A study was conducted to develop a 4% cambered-airfoil section model with 1% thickness ratio, to measure the surface static pressure distribution of the circular arc airfoil. Surface flow visualization investigations were conducted, using the oil flow technique. Plumbing pipes that deliver surface pressure out of the wind tunnel, were installed inside the airfoil section models for surface pressure measurements. The plumbing pipes were connected by soldering, to form a 4% circular arc airfoil section. The surface of the soldered airfoil was polished, using a 3M Scotch-Brite 7448 Hand Pad. The model was also confirmed to be within 0.1 mm of its optimum shape in terms of dimensional accuracy. Oil flow visualization was performed at Re=62,000, to visualize the flow on the upper surface of the airfoil. The pressure distribution and oil flow visualization results provide information for understanding the structures of attached and separated flowfields.
