The 1.9 m (75 in) fan has 18 titanium alloy blades, providing an 8.5:1 bypass ratio significantly improved from previous Russian engines, but slightly below the CFM LEAP's 10:1 or the Pratt & Whitney PW1000G's 12:1 for the MC-21 from 2017.

The 3D aerodynamics shaped first high-pressure turbine stage has advanced cooling channels.

Twenty new materials were developed for the powerplant, including monocrystalline alloys for vanes, and high-strength nickel and titanium alloys for shafts and disks.

Developed from the PS-12 (an uprated PS-90A), the 122-153 kN (27,500-34,500 lbf) thrust powerplant is designed by Aviadvigatel and manufactured by the Perm Engine Company.

The two-shaft turbofan has a high-pressure core from the PS-12 with an eight-stage compressor and a two-stage turbine, and four low-pressure stages.

The high-bypass engine does not employ an exhaust mixer, fuel burn should be reduced by 10-15% from the CFM International CFM56 and it could power an upgraded Tupolev Tu-204.
