Title:
３つのバネを具備するラムエアタービンアクチュエータ
Document Type and Number:
Japanese Patent JP6869164
Kind Code:
B2
Abstract:
A ram air turbine (RAT) actuator can include an actuator housing, an actuator rod configured to move relative to the actuator housing through several positions, and a first biasing member, a second biasing member, and a third biasing member positioned and configured to bias the actuator rod relative to the actuator housing. The first biasing member biases the actuator rod from a first position through a second position, the second biasing member biases the actuator rod from the first position through a third position, and the third biasing member biases the actuator rod from the first position through a fourth position. The three biasing members can be configured to bias a ram air turbine against an uplock hook with sufficient force to eliminate vibrational damage to the uplock hook while in the first position.
