Engine with chevron pin bank

Abstract:

An apparatus for a turbine engine, such as a gas turbine engine, can include an engine component such as an airfoil. The airfoil includes an outer wall with a pressure side and a suction side confronting a hot gas flow exterior of the airfoil. A cooling circuit can provide a flow of cooling fluid through the interior of the airfoil to cool the airfoil operating within the hot gas flow. The cooling circuit can include a pin bank to induce turbulence on the cooling fluid to improve cooling of the airfoil.
