Abstract
A turbine engine assembly includes an airfoil, a first baffle and a second baffle. The first baffle is disposed in a cavity in the airfoil. The first baffle extends spanwise from a first baffle base end to a first baffle tip end disposed at an airfoil tip end. The second baffle is disposed in the cavity longitudinally between and next to the first baffle and an airfoil interior wall. The second baffle extends spanwise from a second baffle base end to a second baffle tip end disposed at the airfoil tip end.
