Aviadvigatel PD-14

PD-14
Type Turbofan
National origin Russia
Manufacturer Aviadvigatel
First run November 2010[1]
Major applications Irkut MC-21
Number built 11+
Unit cost less than $5,500,000 USD
Developed from Aviadvigatel PS-90

The PD-14 (earlier PS-14) is a next generation turbofan engine being developed by Aviadvigatel to become one of the alternative power plants for the Irkut MC-21 twin-jet airliner. 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.[2]

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, such as the Ilyushin Il-96.[3][4]

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 MC-21 family, but also for upgraded derivatives of the Tupolev Tu-204, or the UAC/HAL Il-214/IndoRussian MTA multirole aircraft.[5]

In 2016, Russia started development of a variant of the PD-14 to power the Mil Mi-26 heavy lift helicopter.[6]

Design

Russia's answer to the latest turbofan engines for single-aisle aircraft from CFM International and Pratt & Whitney was on public display for the first time at the 2013 MAKS air show. Engine manufacturer Aviadvigatel unveiled the technology demonstrator - bearing serial number 100-01 - of the PD-14, the proposed alternate powerplant for Irkut's in-development MC-21 narrowbody. Although Aviadvigatel has previously displayed scaled mock-ups of the engine, the MAKS show marks the first time the manufacturer has shown off the real example of Russia's latest engine technology.[7]

The engine was displayed with a 1.9m (75 in)-diameter inlet fan composed of 18 blades made from a titanium alloy. The fan diameter provides a bypass ratio of 8.5:1, which is significantly larger compared with previous Russian engines, but still slightly below the 10:1 bypass ratio achieved by the CFM LEAP-1A or the 12:1 ratio of Pratt & Whitney's PW1400G. The latter is the baseline engine selected by Irkut to power the MC-21 at service entry in 2017, but the PD-14 is being pursued as an indigenous option. Aviadvigatel acknowledges the PD-14 would also provide a new core that could be developed into an engine it calls the PD-18R, which would feature a fan-drive gear system similar to the PW1400G. Although the PD-14 display at MAKS revealed that Aviadvigatel has not yet adopted CFM's composite fan blade technology, the Russian manufacturer is catching up in other ways. The first-stage high-pressure turbine of the Russian engine was shown with 3D aerodynamic shaping and advanced interior cooling channels, which are hallmarks of all modern Western engine designs.[7]
