AI Technical Summary
Force conflicts arising from differences in installation tolerances between actuators and sensor accuracy on aircraft control surfaces can cause fatigue damage to the control surface structure. Current technologies require the use of electronic control to calculate and control the differences in actuator output forces in order to alleviate these force conflicts.
Hydraulic devices and unloading valves are introduced into the rudder surface drive system. The actuators and rudder surfaces are connected through hydraulic lines. The hydraulic characteristics are used to achieve real-time passive position compensation, balance the output force, and alleviate force disputes.
It simplifies the zeroing process of the control surface, protects the control surface structure, reduces fatigue damage to the structure caused by control surface force conflicts, and requires no additional software or hardware resources.
