Stator blade for use in blade adjustment outlet of e.g. turbojet of aircraft, has blade parts arranged against each other to define passages for flow of airflow, and circulation unit for circulating fluid to be cooled by airflow

摘要

The blade (1) has a set of blade parts (3a-3c) arranged against each other to define passages (5a, 5b) for flow of an airflow between the parts. A circulation unit circulates a fluid i.e. oil, to be cooled by the airflow. The parts are superimposed on one another such that gaps between the parts define the passages. The parts are arranged such that the blade comprises an airfoil that is virtually identical to the blade when the blade is observed in a plane orthogonal to a longitudinal direction of the blade. The airfoil comprises a leading edge, a median section and a trailing edge.
