Two Soviet aircraft have shared the designation Ilyushin Il-18. The first Il-18 was a propeller-driven airliner of 1946. After a year of test flights, however, the programme was abandoned.

The second Il-18 (NATO reporting name: "Coot") is a large turboprop airliner somewhat resembling the Lockheed L-188 Electra that became one of the best known of Soviet aircraft (over 850 built), and one of the most popular and long lasting, having first flown in 1957. The Il-18 was one of the world's principal airliners for several decades, and was widely exported. Because of the plane's durability, many achieved over 45,000 flight hours.

[edit] Design and development

The Il-18 is a passenger aircraft equipped with four turboprop engines. The aircraft was mass manufactured for 12 years. The popularity of the aircraft was ensured, not just because of its reliability and operational economy, but because of the possibility to increase the number of passenger seats and its flight range for every modification (A, B, V, D and E) as well. The Il-18 was also produced in VIP version («Salon»).

Cubana retrofitted their Il-18s with the Bristol Britannia nosewheel and other parts in the nose gear, to improve the handling on poor runways.^{[citation needed]}

[edit] Operational history

The first Il-18, equipped with NK-4 turboprop engines, flew on 4 July, 1957. On 17 September, 1958 the aircraft first flew with the new AI-20 engines. Vladimir Kokkinaki was the test pilot. Between 1958 and 1960 twenty-five world records were set by this aircraft, among them flight range and altitude records with various payloads. In 1958 the aircraft was awarded the Brussels World Fair Grand Prix. In April 1979 a monument was unveiled at Sheremetyevo airport to commemorate this remarkable aircraft.

Seventeen foreign air carriers acquired 125 Il-18 aircraft, seating 100-120 passengers. Many are still in service in Cuba, Siberia and the Middle East.^{[citation needed]}

[edit] Price

According to Country Studies, Ghana purchased eight Il-18's on credit in 1961, at a price of more than US$1,500,000 each. However, since the operating costs were rather high, four were later returned to the USSR, and others were used by Ghana Airways.
