SYSTEM FOR DIRECT CONTROL OF AIRCRAFT LIFT FORCE Russian patent published in 1994 - IPC

FIELD: aircraft flight control systems. SUBSTANCE: system is provided with additional angle-of-attack sensor 22, two memory units 23 and 33, two integrators 20 and 28, nine scalers 17, 18, 26, 29, 30, 31, 32, 35 and 36, seven summers 16, 19, 21, 23, 25, 27 and 34 and one preset signal limiter 15 which ensure realization of such laws of control at which rate of deviation of control members is proportional to difference between required and actual accelerations of controllable coordinates. Required accelerations are dictated by requirements for quality of control process and errors of control. Laws of control are realized with no use of servodrives with speed feedback and acceleration sensors. EFFECT: enhanced accuracy of control of preset trajectory due to reduced sensitivity of system to action of external and parametric disturbance. 1 dwg
