COOLING CIRCUIT FOR A STATOR VANE BRAZE JOINT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240026795 titled 'COOLING CIRCUIT FOR A STATOR VANE BRAZE JOINT
Simplified Explanation
The abstract describes a patent application for a stator vane, which is a component used in gas turbine engines. The stator vane includes a platform with an opening, and an airfoil with a leading edge, trailing edge, suction side wall, and pressure side wall. The airfoil extends between a base and a tip, and either the base or the tip has a protrusion that extends into the opening of the platform. A braze joint is used to fix the platform and the protrusion of the airfoil together, and a cooling circuit is defined in either the protrusion or the platform to cool the braze joint.
- The patent application is for a stator vane used in gas turbine engines.
- The stator vane has a platform with an opening and an airfoil with a leading edge, trailing edge, suction side wall, and pressure side wall.
- The airfoil extends between a base and a tip, and either the base or the tip has a protrusion that fits into the opening of the platform.
- A braze joint is used to fix the platform and the protrusion of the airfoil together.
- A cooling circuit is defined in either the protrusion or the platform to cool the braze joint.

Original Abstract Submitted
a stator vane includes a platform that defines an opening. the stator vane further includes an airfoil that has a leading edge, a trailing edge, a suction side wall, and a pressure side wall. the airfoil extends radially between a base and a tip. at least one of the base or the tip includes a protrusion. the protrusion extends into the opening of the platform such that the platform surrounds the protrusion of the airfoil. the stator vane further includes a braze joint disposed between and fixedly coupling the platform and the protrusion of the airfoil. the stator vane further includes a cooling circuit defined in at least one of the protrusion or the platform to cool the braze joint.
