Abstract/Summary The flow around an F/A-18 aircraft at high angle-of-attack is modelled with the aim of predicting the bending moments of the vertical tail resulting from differential buffet pressures on either side of the tail. In order to resolve the unsteady vortex breakdown and its subsequent interaction with the vertical tail, the method of detached-eddy simulation (DES) is used. The results obtained on a fairly coarse mesh show that the main flow dynamics of the vortex breakdown is well captured. A comparison of the fluctuating buffet pressure distribution on both sides of the tail with experimental data shows that reasonable agreement is obtained, although some detail around the leading edge of the tail is missing. However, the prediction of the bending moment is very encouraging considering the relatively coarse mesh used in the computation.
