Wing Mount Lateral Connecting Rod for Narrower Aircraft Pylons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft wing mount systems experience high stresses and moments due to third moments (Mx) which necessitate wider pylons, compromising aerodynamic performance.
Innovation Solution
Incorporation of a lateral connecting rod in the wing mount system, offset in both horizontal and vertical transverse directions, to distribute forces and moments, reducing the width of the primary structure while maintaining structural integrity and aerodynamic efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pylon width is increased to manage third moments (Mx) in existing wing mount systems, then structural strength and stress management are improved, but aerodynamic performance deteriorates
Solution Approach 1:
The patent introduces a lateral connecting rod that extends in the horizontal transverse direction (Y-axis), adding a lateral dimension to the force distribution system. This lateral extension allows moments to be managed through side-to-side force distribution rather than increasing the longitudinal width of the primary structure, thus resolving the contradiction between structural strength and aerodynamic performance
Solution Approach 2:
The wing mount system is segmented into multiple independent components: front wing mounts, intermediate wing mount, rear wing mount, and lateral connecting rod. This segmentation allows each component to handle specific force components, with the lateral connecting rod specifically addressing moment management through lateral force distribution, enabling the primary structure to maintain a narrower profile
2Object-generated harmful factors
If the primary structure width is reduced to improve aerodynamic performance, then aerodynamic efficiency is improved, but structural integrity under moment loads deteriorates
Solution Approach 1:
By extending the lateral connecting rod in the horizontal transverse direction, the system manages moment loads through a lateral force path rather than relying on increased longitudinal width. This dimensional shift allows the primary structure to be narrower while maintaining structural integrity through the lateral bracing effect of the connecting rod
Solution Approach 2:
The lateral connecting rod creates an asymmetric force distribution pattern where forces are managed through lateral offsets rather than symmetric widening of the primary structure. This asymmetric arrangement allows the pylon to maintain a streamlined, narrow profile while the lateral connecting rod provides the necessary structural reinforcement against moment loads
