Aviadvigatel PD-14

Uncommon card · No. 190849

The Aviadvigatel PD-14 (Russian: Авиадвигатель ПД-14) is a wide family of high-bypass turbofan engines that was developed by Aviadvigatel to power the Yakovlev MC-21 twin-jet airliner. Previously known as the PS-12, it is a 14 tf (30,865 lbf) thrust powerplant that allegedly features many new technologies. The goal of the program was to develop a modern fuel efficient power plant capable of competing with modern Western engines. During development, a substantial focus was placed on fuel economy, emissions and international serviceability, areas of traditional weakness for Russian engines such as the Aviadvigatel PS-90. The engine's certification-testing is ongoing in 2026. Current performance and economy claims put the engine on par with the CFM International LEAP and about 5% behind the Pratt & Whitney PW1000G in fuel economy.
