| Abstract: | The forces acting on a swept wing in the presence of a vortex induced by a delta wing, as well as the velocity field in the
vicinity of the swept wing, have been measured. By means of the “frozen,” vortex model and a specially-developed numerical
panel method, the forces and moments acting on the wing are calculated from the known velocity field. Comparison of the calculated
and measured force characteristics makes it possible to determine the extent to which the model fits the physical flow pattern.
It is shown that for the intense vortex considered in this study the model gives results which disagree sharply with the experimental
data.
