Abstract
Retractable wing-tip mounted vanes are actuated from the normal cockpit controls of an airplane to provide both roll control and direct lift control. When not required, these devices retract into wing fairings. Simple to manufacture and operate, these controls permit reduced manufacturing costs through much simpler wing construction. The vanes consist of suitably constructed plates that slide over one another and which form an end plate to the wing when fully deployed. Asymmetric deployment produces an out-of-balance moment in roll; symmetric deployment induces direct lift by increasing wing lift on both wing panels.
