Abstract

A dual flow jet engine comprising a core, a surrounding nacelle, delimiting, with the core, a secondary jet, and having a structure and an outer skin fixed to the structure. The nacelle comprises an annular structure through which windows delimited by the annular structure are produced between the secondary jet and the outside. Each window has a regulation system comprising at least one shutter having an outer face, a leading and a trailing edge. Each shutter is mounted articulated at the nacelle structure window at its leading edge and is mobile between a closed position wherein the trailing edge is close to the outer skin and so the shutter closes the window and an open position where the shutter trailing edge moves outwards away from the outer skin to free the window, and for each shutter, a maneuvering system to displace the shutter between the open and closed positions.
