Apparatus for Deicing a Surface of an Aircraft

摘要

An apparatus for deicing a surface of an aircraft includes a pair of adjacent movable surface elements that lie in a common plane and cover a portion of an aircraft. The pair of surface elements are connected to a reciprocating actuator through a bell crank for reciprocal movement and in opposite directions to one another. The apparatus also includes a tie bar at one end of the surface elements for maintaining the surface elements in a parallel relationship. In a second embodiment of the invention, the apparatus includes a pair of coaxial, coplanar circular disc and a reciprocating actuator for rotating the disc in opposite directions relative to one another.
