Turbine stator vane having a platform with a cooling circuit and corresponding manufacturing method

摘要

A turbine engine component (100) has an airfoil portion (108), which airfoil portion is bounded by a platform (104) at one end. The platform (104) has an as-cast open cavity (102) bordered by at least one as-cast landing (142). A plate (122) is welded to the at least one as-cast landing (142) to cover and close the as-cast open cavity (102).
The invention also extends to a process for forming the turbine engine component (100).
