CONTROL SYSTEM OF AIRCRAFT CONTROL SURFACES Russian patent published in 2002 - IPC

FIELD: heavier-than-air flying vehicles. SUBSTANCE: control system has control station connected with control surfaces by means of mechanical linkage which includes rigid members and rope section interconnected kinematically; rope section includes cut-out mechanism with bell crank articulated on aircraft skeleton and connected with part of rigid linkage, bearing sector articulated on bell crank axle and spring. Sector and bell crank are interconnected by means of locking mechanism made in form of two levers articulated in sector; each lever is connected with respective length of rope run; these levers are interconnected by means of spring. Levers axles are engageable with stop located between them and mounted on bell crank; they have stepped cut-outs on ends engageable with stop. EFFECT: reduction of space required for installation of control system; avoidance of effect of faulty rope run on control system; enhanced stiffness of control linkage reduced mass of control system. 4 dwg
