Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft wing designs with adjustable leading edge lifting bodies are prone to safety-critical damage from collisions with foreign objects, leading to unstable flight conditions due to partial or complete detachment of flaps, which compromises the wing's aerodynamic profile and lifting forces.
Innovation Solution
A connecting device is integrated between adjacent leading edge lifting bodies, allowing for controlled relative movement and shock absorption, ensuring the leading edge lifting bodies remain in position even if one positioning device is damaged, thereby distributing external forces and reducing the risk of detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If leading edge lifting bodies are made adjustable to optimize aerodynamic profile for different flight conditions, then aerodynamic performance is improved, but vulnerability to foreign object collision damage increases
Solution Approach 1:
The patent implements a connecting device that acts as a pre-established protective mechanism between adjacent leading edge lifting bodies. This device is designed to absorb and distribute impact forces from foreign object collisions before they can cause catastrophic damage to individual lifting bodies or the wing structure, thereby cushioning the system in advance against harmful effects while preserving aerodynamic functionality.
Solution Approach 2:
The patent divides the leading edge lifting body system into segmented, independently protected units. Each lifting body is connected to adjacent bodies through the connecting device, creating discrete segments that can withstand individual impacts without compromising the entire system. This segmentation allows the aerodynamic system to maintain functionality even when individual segments are damaged.
2Stability of the object's composition
If leading edge lifting bodies are connected rigidly to maintain position, then positioning stability is improved, but risk of catastrophic failure from impact increases
Solution Approach 1:
The connecting device changes the mechanical parameter of connection from rigid to compliant, allowing controlled movement and force distribution. This parameter change enables the system to maintain positioning stability under normal conditions while absorbing impact forces during collision events, preventing catastrophic failure without sacrificing positioning accuracy during operation.
Solution Approach 2:
The connecting device serves as an intermediary element between adjacent leading edge lifting bodies and the main wing structure. It mediates the transmission of forces, allowing controlled relative movement while maintaining overall positional stability. This intermediary function protects the system by distributing impact forces rather than transmitting them directly, reducing catastrophic failure risk while preserving positioning stability.
3Manufacturing precision
If multiple positioning devices are used to secure leading edge lifting bodies, then positioning precision is improved, but vulnerability to partial detachment from impact increases
Solution Approach 1:
The patent merges the positioning functions of multiple leading edge lifting bodies into an integrated system connected by the connecting device. This combining creates a redundant structure where the positioning accuracy and impact resistance of individual bodies are enhanced by their collective connection, allowing the system to maintain positioning precision while distributing impact loads to prevent partial detachment.
