A locking mechanism for a ram air turbine (RAT) includes a base clevis configured to mount to a housing and to have a base link clevis connector portion defining a plurality of base link clevis connector arms and a base link clevis having a base connector portion defining base connector arms that are configure to movably connect to the base link clevis connector arm. The locking mechanism also includes a pin operatively connecting the base connector portion to the base link clevis connector portion in a rotatable relationship and a spring positioned around the pin, wherein a first spring end abuts the base clevis and a second spring end abuts the base link clevis to bias the base link clevis to an unlocked position. A sleeve is positioned between the spring and the pin to maintain a wind diameter of the spring.

Locking mechanisms for ram air turbines

An actuator housing is provided. The actuator housing may comprise a body, and a first side of the body including a first pin interface and a first threaded hole clocked relative to the first pin interface. The first pin interface and the first threaded hole may be configured to interface with a solenoid housing. A second side of the body may be orthogonal to the first side. The second side may include a circular geometry with a cylindrical member disposed central to the circular geometry. A toggle assembly interface may be recessed in the second side and disposed within the cylindrical member.

Actuator housing for ram air turbine deployment actuator

An actuator housing is provided. The actuator housing may comprise a body. A first side of the body may include a first pin interface and a first threaded hole clocked relative to the first pin interface. The first pin interface and the first threaded hole may be configured to interface with a solenoid housing. A second side the body may be disposed adjacent the first side. The second side may include a toggle assembly interface configured to receive a toggle assembly. A third side of the body may be disposed adjacent the first side and the second side. The third side may include an adapter interface configured to receive an adapter for the toggle assembly.
