A PARTIALLY COMPLETED FIXED-GAIN LATERALAUGMENTATION SYSTEM FOR THE B-58 AIRCRAFT.
Abstract
A discussion is given of the design of a fixed-gain lateral augmentation system for the B-58. While the design is only partially completed, there is considerable evidence to indicate that it will be satisfactory over the flight envelope of the B-58 aircraft. The lateral-system general transfer functions were developed for an aileron-rudder interconnect ratio (ARI) equal to minus one, the effect of high-gain in the acceleration loop was qualitatively determined, and the function of the yaw-rate loop was established. A basic concept used in the design of the system was that the problem of pilot coupling during an engine failure will progressively decrease as the damping ratio of the system increases. The prime weakness of the design is the small amount of rudder deflection that the acceleration loop causes, and is due to the design concentrating on damping of the Dutch-Roll frequencies; consequently, during a pulsed aileron input, the system is too slow to reduce lateral accelerations caused by an incorrect ARI ratio which is apparent in four of the six flight conditions tested.
