Unstructured Navier-Stokes High-Lift Computations on a Trapezoidal Wing

Solutions on a trapezoidal three-element high-lift wing obtained with an unstructured Reynolds averaged Navier-Stokes code are presented. Requirements for grid renemen ts needed to model the pertinent o w physics at various points on the lift curve are identied. Improvements to the lift prediction due to grid renemen t are demonstrated. Lift, drag, pitching moment are shown to be in good agreement with experimental data through C Lmax : The eect of slat and ap brackets are shown, although more grid resolution is needed to correctly capture these eects.
