The Aviadvigatel 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.
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 kgf. Applications are expected in heavy passenger and transport aircraft, such as the Ilyushin Il-96.
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 lbf) 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.
In 2016, Russia started development of a turboshaft variant of the PD-14 to power the Mil Mi-26 heavy lift helicopter.
