Abstract: A coolable airfoil has a passage 94 for discharging particulates entrained in cooling air to provide clean cooling air to the leading edge 60 of the airfoil. A chordwise duct 100 extends past a spanwisely extending supply passage 92 to the inlet of a spanwisely extending rear passage 94 such that momentum effects direct the flow of a portion of cooling air and particulates from the duct, past the entrance of the supply passage 92 and into the rear passage 94. The rear passage 94 has a purge hole 96 through which the particulates may be removed.
