Abstract : In distinction from the subsonic aircraft in which the system of longitudinal control was quite simple and the favorable conditions of controllability fully assured a rigid kinematic coupling of the control stick with the elevator, the control system on supersonic machines is more complex; it includes hydraulic control boosters, automatic loading units, trimmer effect mechanisms and elements increasing the operational reliability. In modern fighters, an adequate effectiveness of the horizontal tail empennage at supersonic flight modes is achieved only in the presence, in the control system, of a fully rotatable control surface, i.e. of a controlled stabilizer. On the supersonic aircraft having limited maneuverability, longitudinal controllability is porvided by the elevator and by a stabilizer which is adjustable during flight. (Author)
