The PD-14 was announced in early 2010 with its development cost estimated at RUB 35 billion (US$1.1 billion). The company expects to start the certification procedure for the PD-14 in 2012.〔(In 2011 Aviadvigatel OJSC will develop PD-14 engine demonstrator )〕 The PD-14 turbofan family is planned to be expanded with the geared turbofan PD-18R, with a thrust of 18,000 to 20,000 kg. Applications are expected in heavy passenger and transport aircraft like the Ilyushin Il-96-300/400T.〔(Interfax Russia: Aviation PD-18R jet engine to become most powerful in PD-14 turbofan family ) Allbusiness〕〔(PERM Aircraft Engines: Interview ) PDF, page 11〕 ==Development== The Aviadvigatel company and engine manufacturer Perm Engine Company work on a new engine, without fan and core flows mixing, with a thrust in the 122-153 kN (27,500-34,500 lb) thrust range. Aviadvigatel mentions it would be an upgraded version of the PS-12 engine (an uprated variant of PS-90A engine) that features a classic two-shaft high-bypass architecture. The PD-14 will have a gas-generator design from the PS-12 which includes an eight-stage high-pressure compressor and two-stage high-pressure turbine. Its low-pressure section will have four stages and the fan diameter will be 1.9m. The new engine will deliver a 10-15% reduction in fuel burn compared with the CFM International CFM56. Aviadvigatel indicates that the PD-14 will not only be used for the MS-21 family, but also for upgraded derivatives of the Tupolev Tu-204, or the UAC/HAL Il-214/IndoRussian MTA multirole aircraft.〔(Russian aircraft designers tested yesterday's engine )〕 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「Aviadvigatel PD-14」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
