Abstract
The present invention relates to a low signature jet engine outlet comprising movable border segments forming at least one circular arc and being movable radially for controlling the form and area of the outlet, at least one stationary border element for defining the form and area of the outlet, and movable coupling means for connecting the at least one circular arc to the at least one stationary border element. The coupling means are movable along a connection part of the at least one stationary border element, and the connection part of the at least one stationary border element is substantially flat and extending in a substantially radial direction of the at least one circular arc.
