    The standard x-y coordinate system for describing the complex curved surfaces of an airfoil has its origin at the leading edge, with the positive x or chordwise dimension extending aft to the trailing edge, and the positive y or thickness dimension extending toward the low-pressure or upper surface of the airfoil.

One of these methods involves the addition of a small aerodynamic element, called a slat, in front of the airfoil.

The slat is mounted ahead of the airfoil in such an attitude as to assist in turning the flow around the leading edge when the airfoil is at a high angle ofFile Size: 2MB.

McAlister. The loading of an airfoil during dynamic stall is examined in terms of the augmented lift and the associated penalties in pitching moment and drag. It is shown that once stall occurs and a leading-edge vortex is shed from the airfoil there is a unique relationship between the augmented lift, the negative pitching moment, and the increase in Size: 2MB.

For the dynamic stall test cases, the airfoil was pitched sinusoidally [ α 15 deg 10 deg sin ω t ]a t f Hz, which corre- sponds to a reduced frequency of k π fc ∕ U ∞ the airfoil in dynamic stall there is an associated increase in both the negative pitching moment and the pressure drag.

For moments less than about —, or drag values greater than aboutthe test data show that either one or two vortices are shed from the vicinity of the airfoilÕs leading edge, and these vortices.
