摘要

The present invention relates to an aircraft engine fan not streamlined (21), this motor (21) comprising a nacelle (22) of general cylindrical shape, in which circulates a primary stream (26), this cradle (22) carrying a fan rotor with blades (33) with variable pitch, which are located radially out of the nacelle (22) to be traversed by a secondary stream (31) flowing longitudinally around the nacelle (22). This rotor comprises a hub (32) carrying the supports of the blade (34) with variable pitch, which each carry a blade (33), each blade (33) comprising a blade extending a foot with which it is removably fixed to a base of the support (34) which the door. Each support base of the blade (34) is situated radially outside of the nacelle (22) to be in the secondary flow path (31), in particular in order to allow the replacement of a blade, without disassembling the remainder of the engine.
