TURBINE ENGINE BLOWER MODULE, INCLUDING A TURBINE ENGINE INLET CONE DE-ICING SYSTEM, AND DE-ICING METHOD

摘要

The invention relates to an aeronautical turbine engine blower module including a system (10) for de-icing an inlet cone (1) comprising a sheath (30) placed inside an inner space defined upstream by the inlet cone. Said sheath includes a first channel (38) having at least one hot air inlet (42). Said first channel is configured so as to direct hot air from a bearing chamber (22) of the turbine engine to a wall of the inlet cone so as to internally reheat said cone. The sheath also comprises a second channel (40) having at least one outlet located downstream of the inlet of the first channel. Said second channel is configured so as to evacuate the air from the first channel to the downstream end of the turbine engine. The invention also relates to a turbine engine inlet cone de-icing method.
