The United Engine Corporation (UEC) has begun supplying serially produced PD-14 engines for the Yakovlev MC-21 program. These engines, designed for the MC-21-310 variant, represent a significant advancement in Russia's aerospace industry.
According to Aeroin, a partner media outlet, Rostec, the state-owned corporation, states that the PD-14 features advanced technologies, including hollow titanium blades and 16 key innovations in materials, coatings, and design.
An initial batch of these engines is being delivered for installation on MC-21 aircraft. The company emphasized that the PD-14 is the first turbofan engine of its kind developed in Russia in the modern era.
A Domestic Alternative to the PW1400G
The PD-14 was conceived as an alternative to the Pratt & Whitney PW1400G, which was originally intended for the MC-21-300 version. However, international sanctions restricted the use of the PW1400G, prompting the need for a domestic solution.
In response, Yakovlev is adapting the MC-21-310 to integrate more Russian-made components, aligning with the country's import substitution policy.
Additionally, the company is working on building a parts inventory to streamline serial production once testing is completed.
Accelerated Development Timeline
Rostec noted that, due to tight schedules, the mass production of aircraft, the development of onboard systems and components, and the test flights of prototypes are all being carried out simultaneously.
