<p>The structure has a rigid box (10) formed by assembling an upper spar, a lower spar (20), side panels (22) and transverse inner ribs (24), and a rear engine attachment (8) comprising side fittings (26), where each fitting forms a plane attachment interface (36) with a rear attachment body (54). The interface is in the form of straight segment inclined at an angle of 45 degrees from a vertical direction (Z), as seen in section on any transverse plane of the structure, along which distance between the interface and the box increases with increasing distance from upper spar toward the lower spar.</p> |
