ABSTRACT:
The invention is a small flap like device (18) for attachment to the trailing edge (14) of an aircraft wing (10) which improves the coefficient of lift and reduces the coefficient of drag providing an overall increase in fuel economy. The flap (18) is a flat plate-like member having a length (19) of between 0.5% to 1.5% of the chord of the airfoil and at a downward angle (21) to the chord of between 5.degree. and 25.degree..
