ISPOLNITELNAYA SYSTEM hydraulic actuated horizontal tail STABILIZER AND METHOD OF TESTING FOR CHECKING THE INTEGRITY OF THE EXECUTIVE

摘要

1. The executive system for a hydraulically actuated stabilizer horizontal tail of the aircraft, having: - two supplied by at least one hydraulic system (A, B) providing a drive (1, 2), each of which is connected to the carrier structural member (M) and arranged to adjust the relative bearing structural part (M) of the stabilizer (H) of the horizontal feathers to bring it into action! - to control the first actuator (1) fluidly connected thereto, the first device (11) a second drive control for the control valve (2) hydraulically connected thereto, the second device (12) of the control valve, which are provided with respectively one hydraulic system (A, B) ,! - operably associated with devices (11, 12) the control valve device (10) monitoring and control which determines the appropriate command signals to the devices (11, 12) control valves, and sends them to perform the appropriate control displacement for driving the actuators (1 2)! - connected to said first actuator (1) a locking device (20) with the locking mechanics for securing the extended position of the stem (7) of the first actuator (1) in its locked state, which is hydraulically by a hydraulic circuit OR is connected to the first hydraulic system (A) and a second a hydraulic system (B) in such a way that in normal operation, at least one of the hydraulic lockup mechanics is in its unlocked state, and when the pressure of both hydraulic systems (a, B) below the minimum unit
