SEALING STRUCTURE FOR A TRANSITION DUCT, INTENDED TO BE INSTALLED BETWEEN THE ROTORS OF HIGH PRESSURE AND LOW PRESSURE TURBINES OF A MULTI-ROTOR ENGINE

摘要

The present invention relates to a seal structure in a transition duct, intended to be placed between the rotor of the high-pressure turbine and the rotor of the low-pressure turbine of a multi-rotor motor. BR/ This structure is characterized in that it comprises a plurality of segments 18 arranged in a ring and forming the inner wall of the transition duct 12, each segment 18 being bolted to one of the bases 20, an anterior cone 34 attached to the anterior portions of the segments 18 and extending inwardly from these portions, a posterior cone 42 attached to the anterior cone 34, at its inner edge, and being connected to the segments 18 near the bases 20, and a sealing member 48, 52, 54 attached to the inner edges of the cones 34, 42.
