The Technodinamika Holding, part of the Rostec State Corporation, is developing an electromechanical thrust reverser actuator system for the PD-14 engine. This is the first system of its kind being created in Russia. The use of electromechanical actuators instead of hydraulic systems will reduce the weight and increase the reliability of the engine.

Elektroprivod,  PJSC (part of Technodinamika) is developing electromechanical thrust reverser actuators for the PD-14 engine designed to power MS-21, Russian short- to medium-range aircraft. Electric actuator prototypes are undergoing research trials as part of the PD-14 engine installed on the IL-76LL flying laboratory.

Hydraulic reverser actuators have been previously developed in Russia. Switch to the electromechanical actuator will reduce weight of the system and improve its performance and maintainability.

“Development of electromechanical reverser actuators for the MS-21 is one more step towards the full-fledged development of the “more electric aircraft” concept,” said Technodinamika CEO Maxim Kuzyuk. “This concept is actively being studied around the world since the abandonment of hydraulic and pneumatic systems significantly reduces weight and improves reliability of aircraft and we have an opportunity to implement this solution in the most advanced Russian engine. This will give us notable competitive advantages in the market as a systems integrator.” He notes that electromechanical reverser actuators have started to be used abroad quite recently and Technodinamika has achieved the level of the world’s companies in this area of competence.
