1. A turbine engine extending according to an axis, a circumferential direction around the axis and a radial direction perpendicular to the axis, comprising
a primary flow path for a primary flow, the primary flow path including a compressor, a combustion chamber, and a turbine,
a secondary flow path of a secondary flow, circumferentially surrounding the primary flow path, a fan or a propeller located upstream of the primary flow path and the secondary flow path of the secondary flow,
at least one arm extending radially through the primary flow path, and at least one fluid circulation pipe extending inside the at least one arm, the at least one fluid circulation pipe crossing an entire extent of the at least one arm from a first forward part of an intermediate casing to a radially inner portion of the turbine engine radially inward of the primary flow path,
an upstream portion of the primary flow path being separated from the secondary flow path by the first forward part of the intermediate casing, the intermediate casing located radially between the primary flow path and the secondary flow path, wherein the at least one arm includes an air inlet configured to receive an airflow from the primary flow path so as to cool the fluid circulating in said at least one fluid circulation pipe, the at least one arm including an air outlet located at a radially outer end of the at least one arm and opening into a second middle part of the intermediate casing which is aft of the first forward part of the intermediate casing, the second middle part of the intermediate casing comprising a first duct and a second duct and being located radially between the primary flow path and the secondary flow path, so that the air flow circulates through said air outlet then into the first duct, from the first duct into the second duct and then is discharged into the secondary flow path, the first duct connecting the air outlet of the at least one arm to the second duct, the second duct extends from and fluidly connects the primary flow path to the secondary flow path of the secondary flow.
