Abstract : The limit-cycle concept is used to sesign a lateraldirectional control system for the B-58. Existing servos and sensors are used, and the mechanical aileron-torudder interconnect is maintained. An analog simulation is used to evaluate the feasibility of the concept as applied to the B-58. The design is evaluated for rolldamper failure, coordination, wing heaviness, and engine failure. The evaluation shows that the concept will usually result in a system with good lateral stability but low Dutch roll damping. The low damping can cause serious pilot coupling. Some possible corrective measures are indicated. (Author)
