Book Description
The aerodynamic effect of shear flow through a series of sensitivity studies of the wind velocity gradients and wing planform geometry parameters is investigated and characterized. The wind shear effect is computed using a modified vortex-lattice computer program and characterized through the formulation of wind shear aerodynamic coefficients. The magnitudes if the aerodynamic effects are demonstrated by computation of the resultant change in the aerodynamics of a conventional wing and horizontal stability configuration on a fixed flight path through a simulated microburst. The results indicate that as much as 20 percent of the control authority of the airplane may be required to counteract the wind-shear-induced forces and moments in the microburst environment.

Book Description
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.
