Claim of US Patent No. 9,139,286

1. An aileron assembly comprising an aileron body, a first spoileron configured to extend from a first surface of the aileron
body, a second spoileron configured to extend from a second surface of the aileron body, and a hinge assembly configured to
move the first and second spoilerons between a retracted position, in which the first and second spoilerons are disposed in
the aileron body, and a deployed position, in which the first and second spoilerons extend from the aileron body, the hinge
assembly comprising a support member on the aileron body, a first hinge member on the first spoileron, a second hinge member
on the second spoileron and an actuating shaft slidably mounted to the support member and configured to slide along a longitudinal
axis of the actuating shaft relative to the support member, wherein the first hinge member is engaged with the actuating shaft
so that the first hinge member is urged to rotate about the actuating shaft in one direction when the actuating shaft is urged
to slide along the longitudinal axis, and the second hinge member is engaged with the actuating shaft so that the second hinge
member is urged to rotate about the actuating shaft in an opposing direction to the first hinge member when the actuating
shaft is urged to slide along the longitudinal axis such that the first and second spoilerons are urged to rotate in opposing
directions about said longitudinal axis.
