The specific design features are as follows:

  •  the engine is not equipped with a thrust reverse;
  •  the pylon is in lower position and, therefore, the routing of pipes and wiring as well as interfaces of some systems with an aircraft have been modified;
  •  engine control programs have been updated for higher primary parameters;
  •  corrosion resistance is higher.
