A system for cooling individual integrated actuator packages (IAPs) positioned throughout the aircraft in a power-by-wire actuation system is disclosed. A low-pressure hydraulic fluid circulates throughout the aircraft to control the temperature of the individual IAPs and to maintain and replenish the hydraulic fluid within the individual IAPs. A thermo-control loop containing low-pressure hydraulic fluid includes a pump, low-pressure hydraulic lines, a heat exchanger, a reservoir and a filter. The entire system provides heat transfer for a high- or low-...
A method of cooling a plurality of actuator assemblies, each of said actuator assemblies being coupled to a control effector, including a flight control surface of an aircraft and each including an actuator having hydraulic fluid therein, a high-pressure pump positioned adjacent said actuator for providing the hydraulic fluid in said actuator under high pressure, and a motor for driving said pump positioned adjacent said pump comprising: pumping hydraulic fluid under high pressure into said actuator from said pump to vary the position of said control eff...
