This miniature helicopter model 47 company "Bell" - the world's first truly successful helicopter - was built at the end of 1940-- early 1970-ies in the number 5000 copies. Production lines have been installed in Italy by "Agusta" in the UK company "Westland" and the company "Kawasaki" in Japan. This helicopter can trace their ancestry from the helicopter model 30 1943, the sample, which is in the amount of ten units ordered for evaluation US Army.

Following the recommendations of the army on overall improvement of the helicopter, Bell created the 1945 model at the end of 47, which was the first helicopter certified by the US Civil Aeronautics Administration. Military orders followed in 1947 year. The US Air Force purchased helicopters under the designation YR-13, and the US Navy - under the designation HTL-1. The US Army also "got into the suit", buying the next year 65 helicopters H-13V. Bell continued to improve its 13 model, as more and more civilian and military orders came in, and in 1953, the company concentrated production on the helicopter model I 47G.

The military helicopter H-13 was widely used to evacuate the wounded in Korea, taking this dangerous task from the airplane "Grsshopper" of the Second World War. The armed forces of many countries also for the first time gained experience in the multilateral use of the Bell helicopter 47, and today it remains in operation, albeit in a significantly reduced amount. Many former military helicopters "Bell" 47 got into civil registers around the globe, although in recent years a small number of them again received a pseudo-military coloring and joined the collection of the movement of fans of historical military aircraft.

Bell 47 is a light American helicopter. Designed by Bell designer Young Arthur on the basis of Bell 30. First received a flight certificate in the USA in 1946. It was widely used during the Korean War (1950-1953) as a liaison and search and rescue helicopter.

Manufactured in various military and civilian versions (more than 30 options). Depending on the version and release, was made with different types of cabin and the fuselage was equipped with different variants of piston engines (power 200-305l.s.).

It was the best helicopter in its class until the end of 1960-x. Remained in serial production to 1973, 5600 cumulatively produced more helicopters. Manufactured by the Italian company Agusta at 1954-1976 license, as well as KawasakiHeavyIndustries (Japan) and WestlandAircraft (UK). In the registry, the FAA (United States Aviation Administration) registered 1068 Bell47 helicopters.
