The trend in aircraft systems development to overall electrification includes electrification of flight control actuation system. Generally, there’re two main technologies of «electrical» actuation, which use the power of on-board electrical system to move the aerodynamic surfaces. These technologies are electro-hydrostatic (EHA) and electromechanical (EMA) actuation systems. This paper describes the results of the dynamic testing of electro-backup hydraulic actuator (EBHA), which is one of the possible solutions for actuation systems of the next-generation flying vehicles.
