Abstract
A coolable airfoil having a passage for discharging particulates entrained in cooling air is disclosed. Various construction details are developed to provide clean cooling air to the leading edge of the airfoil. In one embodiment, a chordwise duct extends past a spanwisely extending supply passage to the inlet of a spanwisely extending rear passage 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 and into the rear passage and a larger portion of the flow of cooling air into the supply passage for cooling the leading edge of the airfoil.
