Description

Soviet MiG-21 ranks among the most widely spread and reknown aeroplane fighters. It has the same surprise for the world as its famous predecessor MiG-15. When the A. I. Mikojan's designing team was working on the new draft of aeroplane with the speed approaching M2, hardly anybody could anticipate that the structural conception following the easy control, reliability, speed and ability to fulfil challenging combat missions will again be victorious, this time in the form of MiG-21. In 1955 the first take-off of the new conception E-2 aeroplane with one engine and slender swept-back wings was accomplished. On June 16, 1956 the test pilot Sedov performed the test flying of E-4 aeroplane being in fact E-2A equipped with delta wing featuring more suitable aerodynamic properties. Via further prototypes E-5, E-6 and after various modifications innovations the aeroplane came to large production. Primarily in MiG-21F versions, which were the machines designed chiefly for missions under conditions of good visibility. Gradually equipped with more modern outfit and equipment and more intricate mechanism of wing MiG-21 passed from Ye. PFM, S, M versions up to present most modern variants MiG-21 MF, SMT and bis. The MiG-21 forms to date a backbone of air fleets in many countries of the world on various continents. The combat christening underwent in Vietnamese wars during the defence of towns and premises and, later on, also on Sinai peninsula in 1967 and 1973. The licence for the production of these aeroplanes was purchased, among others, by India where MiG-21 fighters took part in the conflict with Pakistan in 1971. By record versions bearing the designation E-66, E-66A, E-33, E-76 a number of international records acknowledged by FAI was beaten (e.g. in 1959 G. K. Mosolov reached maximum speed of 2 388 km/hr on E-66, in 1961 the altitude of 34 714 m on E-66A). MiG-21 was also used in various experiments for example with lift-thrust engines behind the cockpit to test the wings for Tu-144 and the like. MiG-21 MF is one-seater single-engined aeroplane with delta wing and floating horizontal tail surfaces. The fuselage of circular cross-section, semi-shell construction with asserted rule of surfaces consists of three parts. The entrance of air is controlled by adjustable cone covering the radar aerial; the upper part of fuselage also contains the radio-electronic device; the pilot's cockpit is equipped with ejection seat KM-1 allowing the rescue in zero altitude. The cockpit enclosure swings to the left side. The fuselage also contains pits for landing gear, fuel tanks and jet engine turbine R-13-300 having 50 kN take-off thrust, with afterburning on 64.8 kN thrust. Under the fuselage is the two-barelled gun GS-23 calibre 23 mm. The fuselage superstructure behind the cockpit contains the systems of control and radionavigational equipment. The delta all-metal wing is equipped with wing flaps and ailerons. Installed in it are the fuel tanks and some parts of radioelectronic equiment. The tail surfaces consist of floating horizontal tail surfaces and vertikal tail area, in which the radio aerials, identification equipment, warning system, etc. are built in. The landing gear with nose wheel is retracted hydraulically. To reduce landing run the brake parachute launched from the container under the vertical tail area is used. The aeroplane is able to operate even under reduced visibility and by night thanks to rich equipment of radionavigative instruments. Four suspensions under the wings and one under the fuselage are designed for the suspension of various combinations of armament as for example beam-rider and non-guided rockets, blocks with non-guided rockets, bombs of variuss mass, additional tanks, etc. MiG-21 SMT and bis is a result of further development of MiG-21 MF. MiG-21 SMT has extended fuselage tanks and thereby increased superstructure behind the cockpit. MiG-21 bis equipped with new jet engine R-25-300 with 93.5 kN maximum thrust, has extended fuselage fuel tanks, new navigation system and may carry beam-rider rockets of the most modern types.
