Aerodynamic Characteristics of Thick Delta Wing
A thick delta wing with a rounded leading egde has been experimentally and numerically studied. To understand the basic flow field of such a wing, experiments have been conducted in the low speed wind tunnel at Nagoya University. Three flow visualizations: oil flow, smoke wire, and tuft methods have been performed, and aerodynamic forces: lift, drag and pitching moment, and pressure distributions have been also obtained. More recently, the total pressure contours are added to these data, so that the location of vortices generated over the upper surface was well identified. The results were compared with those of a thin delta wing as much as possible. Finally, the incompressible Navier-Stokes equations have been solved in order to compare with the experiment.
