Shrouded turbine blade with cooling air outlet port on the blade tip and corresponding manufacturing method

摘要

The present invention relates to a turbine blade (1) for an axial turbo-machine having a blade body (10), extending in a radial direction (11) between a blade root (12) and a blade tip (13), wherein the blade body (10) is provided with at least one inner passage (15) for a cooling medium and at least one outlet port (16) to exhaust the cooling medium from the inner passage (15) to the outer side of the blade tip (13). According to the invention, the outlet port (16) comprises a port axis (17), which is inclined to the radial direction (11).
