Aircraft Wing Shift Device for Center of Gravity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft balance and stability are compromised when the center of gravity shifts due to varying payload distributions, leading to inefficiencies and reduced performance, as traditional solutions like ballast decrease payload capacity and performance.
Innovation Solution
An aircraft wing shift device that allows the wing to be dynamically positioned along the fuselage to realign the center of lift with the center of gravity, eliminating the need for ballast by adjusting the wing's position in response to changes in payload and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ballast is added to rebalance the aircraft, then the center of gravity alignment is improved, but the payload capacity decreases
Solution Approach 1:
The wing is made dynamically repositionable along the fuselage using a slide mechanism with apertures, allowing the wing position to be adjusted based on payload distribution. This dynamic adjustment enables the center of lift to be realigned with the center of gravity without adding fixed ballast weight, thus maintaining payload capacity while achieving balance.
Solution Approach 2:
The position parameter of the wing is changed by moving it to different locations along the fuselage (forward or aft positions) corresponding to different payload configurations. This parameter change allows the aircraft to adapt its balance characteristics without modifying its mass distribution through ballast.
2Stability of the object's composition
If ballast is added to rebalance the aircraft, then the center of gravity alignment is improved, but the aircraft performance decreases
Solution Approach 1:
The wing position is made adjustable along the fuselage, enabling real-time or pre-flight adjustment of the center of lift position. This dynamic capability allows the aircraft to maintain optimal performance by aligning centers without the performance penalty of carrying additional ballast weight.
3Device complexity
If the wing position is fixed, then the structural complexity is reduced, but the adaptability to different payload distributions decreases
Solution Approach 1:
The wing mounting structure is segmented into discrete position options along the fuselage, with apertures at specific locations (e.g., forward, center, aft positions). This segmentation provides multiple adaptable positions while keeping each individual mounting point structurally simple, allowing the wing to be repositioned based on payload needs.
4Adaptability or versatility
If the wing is repositioned to accommodate payload changes, then the balance range is extended, but the device complexity increases
Solution Approach 1:
A slide mechanism with multiple apertures is provided, allowing the wing to be dynamically repositioned to at least three different locations along the fuselage. This dynamic system extends the balance range to accommodate various payload distributions while maintaining reasonable structural complexity through a straightforward mechanical design.
