HOUSING STRUCTURE FOR A TURBO ENGINE, TURBO ENGINE AND METHOD FOR COOLING A HOUSING SECTION OF A STRUCTURE OF A TURBO ENGINE

摘要

The invention relates to a housing structure (100) for a turbomachine, a turbomachine and a method for cooling a housing section of a housing structure (100) of a turbomachine, the housing structure (100) comprising an outer housing wall (10) formed by at least one housing part and a inner wall (13), the inner wall (13) being arranged in the radial direction (r) within the housing wall (10) at a distance from the housing wall (10) and being designed to at least partially limit the main flow channel (H), wherein the housing structure (100) comprises a cooling air duct (15) for cooling a housing section (11) to be cooled with an upstream (17) and a downstream end (16), the cooling air duct (15) at least partially between the housing wall (10) and the inner wall (13) and has at least one section (15-1) in which the cooling air duct (15) via de n Cooling air duct inlet (15E), cooling air (K) supplied flows in the direction of the upstream end (17) of the housing section (11) to be cooled, and the cooling air duct inlet (15E) in the region of the downstream end (16) of the housing section (11) to be cooled or is arranged downstream of this.
