It is customary to refer to the element between (xj,yj) and ( X J + I , T / J + I ) as the j - t h panel, and to the midpoints of the panels as the control points. Note from Fig. 1 that as one traverses from the z-th boundary point to the (i + 1)th boundary point, the airfoil body is on the right-hand side. , Hi is directed from the body into the fluid and U from the z-th boundary point to the (i + l)-th boundary point with its inclination to the x-axis given by 9{. 5) and v is the disturbance field due to the body which is represented by two elementary flows corresponding to source and vortex flows.

Effect of frequency and mean incidence angle on moment hysteresis loops [28]. 9 Summary 19 CM hysteresis loop of an airfoil which is pitching about zero mean incidence ( % = 0) on the left and about a mean incidence angle ( % = 15) on the right. In both cases, the amplitude of oscillation, a, is 6°. The moment hysteresis loops on the left are similar to those shown in Fig. 14, as one would expect in attached flow. All the loops are for sufficiently high reduced frequency so that they are counterclockwise and hence stabilizing.

It follows from Fig. 2) dy = sin 9 ds We next assume that the airfoil geometry is represented by a finite number (TV) of short straight-line elements called panels, denned by (N -f l)(xj,yj) pairs called boundary points. It is customary to input the (x, y) coordinates starting at the lower surface trailing edge, proceeding clockwise around the airfoil, and ending back at the upper surface trailing edge. 3) then the pairs (xi, y\) and (x^v+i, VN+I) a r e identical and represent the trailing edge.
