Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts with fixed-wing or limited morphing wing structures are unable to adjust to varying navigation or flight environments and complex flow fields, resulting in poor navigation efficiency, stability, and inability to perform high-mobility actions.
Innovation Solution
A wing element structure comprising multiple units connected by airfoil control units and outer edge connecting members, allowing for morphing and variable pitch angle adjustments, which are supported by parallel wing support rods on the aircraft main body, enabling wide-range deformation and adaptation to complex environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-wing structure is adopted, then the structure is simple and stable, but the aircraft cannot adjust to varying navigation or flight environments or complex flow fields, resulting in poor navigation efficiency and stability
Solution Approach 1:
The wing structure is divided into multiple wing element units (leading edge unit, middle unit, trailing edge unit) that can independently morph and adjust. Each unit contains edge members and support rod connecting members that can change configuration, allowing the entire wing to adapt to different flight environments while maintaining manageable complexity through modular design
Solution Approach 2:
The wing structure transitions from a fixed configuration to a dynamic, morphing structure where wing element units can change their shape and configuration in real-time. The support rods and connecting members enable the wing to morph between different states, allowing adaptation to varying navigation environments and complex flow fields while maintaining structural integrity
2Adaptability or versatility
If a limited morphing wing structure is adopted, then some adjustment capability is provided, but the aircraft still cannot achieve high-mobility actions or adapt sufficiently to complex flow fields
Solution Approach 1:
The wing is segmented into multiple independent units with dedicated support rods and connecting members, enabling each segment to morph independently. This segmentation provides wider adjustment range and better adaptability to complex flow fields compared to limited morphing structures, directly improving navigation efficiency and high-mobility actions
Solution Approach 2:
The wing structure enables changes in multiple parameters simultaneously including wing shape, pitch angle, and configuration through the coordinated movement of support rods and connecting members. This multi-parameter adjustment capability allows the wing to optimize performance for different navigation scenarios, significantly improving navigation efficiency and stability
