Stator vane mounting platform

摘要

A stator vane mounting platform is disclosed which provides internal cooling chambers which facilitates the flow of cooling air through the chambers and thus, the cooling of the stator assembly. Baffles define an upstream chamber and a downstream cooling chamber between adjacent stator vanes so as to maximize the airflow and, consequently, the cooling effects of this airflow. The internal cooling chambers are defined by a thick wall and a relatively thin wall, the thin wall being in direct contact with the hot gases passing through the stator assembly. Mounting lugs and flanges are directly attached to the thicker wall so as to mount the stator assembly to the turbine engine structure and to accommodate all of the mechanical stresses encountered during the turbine engine operation.
