ABSTRACT:
An auxiliary aerodynamic or hydrodynamic control assembly is provided for a vehicle, such as a guided missile, travelling in a fluid medium, which assembly comprises a number of, say three, control surfaces each carried at the inner end of an arm that is mounted at its outer end on a pivot situated at or near the periphery of a housing of circular cross section, the arm pivots being spaced equidistantly around said periphery. In its neutral or undeflected position each arm extends radially inward from the respective pivot and the control surface it carries, which is generally in the form of a circular arc centered on the pivot, lies retracted wholly within the housing. Angular movement of each arm about its pivot in one direction or the other causes one or the other half of the respective control surface to project from the housing. Different combinations of movement of the several control surfaces give rise to moments in roll, pitch or yaw.
