Release mechanism

A ram air turbine actuation mechanism comprising:

• a spring biased locking piston movable between a first position in which a ram air turbine is held in a retracted position and a second position which releases the ram air turbine;
• and
• a toggle release mechanism comprising:
• a base element;
• a toggle element rotatably mounted at a first end to the base element about a first axis for rotation between a locking position and a release position;
• and
• an actuating rod having a central portion extending through the toggle element and first and second end portions projecting on opposed sides thereof for engagement with actuators arranged on opposed sides of the toggle release mechanism;
• wherein the actuating rod comprises a mounting flange projecting therefrom at a boundary between the central portion and the first end portion, the mounting flange having a first hole therein for receiving a first fastener;
• wherein a surface of the toggle element facing the mounting flange has a bore formed therein for receiving the first fastener;
• and further comprising:
• a mounting element slidably received on the second end portion of the actuating rod, the mounting element having a bore for receiving the second end portion of the actuator rod and a second hole for receiving a second fastener;
• and
• a surface of the toggle element facing the mounting element having a second bore formed therein for receiving the second fastener;
• said locking piston being coupled to a link element of the toggle release mechanism to apply a force thereto in a direction towards said base element of the toggle release mechanism.
