PD-14

The aviadvigatel PD-14 ( Russian Перспективный Двигатель тягой 14 тонн, , perspective engine with 14 tons of thrust ' or Пермский Двигатель образца 2014 года, , Perm engine model 2014' ) is a turbine jet engine of the Russian manufacturer United Engine Corporation (UEC; Russian Объединенная двигателестроительная корпорация ), an amalgamation of all Russian engine manufacturers. It was developed by Awiadwigatel for the Irkut MS-21 and will also be used in the Sukhoi Superjet .

history

The PD-14 is the first civil aviation jet engine to be completely redeveloped in Russia since the dissolution of the Soviet Union . The first flight took place on November 3, 2015 on a modified Ilyushin Il-76 .

The first flight of the third prototype of the MS-21 with PD-14 was originally planned by the end of 2017, but the engine did not receive certification for Russia until 2018. The manufacturer had undertaken to deliver the first engines to Irkut by the end of 2018. Certification of the MS-21 with the engine around 2021 seemed possible. According to Kommersant, certification by the European EASA was a prerequisite for mass production in summer 2018 .

UEC will produce a total of 16 engines by summer 2019, with three more to follow by the end of the year. At that time, two engines had been delivered to Irkut for testing on the now fourth flying MS-21; the aircraft intended for this was in production in summer 2019.

description

The PD-14 is a twin-shaft turbofan engine with a single-stage low pressure compressor. A gear reduction of the low-pressure compressor wheel was dispensed with in order to be able to keep the diameter small. The low pressure compressor has hollow titanium blades. The complex swirl channels in the combustion chambers are produced using a 3D printing process. The turbine blades are cooled and consist of a single crystal alloy. The engine nacelles consist of 65% composite materials. The PD-14 was developed with the aim of using 10-15% less fuel than the widely used CFM International CFM56 and International Aero Engines V2500 and having 14-17% lower operating costs. According to the manufacturer, the specific fuel consumption of the PD-14 should be comparable to that of the Pratt & Whitney PW1000G and CFM International LEAP , although the low-pressure compressor wheel diameter is smaller (1.90 m, PW1000G: 2.06 m, LEAP: 1.98 m). The finances for the development of the engine came largely from the state budget.

A variant as a compressor for use in the gas industry or as a power plant turbine was up for discussion in 2018 to amortize development costs, but required further development over another 15 years or so.
