Low Reynolds Number Experiments on the Wortmann FX61-184 Airfoil

Abstract

The Wortmann FX61-184 airfoil is an 18-percent-thick, single element airfoil designed for low drag and large lift-to-drag ratios. A series of low- speed, two-dimensional wind tunnel experiments was conducted on this airfoil. The airfoil chord was one foot, and chord Reynolds number varied from approximately 0.25 million to 1.0 million at tunnel dynamic pressures of 2.5 to 30 pounds/square foot. Airfoil surface, wake, and tunnel dynamic pressure measurements were taken to determine airfoil performance characteristics. The major experimental parameters varied were Reynolds number and angle of attack. Experimental results are compared with theoretical predictions and previous wind tunnel data at a Reynolds number of 1.0 million.
