Turbofan Engine Family for Regional Jet

Advanced turbofan for regional jet is a bypass two-shaft turbojet without fan and core flows mixing and with a thrust reverser and effective acoustic treatment. The aero-engine is designed for a new short- and mid-range regional jet MS‑21.

Advanced turbofan is designed on the basis of a new high-efficient gas generator configured as "8+2" with parameters that are inherent to machines of generation 5+. The gas generator tests and its refinement were started in November 2010.

Engine models

Advanced Turbofan Engine Family for Regional Jet consists of PD-14, PD-14A, PD-14M engine models;

PD-14 is a basic turbofan for MS-21-300 Regional Jet;

PD-14A is a throttled model of turbofan for MS-21-200 Regional Jet;

PD-14M is a boosted model of turbofan for MS-21-400 Regional Jet.

Environmental ratings

  • Emission parameters are at the level of the best world machines of similar design and have good presuppositions for future. Level of NOx emissions is 20...30% lower than that required in ICAO 2008.
  • Noise parameters meet the aircraft noise requirements of ICAO Stage 4 and have 15ĹPNdB margin relative thereto.
