Abstract

In order to represent the free-stream characteristics of a wing with round leading edge shape, a new lifting surface model is proposed. This model is an intermediate model between the nonlinear model and the linear model, and assumes that the free vortices flow along the wing surface until midchord point as the linear model and then leave from the surface at half the angle of attack as the nonlinear model. By making use of this model, the characteristics of the rectangular, delta and swept wings with round leading edge shapes are calculated and compared with experiments. Calculated results almost agree with the experimental ones.
