The Aviadvigatel PD-14 (previously known as PS-14) is a turbofan being developed by Aviadvigatel to power the Irkut MC-21 twin-jet airliner.

Development

Flight testing on an Il-76

In December 2009, the PD-14 was developed to be 15% more efficient than its PS-90A2 predecessor to be installed on the MS-21 and the Ilyushin Il-276.[4]

The PD-14 was announced in early 2010 with its development cost estimated at RUB 35 billion (US$1.1 billion).[3] In April 2010, Aviadvigatel was expecting to start its certification procedure in 2012.[5] Its core was first tested on 26 November 2010.[6] It was displayed for the first time at the 2013 MAKS air show.[7]

Between December 2016 and May 2017, the PD-14 operational performance and working efficiency at all altitudes and speeds were assessed on an Ilyushin Il-76 testbed at Gromov Flight Research Institute near Moscow.[8]

After two years exploring performance at most altitudes, airspeeds and operating modes, the first and second testing stages confirmed its basic operating parameters. A third phase of flight tests debuted in January 2018 from the Gromov institute at Moscow's Zhukovsky Airfield on an Il-76 testbed, conducted in co-operation with certification specialists to formally confirm the pre-certification efforts findings. Ground tests will continue in parallel and United Engine Corporation claims that the engine matches the foreign competitors performance and surpass them for noise and emissions.[9]Bird strike tests on the fan including high-speed video and vibration measurements were successfully conducted while fan blades strength tests results should reduce the time and cost of the certification.[10]

United Engine will deliver five PD-14s to Irkut by the end of 2018, after Rosaviatsia certification, to start flight tests on the MC-21 in 2019 for type certification of the variant in 2021.[11]EASA certification is expected when it will enter series production.[2]

Design

The 1.9 m (75 in) fan has 18 titanium alloy blades, providing a 8.5:1 bypass ratio significantly improved from previous Russian engines, but slightly below the CFM LEAP's 10:1 or the Pratt & Whitney PW1000G's 12:1 for the MC-21 from 2017. The 3D aerodynamics shaped first high-pressure turbine stage has advanced cooling channels.[7]

Developed from the PS-12 (an uprated PS-90A), the 122-153 kN (27,500-34,500 lbf) thrust powerplant is designed by Aviadvigatel and manufactured by the Perm Engine Company. The two-shaft turbofan has a high-pressure core from the PS-12 with an eight-stage compressor and a two-stage turbine, and four low-pressure stages. The high-bypass engine does not employ an exhaust mixer, fuel burn should be reduced by 10-15% from the CFM International CFM56 and it could power an upgraded Tupolev Tu-204.[]

Proposed derivatives

PD-35

Launched in the summer of 2016 by United Engine Corporation through Aviadvigatel and NPO Saturn, the 35 tf (77,000 lbf) thrust PD-35 will be developed till 2023 for 180 billion rubles ($3 billion) including 60 billion for test benches and laboratory equipment, to power future wide-body aircraft including the Russo-Chinese CRAIC CR929. The 8 m (310 in) long engine will weight 8 t (18,000 lb), its fan will be 3.1 m (120 in) in diameter and its scaled up PD-14 core will have a nine-stage high-pressure compressor and two-stage turbine.[17]

On 19 January 2018, the Russian government awarded UEC-Aviadvigatel a ?64.3 billion ($1.13 billion) contract to develop a PD-35-1 demonstrator by 2023, including wide-chord composite fan blades and fan case, a 23:1 compressor pressure ratio, ceramic matrix composites - silicon carbide-silicon carbide (SiC-SiC) and carbon-silicon carbide (C-SiC) - and advanced cooling for 1,450 °C (2,640 °F) temperatures. It could power the Ilyushin IL-96-400, the Il-476 airlifter, Il-478 tanker and an Antonov An-124 replacement.[18]
