Abstract
The present disclosure provides for ram air turbine deployment actuator assemblies utilizing an actuator heater. More particularly, the present disclosure provides for ram air turbine deployment actuator assemblies utilizing an integrated electric heater element in the actuator housing. The present disclosure provides that by warming the hydraulic fluid in a ram air turbine deployment actuator assembly via an actuator heating member (e.g., by warming the hydraulic fluid in a hydraulic fluid cavity or chamber that provides an integrated hydraulic snubbing loop), the viscosity of the hydraulic fluid is reduced, thus helping to reduce ram air turbine deployment time via the actuator heating member of the ram air turbine deployment actuator assembly.
