Description
The Mil Mi-4 (USAF/DoD reporting name "Type 36", NATO reporting name "Hound") is a Soviet transport helicopter that served in both military and civilian roles. The Mi-4 was designed in response to the American H-19 Chickasaw and the deployment of U.S. helicopters during the Korean War. While the Mi-4 strongly resembles the H-19 Chickasaw in general layout, including the innovative engine position in front of the cockpit, it is a larger helicopter, able to lift more weight and built-in larger numbers. The first model entered service in 1953. The helicopter was first displayed to the outside world in 1952 at the Soviet Aviation Day in Tushino Airfield. One Mi-4 was built with a jettisonable rotor. It served as an experimental vehicle for future pilots' means of safety and ejection designs
