Cooled turbine vane with improved trailing edge

摘要

The turbine blade (4), mounted on a platform (2) has an aerodynamic section and slots (10) along its trailing edge to extract cooling air circulating in the blade cavity. The outer surface of the blade has a trailing edge extension (12) which projects beyond the slots (10) along the whole edge of the blade from platform to tip. The slots are separated by bridges connecting the inner and outer walls of the blade.
