CONTROL SYSTEM OF FLYING VEHICLE WITH SECTIONALIZED CONTROL SURFACE Russian patent published in 1995 - IPC

FIELD: manufacture of aircraft. SUBSTANCE: system has control levers 8 and 9 connected with hydraulic drives 3 and 4 of sections 1 and 2 of control surface by means of mechanical linkage 12 with branch 5 and release mechanisms 6 and 11, as well as by means of electric remote channel which consists of two subchannels consisting of force transducers 13 and 14, computers 15 and 16 and servo actuators 17 and 18 with force limiting device 19 and disconnecting device 20. During normal operation of system, servo actuators move sections 1 and 2 through linkage by signals from transducers 13 and 14. In case of failure of one of subchannels, its servo actuator is switched off by respective device 20. In case of seizing of a part of system it is separated from serviceable part by means of mechanisms 6 and 11. In case of derangement of one of servo actuators, its action is overpowered by serviceable servo actuator and by pilot due to operation of device 19. EFFECT: enhanced reliability and improved service characteristics. 1 dwg
