Introduction

Feb. 29, 2016, ©. Leeham Co: In two articles we have been looking at the new Russian single-aisle aircraft, Irkut MC-21from United Aircraft. Now it’s time to analyze the new Russian engine, PD-14, which is offered as an alternative to the base engine for the aircraft, the Pratt & Whitney PW1400G. 

Summary:

• The PD-14 is a new engine designed by the Aviadvigatel company, a merger of the Soloviev design bureau with the Perm engine company.
• PD-14 is a modern 31klbf design aimed at several Russian aircraft, the first being the MC-21.
• The technology and performance of the PD-14 engine are approaching its Western counterparts, Pratt & Whitney PW1400G and LEAP-1A, but not quite reaching their level. We go through where it differs.
