Abstract
The thrust reverser has an external cowl and a fixed engine core cowl, defining together an annular duct through which high bypass fan air is driven rearwardly. The external cowl has a section adapted to be translated between forward and rearward positions, under control of linear actuators. The translating section includes openings fitted with doors pivotally mounted on the translating section and linked to the engine core cowl so that the translating section translating movement in a rearwardly direction causes the doors to pivot from a stowed position in which they close the openings and a deployed position in which they block the annular duct. The thrust reverser includes only two such doors, the surface area occupied by each door representing more than 30% of the peripheral surface area of the inner wall of a portion of the translating section limited by the vertical planes including the upstream end of the translating section and the pivot axis of the door, respectively.
