A blade assembly includes a blade and a blade platform secured to the blade. The blade extends radially from the blade platform. The blade platform includes at least one platform airflow passage located therein. A gusset extends from the blade to the blade platform. The gusset includes a gusset airflow passage fluidly connected to the platform airflow passage to convey an airflow to the platform airflow passage. a gas turbine engine includes a combustor and a plurality of gas turbine engine components located in fluid communication with the combustor. The gas turbine engine component includes an airfoil portion and a platform secured to the airfoil portion. The platform includes at least one platform airflow passage positioned therein. A gusset extends from the airfoil portion to the platform. The gusset includes a gusset airflow passage fluidly connected to the platform airflow passage to convey an airflow to the platform airflow passage.

Blade platform gusset with internal cooling

A fixture for disposing laser blocking material on the interior of an airfoil is disclosed. Various construction details are developed which allow for the repetitive disposition of the laser blocking material in one airfoil after another. In one embodiment, the fixture includes a tool member and a nozzle adaptor for providing a sealing surface to a nozzle which extends into the tool member.

Method and fixture for disposing filler material in an article

A method for disposing laser blocking material,on the interior of an airfoil,, such as a rotor blade or stator vane, includes shear thinning the material. Various steps are developed which promote decreases in viscosity of the blocking material. In one detailed embodiment, the material is passed through an injection molding machine,to provide shear thinning.

Method for disposing a laser blocking material on the interior of an airfoil

A tool,for disposing laser blocking material,on the interior of an airfoil,is disclosed. Various construction details are developed which speed the process. In one detailed embodiment, the tool has reciprocatable jaws,which open and close to urge a mask,into engagement with the airfoil.
