EXTERNALLY VERIFIABLE THERMAL COMPENSATION OF COWL OPENING ACTUATOR
A cowl door actuator is arranged between a head end and a rod end connected to a cowl door in an aircraft. The cowl door has a closed position and an open position, and the cowl door actuator includes a piston rod that is axially moveable between the head end and the rod end. The piston rod has an extended position in which the piston rod contacts the rod end to move the cowl door to the open position, and a retracted position in which the piston rod is axially spaced from the rod end. When the cowl door is in the closed position, the gap between the piston rod and the rod end enables an axial displacement of the piston rod toward the extended position during thermal expansion of fluid remaining in the actuator, such that the cowl door is maintained in the closed position.
