Abstract:
1. A propeller assembly including a nacelle housing a turbojet engine, said propeller assembly comprising: an air intake structure capable of directing a flow of air towards a fan of the turbojet engine; and a middle structure including a case surrounding the fan and to which the air intake structure is attached via at least one peripheral inner panel of said air intake structure, wherein the case extends around the fan to essentially vanes thereof, the air intake structure being connected to the case by the peripheral inner panel via at least one structural peripheral flange partially covering the peripheral inner panel and to provide retention of at least one vane in case of loss thereof, the structural peripheral flange being independent of the case and the air intake structure, and the structural peripheral flange being U-shaped and comprising a flat middle portion connecting upstream and downstream ends thereof, wherein the structural peripheral flange extends longitudinally towards the upstream of the air intake structure such that the upstream end of the structural peripheral flange extends over a sector forming an angle of at least 15° defined by the upstream and downstream ends of the structural peripheral flange with a fastening leg of the vanes of the fan, and the upstream end is a free end.
