The development of the PD-8V turboshaft engine continues in Samara.
UEC-Kuznetsov is developing the PD-8V helicopter engine for the Mi-26 heavy transport helicopter. On March 23, 2026, at a ceremony awarding the Order of Alexander Nevsky to the company, Kuznetsov CEO Oleg Vydumlev
the project.
The PD-8V will replace the D-136 engines and will be a fully Russian-made powerplant with a digital control system. Development is scheduled for completion in 2031. The PD-8V is expected to be 15% more powerful and offer improved fuel efficiency.
The engine is based on the PD-8 core, whose certification flight tests on the SJ-100 aircraft are nearing completion. Using a previously used hot section reduces the scope of development testing, mitigates technical risks, and simplifies production and service deployment.
The PD-8V turboshaft design features a free turbine to transmit power to the main rotor gearbox and a power takeoff path optimized for helicopter operation modes, including hovering and peak power operation. The engine is equipped with a FADEC digital control system, ensuring stable parameters in all operating modes.
On June 23, 2023, Vadim Badekha, then UEC CEO, announced the start of work on the PD-8V at the opening of the Design Development and Scientific Research Center in Samara. He noted the digital architecture of the control system and the potential for developing a domestic helicopter engine based on the PD-8 gas generator.
