1. A release mechanism for use in moving in a ram air turbine from a stowed position to a deployed position, the release mechanism comprising:
an extender member operatively connected to the ram air turbine;
a coupler housing extending from a first end to a second end opposite the first end, the coupler housing coupled to the extender member, the coupler housing comprising:
a base arm having an upper surface and a lower surface opposite the upper surface;
a first wall extending away from the upper surface of the base arm, the first wall including a first slot; and
a second wall extending away from the upper surface of the base arm, the second wall including a second slot, wherein the upper surface, the first wall, and the second wall at least partially enclose a cavity therebetween;
a release pivot arm comprising:
a first end;
a second end opposite the first end of the release pivot arm; and
has been amended as—an orifice located proximate the second end of the release pivot arm;
a pivot pin located within the first slot, the second slot, and the orifice, the pivot pin operably connecting the release pivot arm and the coupler housing; and
a solenoid having a solenoid plunger,
wherein, when the solenoid is activated, the solenoid plunger is configured to impact the first end of the release pivot arm, allowing the release pivot arm to move form a first position toward a second position, moving the coupler housing to a position where the extender member moves the ram air turbine to the stowed position; and
wherein, when the solenoid is deactivated, the solenoid plunger is resettled, allowing coupler housing to move to another position wherein the extender member move the ram air turbine to the extended position.
