DRAFT Mirage IIIR description for community comment
OVERVIEW: The Mirage IIIR is a single seat, single engine, short-range, all-weather, Mach 2.0, 2nd generation reconnaissance aircraft.
DETAILS: The Mirage IIIR is a delta wing design based on the Mirage IIIE airframe. Because of the delta wing design, the Mirage III suffered from several operational limitations. Because the Mirage wing could not incorporate flaps, it required a long runways for take-off and landing. The delta wing design meant that the Mirage bled energy in a turn, limiting its ACM performance. It also suffered from buffeting at low altitude, due to the large wing area and resulting low wing loading. However, the Mirage’s wing allowed it to achieve high speed in a straight line. To maximize engine efficiency, the Mirage used two variable-section air inlets with a moveable half-cone shock cones, (called “mice”) to slow down airflow to the engines at high speed.
Developed as a dedicated reconnaissance aircraft, the Mirage IIIR lacked a radar, replacing it with up to five internally-mounted OMERA cameras encased in a purpose-developed camera nose. The aircraft retained the twin DEFA cannons and all compatibility with its external stores.
The aircraft was powered by a SNECMA Atar 9c turbojet engine turbojet engine. It produced 13,670 lb. (6200 kg) of thrust (afterburner), giving it a 0.743 Thrust-to-weight ratio under combat conditions. Also had provision for one 3308 -lb (1500 kgp) thrust SEPR 844 rocket mounted under the fuselage.
Armament included two 30 mm (1.181 in) DEFA 552 cannons with 125 rounds per gun. The Mirage IIIR also retained the capability of 4,000 kg (8,800 lb) of payload on five external hardpoints, including a variety of bombs, reconnaissance pods or Drop tanks.
Specifications:
Max Speed: 1290 knts ; 2350 km/hr; (Mach 2.2)
Max Range: 1295 nm
Max Payload: 4,000 kg on 5 hardpoints
G-limit 6.7g's max load (subsonic)
Crew: 1
NOTES: IOC: 1963. Although the Mirage IIIC retained provision for the SEPR rocket engine, it was rarely, if ever fitted in practice. The low cost of the Mirage III family helped to make it widely exported.
