Abstract:

A general low-order surface-singularity panel method is used to predict the aerodynamic characteristics of a problem where a wing-tip vortex from on wing closely interacts with an aft mounted wing in a low Reynolds Number flow i.e., 125,000. Non-linear effects due to wake roll-up and the influence of the two wings on the vortex path are included in the calculation by using a coupled iteractive wake relaxation scheme. The interaction also affects the wing pressures and boundary layer characteristics the effects are also considered using coupled integral boundary layer codes and preliminary calculations using free vortex sheet separation modelling are included. Calculated results are compared with water tunnel experimental data with generally remarkably good agreement. Author
