NON-CARBONATED AIRCRAFT AIRCRAFT ENGINE COMPRISING A PLATFORM CARRYING A BLOWER PROPELLER HAVING AUBES WITH FOOTS OUTSIDE THE NACELLE

摘要

The invention relates to a non-ducted fanless aircraft engine (21), said engine (21) comprising a nacelle (22) of generally cylindrical shape, in which a primary stream (26) circulates, said nacelle (22) carrying a fan rotor having vanes (33) of variable pitch which are located radially out of the nacelle (22) to be traversed by a secondary vein (31) flowing longitudinally around the nacelle (22). The rotor comprises a hub (32) carrying variable pitch blade supports (34) each carrying a blade (33), each blade (33) comprising a blade extending a foot by which it is removably attached to a blade (33). base of the support (34) which carries it. Each blade support base (34) is located radially out of the nacelle (22) to be in the secondary vein (31), in particular to allow the replacement of a blade without disassembly of the rest of the engine.
