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.

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.

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.

A generator has its length shortened by placing springs in a space in a casing that includes an output shaft, which is driven by an input shaft, and a yoke for separating the two shafts. The generator is assembled by placing a spring in a space in a casing having a first part. The space also has a yoke in it. A rotor bearing is placed in the space adjacent to and impinging upon the spring. A second part of the casing is attached to the first part of the casing so that the spring is pre-loaded therein. The generator also utilizes a guide for holding a spring. The generator also has a thrust plate for applying a force of the springs upon the rotor bearing.

A rectifier assembly includes individual diodes arranged to form a full-wave bridge such that the silicon wafers of the diodes are loaded in compression. As so arranged, the centrifugal forces add to the compression forces on the diodes and on the electrical contacts therewith. The three-phase (AC) input conductors are connected by conductive straps which connect the diodes through to DC (+/&#x2212;) terminal ring outputs. One surface of each of the diodes is in electrical contact with a conductive strap which then connects with the individual (AC) phases of an exciter rotor winding. The opposing surface of the diode contacts the ring diode pad on either the DC (+/&#x2212;) output terminal ring. Two conductive posts, each of which are connected to only one of the DC (+/&#x2212;) output terminal rings permit external connection to a main rotor winding.
