A novel means of aircraft yaw and roll control during high-incidence maneuvers
has been developed. We can rapidly control the asymmetry of the vortices
generated over the forebody, and induce desired unsteady yawing and rolling
moments on an aircraft model. We have demonstrated inducement and control
of wing rock using this device, and have developed piecewise-linear transfer
functions relating nosetip motion to wind rolling moment.
