First Batch of 'Ready To Fly' Russian Engines Shipped For Installation on MC-21 Airliner
Russian-made PD-14 engines to replace U.S.-sanctioned Pratt & Whitney units on delayed aircraft.
Russia's United Engine Corporation (UEC) has delivered the first batch of PD-14 engines for installation on the MC-21 airliner, which faced delays due to U.S. sanctions blocking access to Pratt & Whitney PW1000G engines.
The PD-14 is the first domestically-produced turbofan engine of this scale in modern Russia. It features 18 titanium alloy fan blades, an 8.5:1 bypass ratio, and advanced cooling channels in the high-pressure turbine. Developed by Aviadvigatel and produced by the Perm Engine Company, the engine delivers 122–153 kN (27,500–34,500 lbf) of thrust.
Rostec stated that airframe reserves and component production are progressing alongside certification tests to expedite the MC-21's entry into serial production. The PD-14-powered MC-21-310 completed its maiden flight in December 2020.
The PD-14 is designed to reduce fuel consumption by 10–15% compared to older Russian engines and could potentially power upgraded aircraft like the Tupolev Tu-204.
