A discrete-vortex method is developed to investigate the wing rock problem associated with highly swept wings. The method uses two logarithmic vortices placed above the wing to represent the vortex flow field and uses boundary conditions based on conical flow, vortex rate of change of momentum, and other considerations to position the vortices and determine their strengths. A relationship based on the time analogy and conical-flow assumptions is used to determine the hysteretic positions of the vortices during roll oscillations. Static and dynamic vortex positions and wing rock amplitudes and frequencies calculated by using the method are generally in good agreement with available experimental data. The results verify that wing rock is caused by hysteretic deflections of the vortices and indicate that the stabilizing moments that limit wing rock amplitudes are the result of the one primary vortex moving outboard of the wing where it has little influence on the wing.Gainer, Thomas G.Langley Research CenterWING ROCK; VORTICES; FLOW DISTRIBUTION; DYNAMIC STABILITY; DELTA WINGS; STABILIZATION; SWEPT WINGS; HYSTERESIS; FLOW VELOCITY; DEFLECTION; CONICAL FLOW; BOUNDARY CONDITIONS; ANALOGIES
