Pilots ejected at low altitudes sometimes dying. The MiG-21PF’s ejection system needed improvement. Now gaze upon the Samolyot MiG-21PF.
This supersonic jet fighter reflects a pivotal era. It stands as a testament to Soviet engineering.
The Mikoyan-Gurevich MiG-21 is nicknamed “Fishbed” by NATO. Some fifty countries flew the MiG-21. It served many nations for a half-century. The MiG-21 set aviation records. It was the most-produced supersonic jet ever.
The MiG-21 Fishbed combined fighter and interceptor roles. It was lightweight achieving Mach 2. Its layout inspired other Soviet designs. Its shock cone and front air intake were unique. This layout had limited development potential. Space was limited for radar.
Early MiG-21 versions had short ranges. A design flaw shifted the center of gravity. This made the plane hard to control. Endurance was just 45 minutes. The MiG-21MT and MiG-21SMT variants improved range. Other performance figures worsened.
Delta wings were great for fast climbs. Turning combat caused speed loss. The MiG-21bis could climb quickly when combat-loaded. Skilled pilots and good missiles helped it against fighters. G-limits increased from +7g to +8.5g. The MiG-21 was replaced by MiG-23 and MiG-27 aircraft for ground support. The MiG-29 replaced it as a maneuvering dogfighter.
The Samolyot MiG-21PF aircraft’s simple design made it popular. Its controls engine and avionics were typical. A tail aided stability for less-skilled pilots. This enhanced its marketability abroad. Upgrades are now available for MiG-21 operators. These upgrades modernize avionics and armaments.
Over 10645 MiG-21s were built in the USSR. Moscow built single-seaters for export. Gorky built them for Soviet forces. Tbilisi made twin-seaters.
The MiG-21 has a delta wing. The fuselage is semi-monocoque. Airflow is controlled by a cone in the intake. Early models had three cone positions. Later MiG-21PF models adjusted cone position automatically. Gill slits provided extra air during takeoff.
The cabin was pressurized. Early canopies were front-hinged. The ejection seat connected to the canopy. This protected pilots during high-speed ejections. Later MiG-21PF models had canopies hinged on the side.
Three air brakes were underneath. The rear brake was blocked with an external fuel tank. JATO rockets could attach behind the wings. The tail included a vertical stabilizer and stabilator.
Most MiG-21 variants had tricycle undercarriages. Main landing gear retracted into the fuselage.
Consider the legacy of the Samolyot MiG-21PF. A simple design led to widespread use. It remains a symbol of a bygone era.
