AI Technical Summary

Technical Problem

Aircraft wings with movable wing tip devices face challenges in securing the wing tip devices in flight and ground configurations due to limited space for locking systems, especially with increasing wing spans that exceed airport clearance limits.

Method used

A wing hinge assembly with a locking member that moves perpendicular to its axis into a locking channel, allowing for a smaller actuator and reducing the need for complex shaping, and incorporates a guide channel to prevent rotation, distributing load forces effectively.

Benefits of technology

The solution provides secure locking in flight and ground configurations while optimizing space usage and minimizing stress on the locking member, enabling aircraft to comply with airport clearance limits and maintain structural integrity.
