The Soviet Mikoyan-Gurevich I-75 ( Russian Микоян-Гуревич И-75 ) was a heavy interceptor for the all-weather area from the second half of the 1950s. Designed as a rival design to the Sukhoi Su-9 or T-43, it could not prevail against them and therefore did not go into series production. Even so, at 2,300 km / h it was the fastest jet-powered aircraft in the USSR in its day .
development
The design of the I-75 was based on the I-7 from the mid-1950s, which is why it was initially named I-7U . Visually, the I-75 corresponded to an enlarged version of the E-2A, one of the early prototypes of the MiG-21 . The wings were taken over from the MiG-19 and had a leading edge sweep of 55 ° and two large boundary layer fences. The tail of the middle decker was also swept. The Ljulka-AL-7F-1 engine installed in the fuselage was supplied with air through an inlet duct beginning in the bow. The Uragan 5B radio measuring device was also located in the bow, in the shock wave diffuser of the central air intake. The horizontal stabilizer was designed as a pendulum rudder and there was a rear warning device in the vertical stabilizer, and the automatically adjustable thrust nozzle was also located in the rear. The armament consisted of two air-to-air missiles at lower wing stations in accordance with the Soviet military doctrine in force at the time. The two automatic cannons had been left out.
The flight test of the machine, which was ultimately renamed I-75F , was carried out in 1957 by F. I. Burzew and provided some knowledge about the behavior of swept wing aircraft at high speeds. In its time, it was the fastest Soviet aircraft with a pure TL drive. The delta wing record aircraft Je-150 and Je-152 emerged from the I-75F .
