Mikoyan-Gurevich MiG-1
Encyclopedia : M : MI : MIK : Mikoyan-Gurevich MiG-1
The Mikoyan-Gurevich MiG-1 (Микоян-Гуревич МиГ-1) was a Soviet fighter aircraft of World War II. Although difficult to handle, it formed the basis for the MiG-3, which proved to be a capable high-altitude interceptor aircraft and established a reputation for its designers.
The MiG-1 was designed in response to a requirement for a fighter with inline engine perceived by the Soviet Air Force in January 1939. Initially the aircraft, named I-200, was designed in Polikarpov construction bureau. The works started in June 1939, under direction of Nikolai Polikarpov and his assistant M. Tetivikin. Polikarpov himself preferred radial engines, and promoted his I-180 design at that time, but when powerful Mikulin AM-37 inline engine became available, he decided to use it in a fighter. The approach that he selected was to build the smallest possible aircraft around the intended powerplant, thereby minimising weight and drag - the philosophy of the light fighter. As specified, the aircraft was to be capable of reaching 670 km/h (417 mph). In August 1939, Polikarpov made N. Andrianov a leading designer. At that time, Polikarpov fell out of favour with Stalin. As a result, when Polikarpov went in November 1939 to tour of the German aviation works, the Soviet authorities decided to scatter his construction team and create new Experimental Construction Section (OKO), headed by Artem Mikoyan and Mikhail Gurevich, formally still subordinated to Polikarpov bureau until June 1940. Further works upon the I-200 design were given to Mikoyan and Gurevich, who later became, not fully justly, recognized as its designers.
The result was a highly conventional aircraft that flew on schedule on April 5 1940, although its intended powerplant was not ready in time. Instead, the new fighter flew with the less powerful AM-35, and even with this soon broke the Soviet air speed record by 40 km/h (25 mph). It could not, however, attain the speed originally specified by the air force with this engine. The I-200 was put into production almost immediately, on May 31, 1940. Contrary to other competing designs: I-26 (Yak-1) and I-301 (LaGG-3), the I-200 successfully completed the state trials in August at the first attempt. By the end of the year, the type was already being delivered to test squadrons. Here, it was discovered that the high wing loading of the small aircraft produced some very nasty handling problems, including tendencies towards both stalling and spinning, and a lack of directional stability.
As reports of the handling problems came back to Mikoyan and Gurevich, they worked to remedy them, incorporating many design changes. They also increased aircraft range, by increasing fuel tanks. Improved plane was flown on October 29, 1940. From 9 December 1940, according to a new naming system, the first 100 I-200 were named MiG-1, after Mikoyan and Gurevich initials, while further improved aircraft, were named MiG-3.
