Abstract
A slot seal closure apparatus for use in an aircraft engine mounting strut comprises at least one door which covers a slot formed in the strut to accommodate fore/aft movement of a portion of the engine cowl. When the engine is in a cruise mode, the movable portion of the cowl is in its forwardmost position disengaged from the slot and the door is in a first position covering the slot so as to prevent airflow through the slot. When the engine is placed in a reverse mode, the movable portion of the cowl moves aft and the door swings to a second position spaced from the slot in reaction to the aft movement of the cowl portion so as to expose the slot thereby enabling the movable portion of the cowl to engage the slot.
