Turbofan engine development by Aviadvigatel
Turbofan engine.
PD Engines based on the common core make a family of Russian bypass two-shaft turbojet engines with an efficient noise suppression system intended for short- and medium-haul aircraft and IGTs.
The main specific feature of the PD engine family is the use of a compact common core and a relatively light shroudless fan.
Key technologies: hollow wide-chord titanium blades, blisks and a weld section in the HP compressor rotor, low emission combustor made of intermetallic alloy, single crystal HP turbine blades with an advanced cooling system, ceramic coating on the hot section components, hollow LP turbine blades, nacelle made of composite materials.
