Abstract
A deflector blade suitable for directing jet exhaust of an aircraft rearward or downward has leading and trailing edge portions and an intermediate portion interposed between the edge portions. The three portions and a crank constitute a four-bar linkage connected by four pivots having parallel axes of which a first connects the leading edge portion and intermediate portion, the second connects the crank and the leading edge portion, the third connects the intermediate and trailing edge portions, and the fourth connects the trailing edge portion and the crank. The line connecting the axes of the first and third pivots intersects the connecting line defined by the axes of the second and fourth pivots. When the crank is moved about the axis of the second pivot, the blade is moved between a neutral position for rearward jet exhaust and one of positive angle of deflection in which the jet exhaust is directed downward for providing lift to the aircraft.
