Abstract: A system is provided, including an airfoil. The airfoil includes a first suction portion of a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of a suction side as set forth in TABLE I to a maximum of three decimal places, wherein the X and Y values of the suction side are coordinate values that couple together to define suction side sections of the first suction portion of the nominal airfoil profile at each Z coordinate value, the suction side sections of the first suction portion of the nominal airfoil profile are coupled together to define the first suction portion, the airfoil includes an airfoil length along a Z axis, the first suction portion comprises a first portion length along the Z axis, the first portion length is less than or equal to the airfoil length, and the Cartesian coordinate values of X, Y, and Z are non-dimensional values convertible to dimensional distances.

Abstract: A pressure sensor system for a compressor including an inlet bellmouth is disclosed. The system includes a first static pressure sensor positioned within a plane of a plenum that is upstream of the inlet bellmouth; and a second static pressure sensor positioned at an entrance plane of the compressor. A mass flow rate calculator may calculate a mass flow rate based on a pressure differential between the plane of the plenum and the entrance plane of the compressor.
