Abstract

A gas turbine engine article includes an article wall (68) that defines leading and trailing ends and first and second sides that join the leading and trailing ends. The article wall (68) defines a cavity (74). A cooling passage network (76) is embedded in the article wall (68) between inner and outer portions (68a, 68b) of the article wall (68,). The cooling passage network (76) has an inlet orifice (78) through the inner portion (68a) of the article wall (68) to receive cooling air from the cavity (74), a plurality of sub-passages that extend axially from the at least one inlet orifice (78), at least one outlet orifice (85) through the outer portion (68b) of the airfoil wall, and trip strips for mixing cooling air in the cooling passage network (76).
