An airfoil of an aircraft is provided with one or more control flaps which are pivotally mounted on the airfoil in an aeromechanically unstable manner. The trailing edges of the control flaps are provided with one or more control tab zones which include trailing portions that deform in response to application of electrical current, heat or pressure thereto. The pitch of the airfoil is constantly controlled by selectively deforming the control tab zones in response to measured signals indicative of variations in fluid pressure acting upon, or motion of th...


A control system for use in controlling the direction of movement of a craft through an oncoming fluid stream, said control system comprising a control member mounted on the craft for rotational movement relative to the oncoming fluid stream about a hinge line which renders the control member substantially mechanically unstable when rotated to any position angularly offset from a reference neutral position relative to the direction of flow of the oncoming fluid stream, said control member having a rounded leading edge facing into the oncoming fluid strea...
