  • Aileron for an airplane wing
    Patent number: 4720062
    Abstract: Aileron for an airplane wing controlled by a reversible control system. The aileron comprises a first section extending generally behind the pivot axis of the aileron parallel to the longitudinal axis of the wing and a second section extending in front of the pivot axis of the wing to aerodynamically balance the aileron. The second section is coinciding with the wing tip. To improve the transversal stability of the airplane during drifting flight the second section is directed upwards and outwards with respect to the chord plane of the wing at an angle between 20.degree. and 70.degree. with the chord plane.
