Nacelle for an aircraft engine with variable section nozzle

A nacelle for an aircraft engine comprising:

• a thrust reverser cowl including a covering upstream section and a nozzle downstream section, the thrust reverser cowl being slidingly mounted along a direction generally parallel to a longitudinal axis of the nacelle, between a direct jet position in which the thrust reverser cowl covers a device for deflecting air flow, and a reverse jet position in which the thrust reverser cowl opens a passage in the nacelle and uncovers the deflecting device;
• at least one actuator for driving displacement of the thrust reverser cowl;
• and
• at least one opening delimited by the nozzle downstream section of the thrust reverser cowl and which is associated to a leakage door, the leakage door being movably mounted on the thrust reverser cowl between a closed position in which the leakage door cooperates with the at least one opening to oppose a flow of the air flow through said at least one opening, and a leakage open position in which the leakage door is retracted to allow for a flow of a portion of the air flow through said at least one opening,
• wherein the leakage door is:
• pivotally mounted between the closed position and the open position about an axis substantially perpendicular to the axis of the nacelle, the pivoting leakage door including:
• an inner skin pivotally mounted on the thrust reverser cowl about a first pivot axis, and
• an outer skin extending opposite the inner skin and pivotally mounted on the thrust reverser cowl about a second pivot axis, wherein the first and second pivot axes are perpendicular to the longitudinal axis of the nacelle and shifted from each other, the first pivot axis being radially closer to the longitudinal axis of the nacelle than the second pivot axis, so that the outer skin has a counter clockwise rotation opening angle from the closed position smaller than that of the inner skin in order to reduce aerodynamic disturbances outside the nacelle when the leakage door occupies the open position.
