The Mil Mi-1 (USAF/DoD reporting name "Type 32", NATO reporting name "Hare") was a Soviet three- or four-seat light utility helicopter. It was the first Soviet helicopter to enter serial production. It is powered by one 575 hp (429 kW) Ivchenko AI-26V radial. It entered service in 1950 and was first seen on the 1951 Soviet Aviation Day, Tushino and was produced for 16 years. More than 1,000 were built in the USSR and 1,594 in Poland, as SM-1.
Mikhail Mil began work on rotary-winged aircraft before 1930, but the Mi-1, first his production helicopter, was begun in 1946, under a designation EG-1. In 1947 Mil became a head of OKB-4 design bureau in Tushino, and works were intensified. A final design was named GM-1 (for Gyelikopter Mila, Mil's Helicopter).Soviet engineers tried to create a completely original design. So, they made a rotor hub with spaced vertical and horizontal hinges. This design increased the efficiency of helicopter control and was much simpler than that used on American helicopters. The prototype completed first free flight on 20 September 1948 (pilot Mikhail Baikalov). In 1949 it went through official state trials. Despite crashes of two prototypes, the design was an overall success, and after further work, was ordered for a production, under a new designation Mi-1, for Mil initials. The production was initially limited - the first series of only 15 machines was ordered on 21 February 1950, in factory No.3 in Moscow. Only after presentation to Joseph Stalin in 1951, the authorities decided to increase production. In 1952–1953, 30 Mi-1s were manufactured in Kazan, and from 1954 a mass production started in Orenburg and from 1956 in Rostov (current Rostvertol). The design was a subject of further improvements during production, mostly increasing reliability. Especially a rotor technology was changing. Period between repair increased to 300 hours in Mi-1T (hence a letter T for trekhsotchasovoi, 300-hour), 600 in Mi-1A, then to 1,000 and 3,000 hours by the end of production.
