Abstract
An axial flow compressor blade with a cavity formed within the blade tip region and connected by an array of holes onto the pressure side surface of the blade in the tip region so that compressed gas will flow into the cavity, and the cavity is connected by a row of tip slots arranged along the blade tip along the pressure side tip corner to discharge the compressed gas from within the cavity out onto the blade tip toward the oncoming compressed gas flow over the blade tip to reduce or eliminate any boundary layer formation and to reduce blade tip leakage flow.
