Boost MRA and TRA

Woodward is a leader in the design, development and manufacture of hydraulic boost actuators, in addition to main rotor and tail rotor flight control actuators (MRA/TRA) that control helicopter swash plates. These actuators are typically located in series with the mechanical linkage between the pilot’s cockpit controls and the MRA and TRA, and provide output position proportional to pilot input position but at increased (boosted) force output.
