WebNov 27, 2024 · Traditionally, helicopter actuators have mainly been pneumatic actuators [1]. However, in recent years, the focus of the industry has shifted more towards electro-hydraulic and electro-mechanical actuators. In electro-hydraulic actuator (see e.g. [5]), the pressure is directly regulated by an electric motor. An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and … See more The history of the pneumatic actuation system and the hydraulic actuation system dates to around the time of World War II (1938).
