In December 2009, the PD-14 was developed to be 15% more efficient than its

The PD-14 was announced in early 2010 with its development cost estimated at RUB 35 billion (US$1.1 billion).^[4] 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

Zhukovsky Airfield

, conducted in co-operation with certification specialists to formally confirm the pre-certification efforts findings.

Ground tests will continue in parallel, and

United Engine was to deliver five PD-14s to Irkut by the end of 2018, and after

In October 2018, Rosaviatsia granted certification to the PD-14, and deliveries of the first engines for two MC-21s were expected by the end of 2018. European certificate validation was planned for 2019.[13]

In January 2020, Irkut received the first PD-14 engines to be installed on the MC-21 airliner,^[14] and the first PD-14-powered MC-21-310 made its maiden flight on 15 December 2020 from Irkutsk.^[15]

In October 2021, the engine successfully passed landmark volcanic ash exposure tests. According to Anatoly Serdyukov, the thrust of the PD-14 “practically did not decrease” after the engine was exposed to the presence of the ash for 1 hour.^[16]

Design

The 1.9 m (75 in) fan has 18

's 12:1 for the MC-21 from 2017. The 3D aerodynamics shaped first high-pressure turbine stage has advanced cooling channels.^[7] Twenty new materials were developed for the powerplant, including

Developed from the PS-12 (an uprated

. 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.^{[citation needed]}

. The 8 m (26 ft) long engine will weigh 8 t (18,000 lb), its fan will be 3.1 m (10 ft) in diameter and its scaled up PD-14 core will have a nine-stage high-pressure compressor and two-stage turbine.[29]

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

– 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 A de-rated version would meet the

As of the end of 2022, the PD-35 was postponed until at least 2029.[32]
