  • Patent number: 4542867
    Abstract: In a hollow airfoil, thin metal baffle sheets are bonded to opposing suction and pressure sides of a longitudinally extending cooling air cavity. The longitudinally extending downstream edges of these opposing baffle sheets are closely spaced apart defining a cooling air outlet slot for the cavity which may, for example, feed cooling air to the trailing edge portion of the airfoil. If the rearward edges of either baffle sheet become unbonded from the inside cavity wall the edge of the baffle sheet might bend inwardly and close the outlet slot. To prevent this possibility a plurality of pedestals extend outwardly from each side of the cavity wall opposite the rearward edge of each baffle sheet and extending substantially to the inwardly facing surface of that baffle sheet trapping it against the wall.
