AI Technical Summary
Current folding wing hinge designs for aircraft fail to effectively isolate flight loads between the fixed and folding wing portions, leading to inefficient load distribution and potential structural stress during folding and unfolding operations.
The proposed folding wing hinge incorporates a hinge pin with a crowned tooth surface and an input fitting spline, coupled with a spline coupling member, allowing for relative movement and forming universal joints to isolate flight loads through a load path that passes through hinge pin bushings, thereby distributing loads efficiently and reducing structural stress.
This design effectively isolates flight loads between the fixed and folding wing portions, enhancing the durability of the hinge pins and reducing the risk of structural damage during folding and unfolding operations, while maintaining the aircraft's aerodynamic efficiency.
