Abstract
800,882. Automatic steering control systems. SUD-AVIATION, SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Feb. 14, 1956 [Feb. 18, 1955], No. 4624/56. Class 38 (4). [Also in Group XXXIII] An automatic aircraft steering control system is shown in Fig. 9a. A diaphragm 93 is'subjected on one side to total pressure from an aperture 37 on the aircraft, and on the other side to static pressure from an aperture 38. The diaphragm acts on a resistance strain gauge 94. Another diaphragm 96 is subjected, to pressures from apertures 88a and 88b on the lower and upper surfaces of the fuselage, and acts on a strain gauge 97. The strain gauges are each connected in series with a potentiometer 99, and their free ends are connected to an energizing source 98. A signal picked off from potentiometer 99, having components representing functions of airspeed and angle of pitch, is fed to amplifier 100 energizing a torque motor 101 acting on a rod 12 connected to an hydraulic servo 9 controlling a surface 2, and connected through a spring-box 17 to the pilot's control column 15. Strain gauges 103 and 104 are connected to a spring-balanced weight 33 sensitive to acceleration along the z-axis, and a pitchsensitive gyro 43, and the resulting signals are fed to an amplifier 105 energizing a torque motor 106 also acting on rod 12. While the pilot controls the column 15, forces exerted on rod 12 by motors 101, 106 compress the spring box, and are superimposed on the forces exerted by the pilot, and in the steady state, the force on the control column is trimmed out by an adjustable spring 50. When the pilot flies " hands off," the forces exerted by motors 101, 106 keep the aircraft on the course determined by the setting of spring 50. Similar systems are used for the roll and yaw controls, which are each subjected to a force derived from a diaphragm connected to apertures, one on each side of the aircraft, and to a force derived from roll and yaw sensitive gyros respectively.
