AI Technical Summary

Technical Problem

Traditional turning anti-sway devices are complex in structure, have low integration and poor reliability, and are difficult to meet the space and weight requirements of landing gear for new carriers.

Method used

An EHA (Electronic Harnessing and Anti-Sway) landing gear steering device was designed, which combines steering and anti-sway functions into one. The linear motion of the piston rod is converted into rotational motion, and the EHA power transmission is adopted to eliminate the need for centralized energy and hydraulic lines. The integrated transmission components realize the steering and anti-sway functions.

Benefits of technology

It integrates turning and sway reduction functions, improves the integration and reliability of the device, simplifies the system structure, reduces space occupation and weight, and improves maintainability.
