The Aviadvigatel PD-14 new generation turbofan engine has begun flight testing on board a IL-76 flying test bed aircraft in Russia.

The flight testing of the PD-14 engine which is an engine choice for the new Irkut MC-21 single aisle passenger aircraft, is being carried out by the Gromov Flight Research Institute.

One of the inner port side PS-90A engine of the IL-76 is replaced by the PD-14 for flight testing.

The PD-14 is Russia's answer to the latest western turbofan engine designs like the CFM International LEAP and Pratt & Whitney PW1000 geared turbofan engine family for single aisle aircraft.

PD-14 is the baseline engine for a family of engines with a common core and take off thrust ranging from 8 to 16 tons.


The high bypass two-shaft engine is designed to offer a 10-15 percent lower fuel burn, and features an noise suppression system and a relatively light shroudless fan.

Key technologies include 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.

Uprated models of PD-14 (PD-18R) will be used for re-engining the Tupolev Tu-214, IL-96-300 and IL-96-400Т aircraft.

The MC-21 will be powered by the PD-14 engine in 2017. The Pratt & Whitney PW1400 GTF engine, which is the second engine option, will power its maiden flight scheduled for second half of 2016.
