The Mil Mi-4 ( Russian Миль Ми-4 , NATO code name : Hound ) is a medium-sized transport helicopter developed and manufactured by Mil in the USSR .
history
In September 1951, the Soviet government decided to push the construction of helicopters. The result of this was the Jakowlew Jak-24 and the Mil Mi-4. The construction of the Mi-4 began as early as October 1951, while Mil's design was certainly based on the American Sikorsky S-55 , but without copying it. The Mi-4 is an independent construction. The first flight of the prototype, which was still equipped with a 735.5 kW (1000 PS) Schwezow ASch-62-IR star engine, took place in May 1952. For the series versions, however, a 1694 hp Schwezow ASch 82W radial engine was used, with which the Mi-4 outperformed the S-55.
The Mi-4 was shown to the public for the first time at the air show in Tuschino in 1953. At that time it received the NATO Code Type 36 , but with the introduction of the code names in 1955 it was referred to as the "Hound". The Mi-4 was manufactured in a plant in Kazan .

Production amounted to around 3500 Mi-4s built in the Soviet Union from 1953 to 1969 plus a license production of 545 Z-5s built in China from 1958/59 to 1980.
