PROBLEM TO BE SOLVED: To improve a system for defrosting a nose cone of an aircraft turbojet. SOLUTION: The turbojet has a bearing which supports, in rotation and in thrust, a low-pressure compressor shaft of axis Z-Z of the engine. The bearing is lubricated with oil by means of two nozzles. A feed tube is fastened to a nose cone of the engine. This tube connects the low-pressure compressor shaft to the engine nose cone. A skin lines the wall of the engine nose cone, leaving a passage for circulation of oil. A plurality of radial oil return tubes is placed between the most eccentric part of the skin relative to the Z-Z axis and the bearing, for returning the oil to the bearing. The return of the oil into the bearing is located at a distance R from the Z-Z axis larger than the radius r of the oil feed tube. COPYRIGHT: (C)2008,JPO&INPIT
