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.[1]
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.[2][3]
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 MC-21 family, but also for upgraded derivatives of the Tupolev Tu-204, or the UAC/HAL Il-214/IndoRussian MTA multirole aircraft.[4]
In 2016, Russia started development of a variant of the PD-14 to power the Mil Mi-26 heavy lift helicopter.[5]
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.[6]
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.[6]
Variants
- PD-14 is the initial variant for MC-21-300. It is rated nominally at 137.3 kN (14,000 Kgf; 30,865 lbf) thrust.
- PD-14A is a throttled model of turbofan for MC-21-200, rated nominally at 122.6 kN (12,500 Kgf; 27,558 lbf) thrust.
- PD-14M is a boosted model of turbofan for MC-21-400, rated nominally at 153 kN (15,600 Kgf; 34,392 lbf) thrust. The LP turbine is expanded to 5-stages.
Derivative models:
- PD-7 is a derated model, rated nominally at 78 kN (8,000 Kgf; 17,500 lbf) thrust.
- PD-10 is a derated model of turbofan for SSJ-130, rated nominally at 108 kN (11,000 Kgf; 24,300 lbf) thrust.
- PD-18R is a geared turbofan model, rated nominally at 177 kN (18,000 Kgf; 39,800 lbf) thrust.
