Starting from 1949, the helicopter passed state tests that did not reveal any complaints about the car, except for the magnitude of the vibration and the level of piloting. During the tests of the rotary-wing machine, the flight speed of 175 km / h and the dynamic ceiling - 5200 meters were reached. The helicopter confidently hung in the air, was distinguished by good stability in flight and excellent maneuverability. Despite a number of plane crashes, the tests could be called successful. Tests of helicopters were organized at the airfield Zakharkovo, near the famous airfield Tushino. " In 1947, it was the Allied OKB-4 of Minaviaprom.ĭue to the lack of own production facilities at OKB-4 at that time, the first three prototypes were built at an aircraft factory in Kiev. A Decemsaw the light of the historic decree “On the creation of a communications helicopter for the USSR Armed Forces”, this was the starting point in the history of the Milvian company, today it is Moscow Mil Helicopter Plant JSC that is part of the Helicopters holding Of Russia. It is on the basis of the NSU that the helicopter was developed, which received the GM-1 index (First Mile Helicopter). This stand was necessary for testing and research of full-sized rotors, as well as refining the design of the main parts of helicopters. Under his direct supervision, a universal test bench of a full-scale helicopter installation (NSU) was created here. In 1946, a helicopter laboratory was formed at TsAGI, headed by Miles. This machine was a three-seater helicopter, built according to the classic single-rotor scheme. In 1945, Mikhail Mil began, on his own initiative, working on an experimental helicopter, which he named EG-1. At the same time, in the war and the first post-war years in the USSR, not a single KB was engaged in single-rotor helicopters. This helicopter scheme still dominates worldwide in the field of helicopter construction. At the same time, the country chose the path of creating helicopters, as they say, of the classical scheme - with one rotor and one tail rotor. The prerequisites for the transition from experimental helicopters to target helicopters, which could be launched into mass production, took shape in the Soviet Union in the middle and second half of the 40s of the last century. The engineer of this squadron was Mikhail Mil, the designer of helicopters glorified in the future. This squadron was used by Soviet troops in the Smolensk defensive battle in the summer of 1941. At the very beginning of World War II in the country, a squadron of military autogyros A-7-3a (the first serial rotary-wing aircraft in the country) of designer Nikolay Kamov was formed. In the USSR, the first autogyros under the designation A-4 designed by Vyacheslav Kuznetsov entered service with the Red Army in the 1934 year. The rotor of such aircraft rotated in flight itself under the action of air flow, it did not have a mechanical drive from the engine. The greatest spread before the Second World War received autogyros. In this case, the prewar years were years of experiments in the field of helicopter. The helicopter turned out to be a much more high-tech machine than many thought, the creation of rotary-wing vehicles was under the force of only truly experienced design teams.

About the excellent flight performance of the rotorcraft "hare" are best said by 27 world records that were set on a helicopter in the period from 1958 to 1968.Īll attempts that were made to create a practical helicopter until the middle of the 1940-s ended in nothing.

The machine is widely used in the air force and civilian aviation Soviet Union. But it all started with the Mi-1 helicopter, which was mass-produced in the USSR, and then in Poland in the passenger, postal, agricultural, sanitary and, of course, military versions. Over its history, Mil Design Bureau has designed 13 main helicopter models and more than 200 of their modifications - from light to super-heavy classes, including the most popular Mi-8 multi-purpose helicopter in world history. We can say that the Mi-1 helicopter began история and the experimental design helicopter bureau bearing the name of the famous aircraft designer Mikhail Mil.
