AI Technical Summary
The existing split-type drag rudder deflection mechanism has a large number of control and transmission parts, poor power transmission effect, resulting in low control synchronization and maneuvering efficiency of the aircraft, as well as increased weight.
A servo motor control system and a matching transmission mechanism are adopted, including a microcontroller, servo motor, crank-slider-eccentric crank mechanism, upper rudder angle and lower rudder angle. The synchronous deflection of the upper and lower split rudders is achieved through the slider-rail assembly, which reduces the number of control components and transmission parts and improves the power transmission effect.
This improved the aircraft's yaw efficiency, reduced wing weight, avoided inconsistent control surface opening and closing angles, and enhanced handling efficiency and control precision.
