The Ilyushin Il-114 (Russian Илью́шин Ил-114) is a Russian twin-engine turboprop airliner designed for local routes. In the Antonov An-24 class, it first flew in 1990. Altogether, 20 Il-114s have been built. Production of the Il-114 was terminated in July 2012, with the sixth and last aircraft delivered to Uzbekistan Airlines on 24 May 2013. The decision to end production adheres to the Uzbek government's decision to convert the Tashkent factory to other production lines (namely structural units, household purpose products, spare parts for cars and agricultural equipment), despite Russian interest in keeping the production line and a reportedly high demand prospect for the aircraft. This has translated in an October 2013 announcement by a plant representative, that production is to be resumed after the factory solved financial matters and also due to the interest of a "Russian party".〔(【引用サイトリンク】title=Uzbekistan plans to resume the assembly of Il-114 aircraft - News - Russian Aviation - RUAVIATION.COM )〕 ==Design and development== In June 1986, the Ilyushin OKB began work on a replacement for the Antonov An-24, large numbers of which remained in service with Aeroflot. The Soviet Ministry of the Aviation Industry set down requirement for the An-24 replacement, including the ability to carry 60 passengers over a range of at a speed of , while using much less fuel than its predecessor and retaining the ability to operate out of poorly equipped airfields with unpaved runways.〔Postlethwaite 1990, pp. 100–101.〕〔Duffy 1997, pp. 242–243.〕〔Gordon, Komissarov and Komissarov 2004, p. 352.〕 Development of the new aircraft was expected to be relatively simple, with first flight programmed to take place in 1989 and service entry in 1992.〔 Ilyushin's design, the Il-114, is a low-wing, twin-turboprop monoplane, with an airframe mainly constructed of metal, with composite materials used for non-structural parts. The aircraft is powered by two Klimov TV7-117S turboprop engines driving six-bladed propellers. Undercarriage is a retractable nosewheel undercarrige, while double-slotted trailing edge flaps are fitted to the wings.〔〔Postlethwaite 1989, p. 30.〕 Unlike previous Soviet airliners, which had a large flight crew, the Il-114 is flown by a crew of two, who are provided with electronic flight instruments.〔Postlethwaite 1990, p. 104.〕 Up to 64 passengers are accommodated in the aircraft's cabin, with passenger's baggage carried in compartments at the front and rear of the cabin rather than under the cabin floor.〔〔Postlethwaite 1990, p. 107.〕 The first prototype made its maiden flight from Zhukovsky Airfield on 29 March 1990.〔Jackson 2003, p. 368.〕 Development was slowed by technical problems (including delays with the TV7-117 engines), and by organisational and financial problems associated with the Break-up of the Soviet Union, with the Il-114 to be built at the Tashkent Aviation Production Association in soon to be independent Uzbekistan. The second prototype did not fly until 24 December 1991. This second prototype crashed, killing seven of nine people aboard, on 5 July 1993, causing the Russian government to withdraw funding from the Il-114, although the OKB continued development with its own money.〔Duffy 1997, p. 243.〕〔Gordon, Komissarov and Komissarov 2004, pp. 354–355.〕 The Il-114 finally received airworthiness certification on 26 April 1997.〔Duffy 1997, p. 244.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ilyushin Il-114」の詳細全文を読む スポンサード リンク
