The PD-14 engine for the MC-21 aircraft has become one of the most technologically complex projects in the Russian aviation industry in recent decades. During its creation, engineers implemented 16 critically important technologies that were previously unavailable in Russia, ODK stated.
The corporation emphasized that the engine belongs to the fifth generation.
The PD-14 passed tests in volcanic ash conditions and complies with modern ICAO emission standards. Specific fuel consumption is reduced by 10–15% compared to analogues.
The publication "Aviatsiya Rossii" clarified that new hollow wide-chord fan blades, single-crystal turbine blades with 2nd generation thermal barrier coatings, and a low-emission combustion chamber made of intermetallic alloy were developed for the PD-14.
Also, 3D printing of hot section parts, hollow low-pressure turbine blades, and composite sound-absorbing structures were introduced into the power plant.
The day before, "Yakovlev" conducted another flight test of the MC-21 with PD-14: the aircraft took off with only one operating engine. However, the confirmed flight range is not yet impressive — just over 3.8 thousand km.
Aviation expert Roman Gusarov explained to "Pervyy Tekhnicheskiy" that OAK will in any case strive to increase the MC-21's flight range after it enters service.
