Steady aerodynamic characteristics of a wing flying over a nonplanar ground surface Part II: Channel

Lifting line theory for wing-in-ground effect in proximity to a free surface

“…In addition, a number of numerical and theoretical studies on the WIG have been carried out [12][13][14][15][16][17][18][19][20]. Tan and Plotkin [15] obtained the lift curve slope of a two-dimensional foil in proximity to a rigid ground in the form of series expression using singular perturbation theory.…”

“…And a three-dimensional wing theory for WIG close to a rigid wall was developed based on the Prandtl lifting line theory by Rozhdestvensky [6]. Han et al [16,17] employed the boundary element method to investigate the aerodynamic characteristics for a wing flying over a rail and in channel. The method was shown to be valid by agreement of results with experiment.…”
