Actuators : Triumph Controls - UK
Electro-mechanical actuators perform a wide range of movements in various types of applications. Designs are available which provide a rapid and specific travel in trim control in the flying control system of the aircraft. Operation is normally by switch selection and is powered by a DC motor operating trough a gearbox and driving a non-reversible screw to obtain the specified travel. All designs are fully approved and qualification testing is carried out to ensure the units meet the full environmental conditions dictated by the Civil Aviation Authority.
