Bell 47

This miniature model 47 helicopter from Bell, the first truly successful helicopter in the world, was built in the late 1940s and early 1970s in the amount of 5,000 pieces. Production lines were installed in Italy by Agusta, in the UK by Westland, and Kawasaki in Japan. This helicopter can trace its pedigree from the helicopter model 30 of the 1943 model, which in the amount of ten pieces was ordered for evaluation tests by the US Army.

Following the recommendations of the army for the overall improvement of the helicopter, Bell created Model 47 at the end of 1945, which was the first helicopter certified by the American Civil Aeronautics Authority. Military orders followed in 1947. The U.S. Air Force purchased helicopters under the designation YR-13, and the U.S. Navy – under the designation HTL-1. The US Army also “got into the suit,” having acquired 65 N-13B helicopters the following year. Bell continued to improve its Model 13 as more and more civilian and military orders came in, and in 1953 the company focused its production on the Model I 47G helicopter.

The N-13 military helicopter was widely used to evacuate the wounded in Korea, having accepted this dangerous task from the Grasshopper aircraft of the Second World War. The armed forces of many countries also gained the first experience of the multilateral use of Bell 47 helicopters, and today it remains in operation, albeit in a significantly reduced quantity. Many former Bell 47 military helicopters have fallen into civil registers around the globe, although in recent years a small number of them have again received pseudo-war paint and have joined the collection of the movement of lovers of historic military aircraft.

Bell 47 – a light American helicopter. Designed by Bell’s designer Young Arthur based on the Bell 30. For the first time received a flight certificate in the USA in 1946. It was widely used during the war in Korea (1950-1953) as a connected and search and rescue helicopter.

It was made in various military and civilian modifications (more than 30 options). Depending on the modification and the year of manufacture, it was produced with various types of cockpit and fuselage, equipped with different versions of piston engines (power 200-305 hp).

It was the best helicopter in its class until the late 1960s. It remained in serial production until 1973, in total more than 5600 helicopters were manufactured. It was manufactured by the Italian company Agusta under a license 1954-1976, as well as KawasakiHeavyIndustries (Japan) and WestlandAircraft (Great Britain). The FAA registry (US Aviation Administration) has 1,068 registered Bell47 helicopters.
