The Aviadvigatel PD-26 is a proposed Russian high-bypass turbofan engine currently under development by Aviadvigatel as part of the PD (Perspektivnyy Dvigatel, “Prospective Engine”) family. It is designed to produce approximately 26,000 kgf (255 kN; 57,000 lbf) of thrust and is intended for use on future wide-body and long-range commercial aircraft.
Design and development
The PD-26 program emerged in the 2020s as a mid-range derivative within Russia’s new-generation engine lineup, positioned between the smaller PD-14 and the larger PD-35. The engine is being developed to support domestically produced wide-body aircraft and reduce reliance on foreign-built powerplants.
The PD-26 is expected to incorporate modern turbofan technologies, including a high bypass ratio, advanced composite fan blades, and improved fuel efficiency compared to earlier Russian engines such as the PS-90. The design is also expected to draw on technologies developed for the PD-14, which serves as the baseline for the PD engine family.
