ABSTRACT:
An aircraft vent door system includes a vent door for a vent on an aircraft door. A cam, having a groove, is disposed on the vent door. The system also includes a movement assembly, which includes a roller disposed within the groove, and a lever coupled to the movement assembly. A portion of the lever extends beyond and proximate to the perimeter of the vent door. A second lever may also be attached to the aircraft door. The first lever pivots in response to the movement of the movement assembly, and urges the second lever to pivot. The second lever, in turn, urges the vent door open, thereby overcoming the sticking effect of, for example, built up ice or other obstructions.
