Aviadvigatel PD-14

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 MS-21 twin-jet passenger aircraft. The PD-14 was announced in early 2010 with its development cost estimated at RUR 35 billion (US$1.1 billion). The company expects to start certification procedure of PD-14 engine in 2012.^[1]

Information

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 1.97m. The new engine will deliver a 10-11% reduction in fuel burn compared with the CFM International CFM56. Aviadvigatel indicates that the PD-14 will not only be used for the MS-21 family, but also for upgraded derivatives of the Tupolev Tu-204, a modernized and upgraded version of the Ilyushin Il-76 freighter, or the UAC/HAL Il-214/IndoRussian MTA mutirole aircraft.^[2]

Variants

• PD-14 is the initial variant for MS-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 MS-21-200, rated nominally at 122.6 kN (12,500 Kgf; 27,558 lbf) thrust.
• PD-14M is a boosted model of turbofan for MS-21-400, rated nominally at 153 kN (15,600 Kgf; 34,392 lbf) thrust.

Applications

• Irkut MS-21
• UAC/HAL Il-214
