Oblique Wing Strut Bracing for Transverse Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oblique wing designs lack strength and stability, performing poorly under transverse bending and not suitable for practical applications due to insufficient structural support.
Innovation Solution
The implementation of a strut or truss-braced configuration for the oblique wing, which includes a mechanical pivot and rotating joints to enhance strength and stability, allowing for variable sweep angles and improved aerodynamic performance across different flight speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an oblique wing design is used to modify wing sweep, then wing sweep can be changed, but the wing lacks strength and stability under transverse bending
Solution Approach 1:
A strut is introduced as an intermediary structural element between the oblique wing and the fuselage. The strut acts as a mediator that transfers and resists transverse bending forces, providing the necessary strength and stability while allowing the wing to maintain its variable sweep capability. The strut connects to the wing root and fuselage through rotating joints, enabling it to function as a structural brace without interfering with the wing's pivoting motion.
2Adaptability or versatility
If a swing wing design is employed to modify wing sweep, then wing sweep can be adjusted, but structural complexity increases
Solution Approach 1:
The wing sweep adjustment mechanism is made dynamic through the use of a pivot joint and actuator system. The oblique wing can rotate about its root to change sweep angles, and the strut incorporates rotating joints that allow it to adapt its orientation relative to the wing and fuselage. This dynamic configuration enables the structure to optimize itself for different flight conditions without requiring multiple separate structural components.
3Strength
If the oblique wing is braced with struts and/or trusses, then strength and stability are improved, but structural weight increases
Solution Approach 1:
The strut is designed with specific geometric parameters optimized for its bracing function. By carefully selecting the strut's length, cross-sectional dimensions, and attachment points, the design achieves maximum structural efficiency. The rotating joints are positioned to optimize force transmission paths, and the strut's orientation relative to the wing and fuselage is adjusted to provide the necessary strength with minimum material usage.
