Artem Mikoyan - Jet Aircraft Designs

Jet Aircraft Designs

Early post-war designs were based on domestic works as well as captured German jet fighters and information provided by Britain or the US. By 1946, Soviet designers were still having trouble in perfecting the German-designed, axial-flow jet engine, and new airframe designs and near-sonic wing designs were threatening to outstrip development of the jet engines needed to power them. Soviet aviation minister Mikhail Khrunichev and aircraft designer Alexander Sergeyevich Yakovlev suggested to Joseph Stalin that the USSR buy advanced jet engines from the British. Stalin is said to have replied: "What fool will sell us his secrets?" However, he gave his assent to the proposal, and Artem Mikoyan, engine designer Vladimir Klimov, and other officials traveled to the United Kingdom to request the engines. To Stalin's amazement, the British Labour government and its pro-Soviet Minister of Trade, Sir Stafford Cripps were willing to provide technical information and a licence to manufacture the Rolls-Royce Nene centrifugal-flow jet engine. This engine was reverse-engineered and produced in modified form as the Soviet Klimov VK-1 jet engine, later incorporated into the MiG-15 (Rolls-Royce later attempted to claim £207m in licence fees, without success).

In the interim, on April 15, 1947, Council of Ministers issued a decree #493-192, ordering the Mikoyan OKB to build two prototypes for a new jet fighter. As the decree called for first flights as soon as December of that same year, the designers at OKB-155 fell back on an earlier troublesome design, the MiG-9 of 1946. The MiG-9 suffered from an unreliable engine and control problems.

The I-270, a prototype based on German concepts, developed into the I-310 in the USSR and into F-86 Sabre in the States. With the Klimov version of the British Nene jet engine, this design became the MiG-15, which first flew on December 31, 1948. Despite its mixed origins, this aircraft had excellent performance and formed the basis for a number of future fighters. The MiG-15 was originally intended to intercept American bombers such as the B-29 Superfortress, and was even evaluated in mock air-to-air combat trials with interned ex-U.S. B-29 bombers as well as the later Soviet B-29 copy, the Tupolev Tu-4. A variety of MiG-15 variants were built, but the most common was the MiG-15UTI (NATO 'Midget') two-seat trainer. Over 18,000 MiG-15s were eventually manufactured, then came the MiG-17, and MiG-19.

The MiG-15s were the jets used during the Korean War by Communist forces, and "MIG Alley" was the name given by U.S. Air Force pilots to the northwestern portion of North Korea, where the Yalu River empties into the Yellow Sea. During the Korean War, it was the site of numerous dogfights between U.S. fighter jets and those of the Communist forces, particularly the Soviet Union. The F-86 Sabre and the Soviet-built MIG-15 'Fagot' were the aircraft used throughout most of the conflict, with the area's nickname derived from the latter. Because it was the site of the first large-scale jet-vs-jet air battles, MIG Alley is considered the birthplace of jet fighter combat.
