Patent ID: 10081440

Abstract:
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 including a toggle roller to engage the lock bolt, and a toggle pivot to couple the toggle to the ram air turbine actuator, a toggle actuator, including an actuation source, and a stroke amplifier, including a piston coupled to the actuation source, a first hydraulic chamber having a first diameter in fluid communication with the piston, a second hydraulic chamber having a second diameter in fluid communication with the first hydraulic chamber, and a plunger in fluid communication with the second chamber, wherein a diameter ratio between the first hydraulic chamber and the second hydraulic chamber amplifies a displacement of the actuation source to displace the plunger to rotate the toggle to disengage the toggle roller from the lock bolt.
