Side-opening jet engine nacelle

A nacelle for a jet engine comprising an air intake upstream of the jet engine, a median section surrounding a fan of the jet engine and a downstream section, the nacelle further comprising at least one pair of mobile cowls positioned one on each side of a longitudinal vertical plane of symmetry of the nacelle and articulated substantially parallel to a longitudinal axis of the nacelle about pivot axes so that they can open to give access to the jet engine,

• wherein the mobile cowls are attached to one another by an attachment means that allow the mobile cowls to be articulated to one another about the pivot axes and through which the weight of one cowl acts, when open, on the other cowl that remains closed, there being no fixed structure above the nacelle to directly support the pivot axes about which the mobile cowls are articulated, and
• wherein each mobile cowl comprises means of permanent connection or means for connecting it temporarily, when closed, in terms of rotation to a fixed structure of the nacelle.
