A flow measurement apparatus comprising an elongated mounting stem having an inner stem cavity, the mounting stem configured to be mounted in an area of flow to be measured. A probe housing is mounted to an outer surface of the mounting stem and positioned on an upstream side of the mounting stem. The probe housing has a first hole near a center point of the housing and a second, third and fourth hole positioned near the perimeter of the housing. A fifth hole is located on a downstream side of the mounting stem. At least five pressure sensors and a plurality of pressure tapping tubes connecting the holes to the corresponding pressure sensors are included.

A tip structure for a turbine blade comprises a tip surface of an airfoil that extends from a leading edge to a trailing edge and from a pressure side to a suction side of the airfoil. A suction side rail protrudes from the tip surface and comprises: a trailing portion extending flush with the suction side of the airfoil from an origination location at or near the trailing edge to an intermediate location on the suction side; and a leading portion extending from the intermediate location across the tip surface so as to create a suction side shelf region between the leading portion of the suction side rail and the suction side of the airfoil. A pressure side rail protrudes from the tip surface and comprises: a trailing segment extending flush with the pressure side of the airfoil from an origination location at or near the trailing edge to a middle location on the pressure side; and a leading segment extending from the middle location across a camber line on the tip surface so as to create a pressure side shelf region between the leading segment of the pressure side rail and the pressure side of the airfoil.
