 turbofan engine 98 kN thrust with afterburn.
                            Low-set thin delta wing with cambered* section, 58 degrees leading-edge sweep and moderately blended root; area-ruled; capable of carrying four air-to-air missiles.
(Camber: the asymmetry between the top and bottom curves of an aerofoil)
                            The aircraft's center of lift** was moved in front of its center of gravity, giving the fighter a degree of instability that enhances maneuverability.
(An aircraft's center of lift* is the location at which the net lift produced by all airfoils is located. With the center of mass, it is an important factor in the performance and stability of an aircraft).
                             A runway arresting hook or fairing for a brake parachute can be fitted under the tail. The landing roll was 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.
                            An airbrake is fitted on top of 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 small strakes mounted along each air intake.
                            First fighter jet with negative static stability.

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.

COCKPIT
Mirage 2000-5 is available as a single-seater or two-seater multi-role fighter. The aircraft has Hands-On Throttle and Stick (HOTAS) control. Mirage 2000-5 incorporates the Thales VEH 3020 head-up display and five cathode ray tube multifunction advanced pilot systems interface (APSI) displays.
Instrument Panel:The combined head-up / head-level display is collimated at infinity, and presents data relating to flight control, navigation, target engagement and weapon firing. Sensor and system management data is presented on two coloured lateral displays.The instrument panel is dominated by a Heads Up Display (HUD) with the VMC 180 radar screen located centrally below it. To the lower left is a stores management panel. Above the stores management panel are the navigation instruments and altimeter. The right half of the instrument panel houses 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
Standard avionics for the Mirage-2000B/C include:
Sagem ULISS 52 inertial navigation system (INS), TRT radio altimeter.
Sextant TMV-980 data display system (VE-130 head-up and VMC-180 head-down) (two head-down in 2000N/D). The combined head-up/head-level display is collimated at infinity, and presents data relating to flight control, navigation, target engagement and weapon firing. Sensor and system management data is presented on two colored lateral displays.
Dassault Electronique Type 2084 central digital computer, Digibus digital databus (2084 XR in 2000D) and Sextant Avionique Type 90 air data computer.
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 and TARGETING
Thomson-CSF RDM multi-mode radar or Dassault Electronique/Thomson-CSF RDI pulse-Doppler radar for Mirage 2000C/D, each with operating range of 54 nm (100 km / 62 miles).
Dassault/Thales Antilope 5 Radar with terrain avoidance capability for Mirage 2000N Nuclear Strike variant.
The Thales multimode RDY (Radar Doppler Multitarget) developed for Mirage 2000-5.

Mirage 2000 has an upgraded digital Weapon Delivery and Navigation System (WDNS). The aircraft can be fitted with a TV/CT CLDP laser designation pod from Thales Optronique, which provides the capability to fire laser-guided weapons by day and night. The 2000-5 Mk 2 will have the Damocles laser designation pod with thermal imaging camera, also from Thales Optronique.
Mirage 2000-5 is equipped with a multi-mode Thales RDY doppler radar which provides multi-targeting capability in the air defence role and the radar also has look down / shoot down mode of operation. The radar can simultaneously detect up to 24 targets and carry out track while scan on the eight highest priority threats.
 
COUNTERMEASURES
The aircraft is equipped with a self-protection suite installed internally. Mirage 2000-5 carries the ICMS Mark 2 automated integrated countermeasures system from Thales.
ICMS Mark 2 incorporates a receiver and associated signal processing system in the nose section for the detection of missile command data links. The system can be interfaced to a new programmable mission planning and a post-mission analysis ground system.
Thales Serval Radar warning receiver* (RWR) with antennas on the wingtips and on the rear of the top of the tailfin.
(Typically fitted to military aircraft, radar warning receivers (RWR) detect the radio emissions of radar systems, whether ground-based or on-board other aircraft. The system is often capable of classifying the source of the radar by type (Pulsed or continuous wave radar, for example) and strength. It may be further capable of using this data to identify the type of threat the detected radar poses, e.g. an incoming radar-guided surface-to-air missile)
Dassault Sabre RF jammer in a pod below the bottom of the tailfin, with an antenna in a fairing on the front of the tailfin.
Dassault Eclair dispenser system under the tail. This was eventually replaced by a pair of Matra Spirale dispensers.
