Abstract

An airfoil for a gas turbine engine according to an example of the present disclosure includes, among other things, at least one of an airfoil section and a platform section including a wall. The wall includes a plurality of pedestals having adjacent pedestals extending from an external wall surface to establish a respective cooling passage, and the cooling passage includes an inlet and an outlet. The adjacent pedestals are dimensioned such that the adjacent pedestals taper inwardly from the inlet in a first direction towards the outlet to establish a throat in the respective cooling passage. A method of fabricating a gas turbine engine component is also disclosed.
