1. A pivot thrust reverser for use in a gas turbine engine assembly, the pivot thrust reverser comprising:

  • a first pivot door forming a first portion of an outer surface of a nacelle when stowed; and

    a second pivot door spaced from the first pivot door forming a second portion of the outer surface of the nacelle when stowed, wherein the pivot doors each form a portion of a surface of a bypass duct when stowed, andwherein in a deployed position the first pivot door and the second pivot door circumferentially surround a portion of an inner surface of a bypass duct such that when the pivot thrust reverser is deployed during engine operation a fan bypass stream is redirected while both a core stream and a nacelle ventilation stream flow in substantially the same manner as when the pivot thrust reverser is stowed.
