Abstract
A gurney flap assembly has an actuator and a body. The body has a leading edge and a trailing edge and includes a first panel attaching to the actuator proximate the leading edge, and a second panel attaching to a first hinge at the trailing edge. A second hinge attaches the first and second panel. Linear motion of an actuator output is transposed to the gurney flap, thereby causing the gurney flap to expand and deploy into the airstream on the pressure side of the wing.
