A study for the stabilization of lateral motion in heavy passenger transport aircraft is presented. The stabilization can be achieved by the use of a yaw damping device. The natural lateral movements of the aircraft are discussed theoretically. Flight mechanics differential equations were established and linearized. Theoretical determination of the yaw damper was performed. A numerical study of the differential equation system is detailed while the case of jet engine power loss is treated on an analog computer. The yaw damper electronic circuit is presented. Its properties were checked with the help of an analog computer in six cases of typical flight conditions. The problems of matching the damper to the aircraft are discussed in terms of input signal demodulation, input/output impedance matching, and system reliability.
