More Information
Summary:A ram air turbine actuator release device to release a ram air turbine actuator includes a lock bolt releasably engaged to the ram air turbine actuator, a toggle comprising a toggle roller to engage the lock bolt, and a toggle pivot to couple the toggle to the ram air turbine actuator, a hydraulic toggle actuator, including a piston defining a first hydraulic chamber and a second hydraulic chamber, a solenoid valve in fluid communication with the first hydraulic chamber, and a plunger coupled to the piston, wherein a pressure differential between the first hydraulic chamber and the second hydraulic chamber displaces the plunger to rotate the toggle to disengage the toggle roller from the lock bolt.
