EXHAUST CASING FOR EXHAUST GAS OF GAS TURBINE ENGINE AND GAS TURBINE ENGINE WITH SUCH EXHAUST CASING FOR EXHAUST GAS Russian patent published in 2019 - IPC F01D25/30 F02C7/20 

FIELD: machine building.

SUBSTANCE: exhaust housing for exhaust gas of gas turbine engine comprises annular inner and outer bodies connected by means of a plurality of radial posts to form an annular channel for exhaust gas therebetween. Inner and/or outer housing consists of multiple segments attached to support structure. Segments are attached to the support structure in the areas of fastening distributed over the area of the segments, including the central point of attachment, lateral attachment points and the guide point in the axial direction, which is located on the axial central line of the above segments. Segments are attached at the central attachment point by means of a fastening bolt screwed through the holder on the rear side of the segments into a fastening pin fixed on the support structure. Segments are attached in side attachment points by means of a fastening bolt screwed through the holder on the reverse side of the segments facing the support structure, into the fastening pin fixed on the support structure, as a result of which said holder comprises elongated hole inclined relative to axial and tangential directions. Segments are fixed in guide in axial direction attachment point by means of axial guide pin, which is attached to holder on reverse side of segments and engages in the sliding radial direction the fastening pin fixed on the support structure. Another invention of the group relates to gas turbine engine containing above described exhaust casing.

EFFECT: group of inventions makes it possible to provide compensation of thermal expansion of segments at their resistance to dynamic loads.
