Simulations on flare maneuvers with different pitch angle variations were carried out using the unsteady vortex lattice method (UVLM). The panel method code was satisfactorily validated using wind tunnel test data in free flight. The aircraft aerodynamics and wake development were studied in static and dynamic ground effect. The results show that the lift coefficient of the aircraft increase with a reduction of height in static ground effect, whereas the induced drag coefficient and pitching moment decrease. In dynamic ground effect, the aerodynamic coefficients of the aircraft are history-dependent due to the aerodynamic hysteresis in dynamic ground effect. The aircraft's wake development is influenced by ground effect. It can be concluded that the resultant static stability in ground effect is related to the flight path history of the flight vehicle.
