Theoretical And Experimental Studies Of Airfoil Characteristics In Nonuniform Sheared Flow

Work is reported on a continuation of the experimental study of the two-dimensional wing in a three-dimensional sheared flow and also treats the theory of two-dimensional nonuniform sheared flows in an attempt to determine the mechanism responsible for the marked changes in airfoil stall characteristics which were demonstrated experimentally in Reference 3. It was felt desirable to complete the three-dimensional experimental program before resuming experimental work with two-dimensional nonuniform sheared flows. The experimental wing data obtained are presented and compared, where possible, with relevant two-dimensional data and with theory.
