GAS TURBINE ENGINE INTERMEDIATE HOUSING Russian patent published in 2019 - IPC F01D25/16 F02C7/20 

FIELD: engines and pumps.

SUBSTANCE: present invention relates to aircraft and ground-based gas turbine engines (GTE), namely, to GTE power bodies structures, which take up loads, which create both engine (action of weight, thrust force, force from reverse, torque actuation), and obtained during flight of aircraft (from effects of overloads, rolls, pitches and vibrations), which should not cause significant deformations of housing, capable of disrupting engine performance. Disclosed is an intermediate housing, consisting of inner and outer shells, forming flow part of gas turbine engine, connected to each other by power posts, and having front and rear flanges, between rear flange and power posts there are two power brackets. Between the front and rear flanges there are two intersecting cones interconnected, as well as with the front flange and the rear flange, with the formation of triangular circular structures with cutouts, along the edges of which there are reinforcing ribs made diagonally, wherein two power brackets connected to rear flange, two adjacent located power posts, outer shell and one of intersecting cones form closed power pockets.

EFFECT: implementation of the proposed invention with the above distinctive features, together with known features, improves the reliability of the structure due to increasing stiffness of the intermediate housing.
